[0029] The first film 102, the panel substrate 101, and the second film 103 are stacked, It is housed in slot 108-1 and slit 108-2.
[0030] When providing a drive circuit on a panel substrate, even if it is provided as an in-cell type, COG (Chip On It may also be installed using the Glass method or the COF (Chip On Film) method. Figures 1(A) and 1(B) show the socket 109 when installed using the COG method.
[0031] An information processing apparatus according to one aspect of the present invention comprises a foldable panel substrate 101 and a transparent and thickness A first film having a thickness of 50 μm or more and 500 μm or less, preferably 80 μm or more and 150 μm or less. It has 102. By having the first film 102 the surface of the panel substrate 101 To prevent mechanical damage, and the panel substrate 101 is connected to the first housing 104-1 and the second housing 10 This prevents the panel substrate 101 from lifting up from 4-2. The second film 103 is housed between 104-1 and the second housing 104-2. Yes, it is possible. The panel substrate 101 is placed between the first film 102 and the second film 103. It is slidably clamped. This allows the panel substrate 101 to be held between the first housing 104-1 and the second housing It can be supported using the housing 104-2. Also, the pressure associated with operating the touch panel The second film 103 can reduce the amount of deformation of the panel substrate 101. However, Furthermore, in one embodiment of the present invention, the information processing apparatus can perform mechanical surface processing even in a configuration without the second film 103. A configuration that prevents damage can be implemented.
[0032] In one aspect of the present invention, the first film 102 and the second film 103 are each the first It is fixed and supported in the part that contacts the housing 104-1. As shown in Figure 1(A), the first The film 102 is fixed to the first housing 104-1 by the support part 116. The component 103 is fixed to the first housing 104-1 by the support portion 117.
[0033] In one aspect of the present invention, the FPC 107 connects the panel substrate 101 to the circuit board 106. The circuit board 106 is fixed to the first housing 104-1. The folded panel board 101 The frictional force generated between the portion and the first housing 104-1 near the end 111, and the FPC 107 And using the connection with the circuit board 106, the panel board 101 is connected to the first housing 104-1. To gain support.
[0034] In the slit 108-1 of the first housing 104-1, the first film 102 and The flannel substrates 101 may be fixed to each other, and the panel substrate 101 and the second film 10 3 may be fixed to each other. This allows the panel substrate 101 and the first film 10 2. The second film 103 is located within the slit 108-2 of the second housing 104-2. It can slide smoothly. Alternatively, it can slide along the panel substrate in conjunction with the bending operation of the information processing device. The applied stress can be alleviated, or the panel substrate can be prevented from being damaged by stress. can.
[0035] The first film 102 has a region that is not fixed to the panel substrate 101. With the film 102 and the panel substrate 101 fixed together, the information processing device is folded. If this happens, the panel substrate 101 becomes more susceptible to damage due to stress. In one aspect of the present invention, When the information processing device is folded, the first film 102 and the panel substrate 101 The sliding action of these parts reduces damage to the panel substrate 101 due to stress.
[0036] An information processing device according to one aspect of the present invention allows viewing of the display unit through the first film 102. This is possible. In other words, the first film 102 is transparent to light of wavelengths in the visible light region. Figure 2(A) shows the information processing device folded so that the display surface is concave. In this state, the first film 102 has a larger end 110 than the second film 103. It is approaching that. Also, Figure 2(B) shows the information processing device folded so that the displayed surface is convex. It is in a bent state. In this state, the second film 103 is more than the first film 1 It is closer to the end 110 than 02. Thus the first film 102, the second film As 103 and the panel substrate 101 slide against each other, the bending of the panel substrate 101 occurs. This can reduce compressive stress, tensile stress, and other stresses.
[0037] <Explanation of the top view of the panel substrate> In this embodiment, for example, a touch panel 300 can be used as the panel substrate 101. (See Figure 3(A)). Alternatively, the touch panel 400 can be used (Figure 3( See B). Touch panel 300 and touch panel 400 each have a display unit 301. .
[0038] The touch panel 300 or touch panel 400 has a touch sensor, and the touch sensor It includes an area that overlaps with the display unit 301. For example, a sheet-like capacitance that overlaps with the display panel. A type of touch sensor can be used. Alternatively, a so-called in-cell type touch panel can be used. It can be used. In-cell type touch panels have the functionality of touch sensors. For example Alternatively, a capacitive touch sensor may be applied, or an optical touch sensor using a photoelectric conversion element may be used. A touch sensor may be applied. Specifically, a photoelectric conversion element can be used in an optical touch sensor. This is possible (see Figure 3(A) or Figure 3(B)). For example, an optical touch sensor It includes a display unit 301, which comprises multiple pixels 302 and multiple imaging pixels 308. The imaging pixel 308 detects a finger touching the display unit 301 or a finger held over the display unit 301. It is possible to know.
[0039] Pixel 302 comprises multiple sub-pixels (e.g., sub-pixel 302R), and the sub-pixels are light-emitting elements and It is equipped with a pixel circuit.
[0040] The pixel circuit can supply selection signals and image signals. The wiring is electrically connected, and the pixel circuit supplies power to drive the light-emitting elements.
[0041] The touch panel 300 shown in Figure 3(A) includes a scan line drive circuit 303g(1) and an image sensor. It has a signal line drive circuit 303s(1). The scan line drive circuit 303g(1) selects a signal It can be supplied to pixel 302. The image signal line driving circuit 303s(1) drives the image signal. It can be supplied to element 302. Also, the touch panel 400 shown in Figure 3(B) is a scan line drive. It has a motion circuit and an image signal line driving circuit. The scan line driving circuit provides a selection signal to the pixel 302. The image signal line drive circuit can supply the image signal to the pixel 302. In the case where it is provided, the touch panel 400 is located in the area 401 where the socket 109 is positioned. (1) and region 401(2) are provided, and a drive circuit is provided for each using the COG method.
[0042] The imaging pixel 308 comprises a photoelectric conversion element and an imaging pixel circuit, and the imaging pixel circuit comprises a photoelectric conversion element Drive the child.
[0043] The imaging pixel circuit has wiring that can supply control signals and power supply potential. It is electrically connected to the available wiring.
[0044] For example, a signal to select a predetermined imaging pixel circuit and read out the recorded imaging signal, imaging pixel cycle Control signals include signals to initialize the path and signals to determine the time for the imaging pixel circuit to detect light. It can be used as a number.
[0045] The touch panel 300 or touch panel 400 is an image pixel driving circuit 303g(2) and It also includes an imaging signal line drive circuit 303s(2). The imaging pixel drive circuit 303g(2) controls The signal can be supplied to the imaging pixel 308. The imaging signal line drive circuit 303s(2) The imaging signal can be read out.
[0046] Touch panel 300 or touch panel 400 is the area indicated by line segment 406 or line segment 407. It can be folded in a region. For example, a region indicated by line segment 406 is placed near end 111. A region indicated by line segment 407 is placed near hinge 105-1, and the touch panel 300 or The Touch Panel 400 can be folded.
[0047] The touch panel 300 can be folded in the area indicated by line segment 406. For example, scan line The region where the motion circuit 303g(1) and the image signal line drive circuit 303s(1) are located, and the table The touch panel 300 can be folded between the area where the display unit is located. Area 4 Between the area where 01(1) and area 401(2) are located and the area where the display unit is located Then, the touch panel 400 can be folded. This allows the second part 104-1B The area can be reduced. Alternatively, the scan line driving circuit 303 of the touch panel 300 The area of the region where g(1) and the image signal line driving circuit 303s(1) are arranged is the second part It can be made larger than the area of part 104-1B. Or, the area of touch panel 400. The area of the region in which 401(1) and region 401(2) are located is the second part 104-1 It can be made larger than the area of B.
[0048] <Explanation of the top view of the enclosure> First housing 104-1, second housing 104-2, hinge 105-1, slit 108-1 The slit 108-2 and end portion 110 are shown in Figure 4.
[0049] A hinge 105-1 is connected to one side of the second housing 104-2, and the other side of the second housing 104-2 Slits 108-2 are provided on three sides. The end portion 110 is parallel to the axis of rotation of the hinge 105-1. It is provided in the first housing 104-1. A hinge 105-1 is connected to one side of the first housing Slits 108-1 are provided on the other three sides of 104-1. End 111 has a hinge 105- It is positioned parallel to the axis of rotation of 1.
[0050] The panel substrate 101, the first film 102, and the second film 103 are connected to the first housing 1 It is fixed at 04-1. As a result, the information processing device folds at hinge 105-1. Even when bent, the distance between the end 111 and the panel substrate 101, and the distance between the end 111 and the first film The distance between 102 and the distance between end 111 and the second film 103 remain unchanged. On the other hand, The panel substrate 101, the first film 102, and the second film 103 are connected to the second housing 1 It is not fixed to 04-2. As a result, the information processing device folds at hinge 105-1. When bent, the distance between the end 110 and the panel substrate 101, and the distance between the end 110 and the first fill The distance between the 102 segments and the distance between the end 110 and the second film 103 will vary. The distance between the end 110 and the panel substrate 101 is the axis of rotation of the hinge 105-1 and the panel The longer the distance between the substrates 101, the greater the change.
[0051] Furthermore, even if the information processing device is bent at hinge 105-1, the second film 103 If strong bending stress, compressive stress, and tensile stress are not applied, the second film 10 3 may be fixed to the first housing 104-1 and the second housing 104-2.
[0052] Figures 1(A), 1(B), and 4 show a simplified representation of hinge 105-1. Figure 1(B) In the state shown, the axis of rotation of the hinge 105-1 overlaps with the panel substrate 101. As a result of the bending operation of the information processing device, the distance the panel substrate 101 slides, The distance over which film 102 slides and the distance over which film 103 slides are reduced. It is possible.
[0053] The panel substrate 101 separates from the end 110, and the first film 102 separates from the end 110. The second film 103 is separated from the end 110. This allows the information processing device to be folded. As the movement progresses, the panel substrate 101, the first film 102, and the second film 103 slide against each other. However, the panel substrate 101, the first film 102, or the second film 103 are Neither contacts the end portion 110. Also, the end of the first film 102 is always in contact with the second portion 1 This overlaps with 04-2B. As a result, the panel substrate 101, the first film 102, and the second film The end of film 103 falls out of slit 108-2, or the second part 104-2 This prevents collision with the edge of B. Alternatively, the panel substrate 101 and the first film 10 2 or the second film 103 does not come into contact with the end 110. From bending, deterioration, and damage caused by contact, the panel substrate 101, the first film 102, or the second This can prevent the film 103 from being blocked.
[0054] For example, a display unit is provided on the panel substrate 101, and a touch panel is provided on the first film 102. This is possible. The first film 102 and the panel substrate 101 slide against each other, and the sliding action Consequently, the position of the touch panel relative to the display may become misaligned. Also, in the state of misalignment... When location information is entered into a touch panel, unintended information may be entered. For example... Then, a touch panel and a display unit can be provided on the panel substrate 101. This allows, It is preferable that the position of the touch panel relative to the display unit does not shift.
[0055] An information processing apparatus according to one aspect of the present invention consists only of a first film 102 and a panel substrate 101. But that's fine too. At this time, the panel substrate 101 is in slidable contact with the first film 102, and It is supported by the first enclosure 104-1 and the second enclosure 104-2.
[0056] An information processing device according to one aspect of the present invention can also be configured with only three or more films and a panel substrate 101. Good. At this time, the panel substrate 101 has a film that contacts one side and a film that contacts the opposite side. The film is slidably in contact with the first housing 104-1 and the second housing 104-2, and is supported by the first housing 104-1 and the second housing 104-2. It will be done.
[0057] An information processing device according to one aspect of the present invention has a configuration in which multiple hinges are provided and three or more housings are provided That is also good. When one of the connected enclosures that constitute the information processing device is called the first enclosure, Within the slits other than the housing, the first film 102 and the panel substrate 101 are slidable. It's fine to accept it.
[0058] (Embodiment 2) In this embodiment, the information processing device of one aspect of the present invention has a foldable touch panel The configuration of the unit will be explained with reference to Figure 5.
[0059] Figure 5(A) illustrates the structure of a touch panel applicable to an information processing device according to one embodiment of the present invention. This is a top view. In Figure 5(A), each part corresponds to Figure 3(A).
[0060] Figure 5(B) is a cross-sectional view of Figure 5(A) along cutting lines AB and CD.
[0061] Figure 5(C) is a cross-sectional view of Figure 5(A) along the cutting line EF.
[0062] <Explanation of the cross-section> The touch panel 300 has a substrate 310 and a counter substrate 370 facing the substrate 310. (See Figure 5(B)).
[0063] By applying a flexible material to the substrate 310 and the opposing substrate 370, flexibility is achieved. It can be added to the touch panel 300.

[0172] The light-emitting module 580R consists of a first light-emitting element 550R and an optical element (e.g., a first colored layer). It is equipped with 567R.
[0173] The first light-emitting element 550R has a lower electrode, an upper electrode, and a light-emitting element between the lower electrode and the upper electrode. It has a layer containing a compound.
[0174] The light-emitting module 580R has a first colored layer 567R in the direction from which light is extracted. It is sufficient if it transmits light of a specific wavelength, for example, red, green, or blue. A material that selectively transmits the emitted light can be used. A region that allows the light emitted by the optical element to pass through directly may be provided.
[0175] The first colored layer 567R is located in a position that overlaps with the first light-emitting element 550R. Also, see Figure 8(A) The first light-emitting element 550R shown emits light towards the side where the transistor 502t is located. This allows some of the light emitted by the first light-emitting element 550R to reach the first colored layer 567R. The light is transmitted and emitted to the outside of the light-emitting module 580R in the direction of the arrow shown in the figure. One embodiment of the information processing device has a first film 102 in the direction of this arrow.
[0176] <Display Unit Configuration> The display unit 501 has a light-shielding layer 567BM in the direction from which light is emitted. The light-shielding layer 567BM is It is provided so as to surround the colored layer (for example, the first colored layer 567R).
[0177] The display unit 501 includes an insulating film 521. The insulating film 521 covers the transistor 502t. It is used. Furthermore, the insulating film 521 is used as a layer to flatten the irregularities caused by the pixel circuit. This is possible. Furthermore, a laminated film containing a layer that can suppress the diffusion of impurities can be applied to the insulating film 521. This can be achieved, for example, by impurities diffusing from the first colored layer 567R. This can suppress the decrease in reliability of transistors such as the 502t.
[0178] <Touch sensor> The touch sensor 595 is located on the circuit board 510 side of the display unit 501 (see Figure 8(A)). ).
[0179] The resin layer 597 is located between the substrate 510 and the substrate 590, and connects the display unit 501 and the touch sensor 59 Glue together 5.
[0180] <Example of display unit modification 1> Various transistors can be applied to the display unit 501.
[0181] The configuration when a bottom-gate type transistor is applied to the display unit 501 is shown in Figure 8(A) and This is illustrated in Figure 8(B).
[0182] For example, a semiconductor layer containing oxide semiconductors, amorphous silicon, etc., is shown in Figure 8(A). This can be applied to transistors 502t and 503t. Even if the pair of gate electrodes are positioned so as to sandwich the region where the transistor channel is formed from above and below, Good. This helps to suppress variations in transistor characteristics and improve reliability.
[0183] For example, a semiconductor layer containing polycrystalline silicon, etc., is used in the transistor 502 shown in Figure 8(B). It can be applied to transistor t and transistor 503t.
[0184] Figure 8(C) shows the configuration when a top-gate type transistor is applied to the display unit 501. To show.
[0185] For example, a semiconductor layer including polycrystalline silicon or a transferred single-crystal silicon film, etc., is shown in Figure 8. This can be applied to transistors 502t and 503t shown in C). ru.
[0186] This embodiment can be appropriately combined with other embodiments shown herein. .
[0187] (Embodiment 5) In this embodiment, the rotational direction of the housing, as described in other embodiments, will be explained.
[0188] The panel substrate in one aspect of the present invention is preferably a touch panel. The display portion of the touch panel. It is equipped with a touch sensor and the first fill is activated by a thin object such as a pen or pencil, or by a finger. By touching the mu 102, the touch position is detected. That is, the panel substrate 101 is the first It is protected by film 102.
[0189] When the thin tip of the member touches the first film 102, the first film 102 is destroyed. To prevent this, the hardness of the first film 102 is required. The hardness of 02 can be evaluated by a pencil hardness test. The hardness of the first film 102 is To improve this, the first film 102 must have sufficient thickness and sufficient hardness. It is preferable that it be formed from a material.
[0190] The panel substrate 101 may have cracks, wiring, and insulating films due to contact with the tip of a thin component. Multiple weak points 600A exist, such as at the interface. Also, the first film 102 has a thin tip. There are multiple weak points 600B that arise due to contact between components, etc.
[0191] The panel substrate 101 consists of a flexible substrate 601, a flexible substrate 602, and element formation between them. It has a region 603. The element formation region 603 has wiring and inorganic insulating films made of metal layers. These are formed, and their interfaces exist. These interfaces, steps, grain boundaries, etc. are weak areas 600A This is likely to happen. Therefore, vulnerable areas 600A are abundant in the element formation region 603. Element shape When the fragile portion 600A of the formed region 603 breaks, the elements included in the element formation region 603 (for example) However, transistors, capacitive elements, wiring, etc. may be damaged.
[0192] For example, within the range of motion of the enclosure, with the circuit board 602 facing inward, the bending moment 604 is... Bend the substrate 101 so that a curve is formed (see Figure 12(A)).
[0193] When the panel substrate 101 is bent by a bending moment 604, the bending moment 604 In response, tensile stress is generated in the substrate 601 on the convexly bent side of the panel substrate 101. Furthermore, compressive stress is generated in the substrate 602 on the side that is bent into a concave shape. Near the center of 101, there is a surface where neither tensile nor compressive stress occurs; this is called the neutral surface 605. cormorant.
[0194] The magnitude of the stress is 0 at the neutral surface 605 of the panel substrate 101, and the tensile stress is 1 The compressive stress increases linearly toward the surface of substrate 601, and the compressive stress is at the base of panel substrate 101. It increases linearly toward the surface of the board 602. Note that each is on the surface of the panel substrate 101. The stress on the surface of the panel substrate 101 is maximized at the surface of the panel substrate 101. This is called bending stress.
[0195] When tensile stress is applied to the weak point 600A, a crack will start from the weak point 600A, and the weak point 600A becomes the starting point of fracture. On the other hand, when compressive stress is applied to the weak point 6 Because 00A is crushed, it is unlikely to become the starting point for fracture.
[0196] Since the element formation region 603 has thickness, the element formation region 603 is formed only on the neutral plane 605. It is not possible to do so, but if formed near the neutral plane 605, it will occur in the element formation region 603. Bending stress can be reduced. Also, the stress applied to the element formation region 603 is 0 or It is desirable that the direction is compression. That is, the panel substrate has the element formation region 603 in the neutral plane. A configuration with 605 on the inside is preferable. This allows the panel substrate 101 to be bent inward. However, cracks are less likely to occur in the film formed in the element formation region 603.
[0197] The information processing apparatus of the present invention comprises a first film 102 (see Figure 12(B)). The film 102 is not fixed to the panel substrate 101. Also, the first film 10 The panel substrate 101 is bent so that 2 is on the concave side. This causes the front of the touch panel The display can be protected. Alternatively, for example, the panel base from the side of the first film 102. When an external force 606 is applied to the plate 101, the neutral surface 605 on the panel substrate 101 is It moves towards the first film 102, but by reducing the external force 606, the element formation region The tensile stress applied to 603 can be suppressed. Alternatively, in the element formation region 603 This can prevent breakage and cracking.
[0198] Alternatively, the first film 102 is flexible and has a surface other than the surface in contact with the panel substrate 101. It is equipped with a hard coat layer. This allows for the thin tip of a pen or pencil to be removed from the panel base. The board 101 can be protected. Alternatively, the panel base can be made so that the hard coat layer is on the inside. Even when the plate 101 is bent, the stress on the hard coat layer is always zero or in the compressive direction. It is possible.
[0199] The information processing apparatus of the present invention comprises a first housing, a second housing, a panel substrate 101, and a first F The first housing is rotatably connected to the second housing, and the first FI The sheet 102 has a surface that contacts the panel substrate 101, and this surface is bent so that it is convex. In this state, the panel substrate 101 has an element formation region 603 from the neutral plane, and the first film 102 It is provided on the side. In addition, the first film 102 has a hard coat layer on the panel substrate 101 side. ru.
[0200] Furthermore, in one embodiment of the present invention, the information processing apparatus has a first housing that moves within a predetermined range of motion around a rotation axis. It is rotatably connected to the second housing, and a predetermined range of motion is the panel of the first film 102. The rotation is restricted so that the surface on the substrate 101 side becomes flat or convex. When the housing is rotated around the axis of rotation, the element formation region 603 or the hard coat layer This can prevent the generation of tensile stress, or prevent the destruction of the element formation region 603. This can be done. Or, it can prevent the hard court layer from being damaged.
[0201] The first film 102 uses a material that is flexible and transparent to visible light. This is possible. For example, polyethylene terephthalate (PET), polyethylene naphthalate Polyester resins such as PEN, polyacrylonitrile resin, polyimide resin, Methyl methacrylate resin, polycarbonate (PC) resin, polyethersulfone (P ES) resin, polyamide resin, cycloolefin resin, polystyrene resin, polyamide Examples include ion resin, polyvinyl chloride resin, and polytetrafluoroethylene (PTFE) resin. It is preferable to use a material with a low coefficient of thermal expansion, for example, a material with a coefficient of thermal expansion of 3 0 x 10 -6 Polyamide-imide resins, polyimide resins, PET, etc. with a K of / K or less are preferred. It can be used. In addition, a substrate made of glass fiber impregnated with organic resin, or an inorganic filler can be used. It is also possible to use substrates in which the thermal expansion coefficient has been reduced by mixing with a resin. Because the circuit board is lightweight, the display panel using this circuit board can also be made lightweight.
[0202] A thermosetting resin or the like can be used as the material for the hard coat layer of the first film 102. Yes, it is possible. For example, epoxy resin, phenolic resin, unsaturated polyester resin, urea resin Melamine resin, diallyl phthalate resin, silicon resin, vinyl ester resin, polyimi Materials such as polyurethane can be used. These materials are hard and resistant to heat and solvents. It is effective from the viewpoint of surface protection. As the material for the hard coat layer of the first film 102, For example, it is preferable to use urethane acrylate.
[0203] Furthermore, the hard coat layer of the first film 102 may contain silica particles, alumina particles, etc. It is preferable that the first film 102 contains alumina It is preferable that it is coated with a first film 102 made of multiple different materials. A layered structure is also acceptable. For example, a 75 μm thick PE layer on top of a 27 μm thick hard coat layer. A film with a structure in which T films are layered can be used.
[0204] Furthermore, the surface of the first film 102 generates an appropriate amount of frictional force against the finger or other object that comes into contact with it. It is preferable that the first film 102 has been processed to create a certain degree of unevenness. (Textures) may be provided.
[0205] When moving a finger that is in contact with the first film 102, the finger and the first film 102 If the friction is too great, the fingertips can become deformed. This can hinder the delicate movements of the fingertips. Input becomes difficult. Materials that cause excessive friction include those with sufficiently polished surfaces. One example is a flat piece of glass. On the other hand, the friction between the finger and the first film 102 is small. If this happens, the sense of touch on the surface of the fingers is lost.
[0206] As a means of generating appropriate friction on the surface of the first film 102, silica particles and the like are used. The film arranged on the surface can be used as the first film 102. The friction between the finger and the first film 102 can be adjusted to an appropriate level.
[0207] This embodiment can be appropriately combined with other embodiments shown herein. .
[0208] (Embodiment 6) In this embodiment, the present invention can be applied to information processing devices, electronic devices, and the like according to one aspect of the present invention. A method for manufacturing a bendable device will be explained with reference to Figures 9 to 11. Examples of foldable devices include display devices, light-emitting devices, and input devices. Examples of input devices include touch sensors and touch panels. Examples of light-emitting devices. Examples include organic EL panels and lighting devices. Examples include L-panels and liquid crystal displays. Furthermore, touch input is available inside the display and light-emitting devices. In some cases, input devices such as sensors may be included. For example, display devices or light-emitting devices. A touch sensor is located on the opposing substrate (for example, a substrate without a transistor) that the sensor has It may be provided. Or, the element substrate of the display device or light-emitting device (for example, A touch sensor may be provided on the circuit board on which the transistor is located. This involves a counter substrate of the display device or light-emitting device and an element substrate of the display device or light-emitting device. A touch sensor may be provided.
[0209] First, a release layer 703 is formed on the fabricated substrate 701, and a layer to be released 705 is formed on the release layer 703. This is achieved (Figure 9(A)). Furthermore, a release layer 723 is formed on the fabricated substrate 721, and the release layer 723 A peelable layer 725 is formed on top (Figure 9(B)).
[0210] For example, when a tungsten film is used as the release layer, N2O and other substances are added to the tungsten film. Plasma treatment using an oxygen-containing gas, or annealing in an oxygen-containing gas atmosphere. This involves forming a tungsten oxide film in an oxygen-containing gas atmosphere using methods such as sputtering. Using oxidation methods such as the above, a tungsten oxide film is formed between the tungsten film and the layer to be stripped. It is possible.
[0211] At the time of the peeling and transposition process, the tungsten oxide film has a composition of tungsten oxide. It is preferable to include a large amount of compositions in which the ratio of oxygen to tungsten is less than 3. For Sten, when n is a natural number greater than or equal to 1, W n O(3n-1) ,W n O (3n-2) In the case of this homologous series, a crystal optical shear surface exists, and shear occurs when overheated. It becomes cheaper. By performing N2O plasma treatment and forming a tungsten oxide film, The peelable layer can be removed from the substrate by force.
[0212] Alternatively, a tungsten oxide film can be formed directly without forming a tungsten film. For example, a sufficiently thin tungsten film can be subjected to plasma treatment using an oxygen-containing gas. For example, performing annealing in an oxygen-containing gas atmosphere, or in an oxygen-containing gas atmosphere By forming a tungsten oxide film using methods such as sputtering, only the tungsten oxide film can be removed. It may also form as an abscission layer.
[0213] At this time, the interface between the tungsten film and the tungsten oxide film or the interior of the tungsten oxide film By separating them, a tungsten oxide film may remain on the stripped layer side. Then, acid The presence of residual tungsten oxide film can negatively affect the characteristics of the transistor. Therefore, after the separation step of the peeled layer and the layer to be peeled, a step to remove the tungsten oxide film is performed. It is preferable to have it. Note that the above-described method of peeling from the substrate does not necessarily require N2O plasma. Since no processing is required, the step of removing the tungsten oxide film can also be reduced. Therefore, in this case, the device can be manufactured more easily.
[0214] Furthermore, in one aspect of the present invention, tungsten with a thickness of 0.1 nm or more and less than 200 nm is placed on a substrate. A membrane is used.
[0215] The delamination layer contains, in addition to the tungsten film, molybdenum, titanium, vanadium, tantalum, and cinnabar. Films containing ricon, aluminum, or alloys thereof may be used. Furthermore, these films may be used in combination with... A laminated structure with the oxide film may also be used. The release layer is not limited to an inorganic film, but may also be polyimide, etc. Organic films may also be used.
[0216] When using an organic resin for the release layer, if you want to use low-temperature polysilicon as the semiconductor layer... Therefore, the process must be carried out at temperatures below 350°C. Hydrogen baking, hydrogenation for defect termination in silicon, activation of doped regions, etc. This cannot be done sufficiently, and performance is limited. On the other hand, when using an inorganic film, The film temperature is not limited to 350°C, allowing for the development of superior properties.
[0217] When an organic resin is used in the release layer, laser irradiation during crystallization can damage the organic resin and functional elements. Although some images may appear, this problem does not occur when an inorganic film is used as the release layer. This is preferable because it does not occur.
[0218] Furthermore, if an organic resin is used in the release layer, the organic resin will be removed by laser irradiation for resin release. Because it shrinks, it can cause poor contact at the terminals of FPCs, etc. It is difficult to peel and transpose functional elements with a large number of terminals, such as high-resolution displays, with a high yield. There are cases where this is not possible. However, when an inorganic film is used as the release layer, there are no such limitations, and high-definition displays can be produced. Even for functional elements with a large number of terminals, such as sprays, it is possible to peel and transfer them with a high yield. be.
[0219] In one embodiment of the present invention, a method for removing a functional element from a substrate involves applying an insulating layer or a transistor to the fabricated substrate. The layer can be formed at temperatures below 600°C. In this case, high-temperature polysilicon is used for the semiconductor layer. It is possible. In this case, using the conventional high-temperature polysilicon line, the device operation It is possible to mass-produce semiconductor devices that are fast, have high gas barrier properties, and are highly reliable. In this case, an insulating layer and transistor formed by a process at 600°C or below are used. Then, a highly gas-barrier insulating layer is formed above and below the organic EL element under film deposition conditions of 600°C or less. This allows for the placement of impurities such as water into the organic EL element or semiconductor layer. This suppresses the process and, compared to cases where organic resins are used in the release layer, it offers significantly higher reliability. This makes it possible to realize a light-emitting device.
[0220] Alternatively, insulating layers and transistors can be formed on the fabricated substrate at temperatures below 500°C. In this case, low-temperature polysilicon or oxide semiconductors can be used as semiconductor layers, unlike conventional low-temperature polysilicon Mass production is possible using the Risilicon production line. In this case as well, the process is below 500°C. By using an insulating layer and transistor formed with the above and below the organic EL element, temperatures of 500°C or less can be maintained. A highly gas-barrier insulating layer formed under the following film deposition conditions can be placed. This suppresses the incorporation of impurities such as moisture into the organic EL element and semiconductor layer, and the release layer contains organic resin. Compared to methods using other techniques, this method enables the creation of a highly reliable light-emitting device.
[0221] Alternatively, it is possible to form insulating layers or transistors on the fabricated substrate at temperatures below 400°C. In this case, amorphous silicon or oxide grain semiconductors can be used as semiconductor layers, unlike conventional methods. Mass production is possible using the amorphous silicon production line. In this case as well, 400°C By using an insulating layer and transistor formed by the following process, on top of an organic EL element, A highly gas-barrier insulating layer formed under film deposition conditions of 400°C or less can be placed underneath. This suppresses the incorporation of impurities such as moisture into the organic EL element and semiconductor layer, and prevents peeling. Compared to cases where organic resins are used in the abscission layer, a highly reliable light-emitting device can be realized. Cut.
[0222] Next, the fabricated substrate 701 and the fabricated substrate 721 are placed so that the surfaces on which the peel-off layers are formed face each other. To that end, the bonding layers 707 and the frame-shaped bonding layer 711 are used to bond the layers together, and The frame-shaped bonding layer 711 is cured (Figure 9(C)). Here, the frame-shaped bonding layer 711 is formed on the peel-off layer 725. After providing the bonding layer 711 and the bonding layer 707 inside the frame-shaped bonding layer 711, the manufactured substrate 7 Place 01 and the fabricated substrate 721 opposite each other and bond them together.
[0223] Furthermore, it is preferable to perform the bonding of the fabricated substrate 701 and the fabricated substrate 721 under reduced pressure. stomach.
[0224] Note that Figure 9(C) shows the case where the size of the peeling layer 723 is different from that of the peeling layer 703. Alternatively, as shown in Figure 9(D), peel layers of the same size may be used.
[0225] The bonding layer 707 overlaps with the release layer 703, the layer to be released 705, the layer to be released 725, and the release layer 723. Arrange them so that they are in place. The end of the bonding layer 707 is the same as the release layer 703 or the release layer 723. It is preferable that it be located at least one end (the one you want to peel off from the substrate first) inward. This prevents the fabricated substrate 701 and the fabricated substrate 721 from adhering too tightly to each other, and prevents the subsequent This can suppress a decrease in the yield of the peeling process.
[0226] Next, the first peeling point 741 from the substrate is formed by irradiation with laser light (Figure 10( A), (B).
[0227] The fabricated substrate 701 and the fabricated substrate 721 may be peeled off from either side. The size of the peeling layer is different. In this case, the large release layer may be formed on the substrate, or the small release layer may be formed on the substrate. It may be peeled off from the board. Semiconductor elements, light-emitting elements, display elements, etc., are placed on only one of the substrates. When fabricated, the element may be peeled off from the substrate on the side where it was formed, or peeled off from the other substrate. This is also acceptable. Here, we show an example in which the fabricated substrate 701 is peeled off first.
[0228] The laser beam hits the hardened bonding layer 707 or the hardened frame-shaped bonding layer 711 and the peelable layer 7 The region where 05 and the release layer 703 overlap is irradiated. Here, the bonding layer 707 hardens. The following is an example of a state where the frame-shaped bonding layer 711 is not in a hardened state, and the bonded layer 7 in a hardened state. Laser light is shone onto point 07 (see arrow P3 in Figure 10(A)).
[0229] By removing a portion of the peeled layer 705, a first peeling starting point 741 from the substrate can be formed. (See the area enclosed by the dotted line in Figure 10(B)). At this time, not only the peeled layer 705, but also Other layers of the release layer 705, or parts of the release layer 703 and bonding layer 707 may be removed.
[0230] It is preferable to irradiate the substrate with the peeling layer to be peeled off from the substrate side. When irradiating the region where 703 and the peeling layer 723 overlap with laser light, the peeling layer 705 and By introducing cracks only in the peelable layer 705 of the peelable layer 725, a selectively fabricated substrate can be created. 701 and the release layer 703 can be peeled off (see the area enclosed by the dotted line in Figure 10(B)). ).
[0231] When irradiating the region where the peeling layer 703 and the peeling layer 723 overlap with laser light, the peeling layer 703 side A starting point for peeling from the substrate is formed on both the peeled layer 705 and the peeled layer 725 on the peeling layer 723 side. If this happens, it may become difficult to selectively peel off one of the fabricated substrates. Therefore, the laser irradiation conditions are restricted so that cracks can be created only in one of the peeled layers. In some cases, the method for forming the first peeling starting point 741 from the substrate is limited to irradiation with laser light. It may not be formed by cutting, but rather by using a sharp blade such as a cutter.
[0232] Then, from the first peeling starting point 741 from the formed substrate, the peeled layer 705 and the fabricated substrate 7 01 is separated (Figure 10(C), (D)). This allows the peelable layer 705 to be fabricated on the substrate 7 01 can be transferred to the fabricated substrate 721.
[0233] The peelable layer 705 separated from the fabricated substrate 701 in the process shown in Figure 10(D), and the substrate 731 and The materials are bonded together using the bonding layer 733, and the bonding layer 733 is cured (Figure 11(A)).
[0234] Next, a sharp cutting tool such as a cutter is used to form a second peeling point 743 from the substrate. (Figure 11(B), (C)). The method for forming the second peeling starting point 743 from the substrate is a cutter. It is not limited to any sharp blade, and may also be formed by laser light irradiation or other means.
[0235] If the substrate 731 on the side where the release layer 723 is not provided can be cut with a blade or the like, the substrate 731 Incisions may be made in the bonding layer 733 and the peel-off layer 725 (arrow P in Figure 11(B)). (See 5). This removes a portion of the peeled layer 725 and creates a starting point for the second peel from the substrate 7 43 can be formed (see the area enclosed by the dotted line in Figure 11(C)).
[0236] As shown in Figures 11(B) and (C), the fabricated substrate 721 and substrate 731 overlap the release layer 723. If the bonded area is bonded by the bonding layer 733, the fabricated substrate 721 and the substrate The high adhesion of the 731 side reduces the yield in the subsequent peeling process from the substrate. Therefore, a frame-shaped cut is made in the region where the hardened bonding layer 733 and the release layer 723 overlap. It is preferable to make an indentation and form a second peeling starting point 743 from the substrate in the shape of a solid line. This makes it possible to improve the yield in the peeling process from the substrate.
[0237] Then, from the second peeling starting point 743 from the formed substrate, the peeled layer 725 and the fabricated substrate 7 21 is separated (Figure 11(D)). This separates the peelable layer 725 from the fabricated substrate 721. It can be transferred to substrate 731.
[0238] For example, an inorganic film such as a tungsten film that is firmly anchored with N2O plasma, etc. When forming a tungsten oxide film, it is possible to achieve relatively high adhesion during film formation. Subsequently, once a point of delamination is formed, cleavage occurs from that point, easily separating the layer to be delaminated. It becomes possible to transfer the substrate from the fabricated substrate to the new substrate.
[0239] Furthermore, a liquid such as water is permeated into the interface between the release layer 723 and the layer to be released 725 to produce the substrate 72 1 and the peeled layer 725 may be separated. Due to capillary action, the liquid separates from the peeled layer 723. By seeping between layers 725, the static electricity generated during delamination from the substrate is absorbed into the delamination layer 725. It can adversely affect functional elements such as FETs (semiconductor elements can be destroyed by static electricity). It can suppress (such as).
[0240] Furthermore, when applying a physical force to a MOW bond (where M is any element) to break the bond... As the liquid seeps into the gap, the M-OH and HO-W bonds are formed. Because the distance between them increases, separation can be promoted.
[0241] The liquid may also be sprayed in the form of a mist or vapor. Examples of liquids include pure water and organic solvents. It can be used in neutral, alkaline, or acidic aqueous solutions, or in aqueous solutions containing dissolved salts. Liquids or other substances may also be used.
[0242] Furthermore, the temperature of the liquid and substrate during mechanical delamination is preferably between room temperature and 120°C. It is best to keep the temperature between 60°C and 90°C.
[0243] In the method for peeling from a substrate according to one aspect of the present invention described above, a sharp blade or the like is used to peel from the substrate. A second delamination starting point 743 is formed, and the delamination layer and the layer to be delaminated are made easier to separate. The fabricated substrate is peeled off. This improves the yield of the peeling process from the substrate. can.
[0244] Furthermore, after bonding together a pair of fabricated substrates, each having a peelable layer formed on it, Each fabricated substrate can be peeled off, and the substrates that make up the device to be fabricated can be bonded together. Therefore, when bonding the peel-off layers, bond together fabricated substrates with low flexibility. This allows for a higher alignment accuracy of the bonded substrates compared to when flexible substrates are bonded together. It can be improved.
