[0055] The following provides a detailed description of a component substrate, an electronic modulation device, and a manufacturing method of the electronic modulation device according to some embodiments of the present invention. It should be understood that the following description provides many different embodiments or examples for implementing different aspects of some embodiments of the present invention. The specific components and arrangements described below are only for simply and clearly describing some embodiments of the present invention. Of course, these are only for illustration and not limitations of the present invention. In addition, repeated reference numerals or labels may be used in different embodiments. These repetitions are only for simply and clearly describing some embodiments of the present invention and do not represent any relevance between the different embodiments and / or structures discussed. Furthermore, when it is stated that a first material layer is on or above a second material layer, it includes the case where the first material layer is in direct contact with the second material layer. Or, there may also be a case where one or more other material layers are interposed, in which case the first material layer and the second material layer may not be in direct contact.
[0056] In addition, relative terms such as "lower" or "bottom" and "higher" or "top" may be used in the embodiments to describe the relative relationship of one component of the drawing to another component. It can be understood that if the device in the drawing is flipped upside down, the component described on the "lower" side will become the component on the "higher" side. Here, the terms "about", "approximately", "substantially" generally mean within 20% of a given value or range, such as within 10%, or within 5%, or within 3%, or within 2%, or within 1%, or within 0.5%. The given quantity is an approximate quantity, that is, the meaning of "about", "approximately", "substantially" can still be implied without specifically stating "about", "approximately", "substantially".
[0057] It should be noted that in the following text, the term "substrate" may include components formed on a transparent substrate and various film layers covering the substrate, and any required number of active components (transistor components) may be formed above it. However, for simplicity of the drawings here, only a flat substrate is shown.
[0058] Refer to Figure 1 , Figure 1 is a top view of an electronic modulation device 100 according to some embodiments of the present invention. As Figure 1 shown, the electronic modulation device 100 includes a working area 100A and a non-working area 100B. The working area 100A may include a working device 540 (shown in Figure 8A) The non-working area 100B can be adjacent to the working area 100A. The electronic modulation device 100 can include an integrated circuit, such as a microprocessor, a storage element, and / or other components. The electronic modulation device 100 can also include different passive and active components, and wires. The passive and active components can be, for example, thin film transistors, thin-film resistors, other types of capacitors such as metal-insulator-metal capacitors (MIMCAPs), inductors, diodes, Metal-Oxide-Semiconductor field-effect transistors (MOSFETs), complementary MOS transistors (CMOSFETs), bipolar junction transistors (BJTs), laterally diffused MOS transistors (LDMOSFETs), high-power MOS transistors, or other types of transistors.
[0059] Refer to Figure 2 , Figure 2 is Figure 1 an enlarged view of area A of the electronic modulation device 100. As Figure 2 shown, the working area 100A can include a plurality of first parts 10 and a plurality of second parts 20. In some embodiments, at least one working device 540 can be included in the first part 10. The first part 10 can be an M×N array, where M and N are both positive integers, but the present invention is not limited thereto. The second part 20 can be disposed adjacent to the first part 10, such as the area between two adjacent first parts 10, and can have any size and can be arranged in any manner. In some embodiments, the second part 20 may not have a working device 540. In some embodiments, an adjustment unit with a smaller restoring force per unit area (shown in Figure 3B ) is formed on the first part 10, and an adjustment unit with a larger restoring force per unit area (shown in Figure 3B ) is formed on the second part 20.
[0060] Returning to Figure 1 , the non-working area 100B can include a plurality of second parts 20, and the second parts 20 can have any size and can be arranged in any manner, and the present invention is not limited thereto.
[0061] Refer to Figure 3A , 3B , Figure 3A , 3B is a process flow chart of the electronic modulation device 100 according to some embodiments of the present invention.Figure 3A The cross-sectional view shown corresponds to Figure 2 a portion of the line R-R' of the working area 100A in Figure 3A As shown, a first substrate 102 is first provided. It should be noted that the first substrate 102 may include multiple layers and various components disposed within and / or on the multiple layers. For the sake of simplicity, only one layer is shown herein. The area of the first substrate 102 corresponding to the first portion 10 may have at least one working device 540 disposed on the first substrate 102. The area of the first substrate 102 corresponding to the second portion 20 may have no working device 540 disposed within the first substrate 102.
[0062] As Figure 3A shown, at least one adjustment unit 104 is disposed on the first portion 10 of the first substrate 102, and at least one adjustment unit 106 is disposed on the second portion 20 of the first substrate 102. In some embodiments, the materials of the adjustment unit 104 and the adjustment unit 106 include photoresist or other suitable materials, and the present invention is not limited thereto. In certain embodiments, in a top view direction, the adjustment unit 104 and / or the adjustment unit 106 may be elongated. The adjustment unit 104 and / or the adjustment unit 106 may be arranged along one or more directions, and there may be a gap between two adjacent adjustment units 104 and / or adjustment unit 106 to allow the material of the modulation material layer 110 (shown in Figure 3B ) to flow. In this embodiment, the adjustment unit 104 and the adjustment unit 106 may each be a spacer formed of photoresist. The adjustment unit 104 and the adjustment unit 106 may have a thickness H1. In the present invention, the thickness and / or height may be measured in the normal direction of the substrate 102 in the central region and may be a value at a single point or an average value of multiple points. In certain embodiments, the thickness and / or height may be measured as the maximum thickness or the maximum height. In some embodiments, the adjustment unit 104 has a first elastic coefficient K1, and the adjustment unit 106 has a second elastic coefficient K2, where the second elastic coefficient K2 is greater than the first elastic coefficient K1. Here, the elastic coefficient may be a spring constant, and its unit is Newton per meter (N / m). The elastic coefficient may also be Young's modulus, and its unit is Newton per square meter (N / m 2)。In this embodiment, the material of the adjustment unit 104 may be the same as that of the adjustment unit 106, but their densities may be different. In some embodiments, the density of the adjustment unit 106 may be greater than that of the adjustment unit 104, such that the elastic coefficient of the adjustment unit 106 is greater than that of the adjustment unit 104, but this is not limited thereto. In other embodiments, the materials of the adjustment unit 104 and the adjustment unit 106 may be different. For example, the adjustment unit 104 and the adjustment unit 106 may be formed of different types of photoresist, such that the adjustment unit 104 and the adjustment unit 106 may have different elastic coefficients, but this is not limited thereto. Other methods that can make the elastic coefficient of the adjustment unit 104 different from that of the adjustment unit 106 can also be used.
[0063] In some embodiments, a plurality of adjustment units 108 may be disposed on the first portion 10 and / or the second portion 20 of the first substrate 102. The material of the adjustment unit 108 includes photoresist or other suitable materials, and the present invention is not limited thereto. As Figure 3A shown, the adjustment unit 108 may have a thickness H2. In some embodiments, the adjustment unit 108 has a third elastic coefficient K3. The third elastic coefficient K3 may be greater than the second elastic coefficient K2. In some embodiments, at least one adjustment unit 108 may be disposed between the adjustment unit 104 and the adjustment unit 106. The adjustment unit 104 may be disposed between two adjacent adjustment units 108. The adjustment unit 106 may also be disposed between two adjacent adjustment units 108. As Figure 3A shown, there may be a thickness difference X1 between the adjustment unit 104 and the adjustment unit 108, and there may be a thickness difference X1 between the adjustment unit 106 and the adjustment unit 108.
[0064] In some embodiments, the adjustment unit 104, the adjustment unit 106, and the adjustment unit 108 have different sizes, such as having different areas or shapes of the upper surface, or different areas or shapes of the side surfaces.
[0065] Next, as Figure 3B shown, the second substrate 112 is disposed on the first substrate 102 such that the adjustment unit 104 and the adjustment unit 106 are compressed to form the electronic modulation device 100. As Figure 3B shown, the adjustment unit 104a, the adjustment unit 106a, and the adjustment unit 108 are disposed between the first substrate 102 and the second substrate 112. Moreover, the adjustment unit 104a, the adjustment unit 106a, and the adjustment unit 108 may generally have a thickness H2’, where the thickness H2’ may be less than or equal to H2. In certain embodiments, the electronic modulation device 100 may include a modulation material layer 110, and the modulation material layer 110 is disposed between the first substrate 102 and the second substrate 112. The material of the modulation material layer 110 may include liquid crystal or other suitable modulation materials.
[0066] It should be noted that the second substrate 112 may include multiple layers and various components disposed within and / or on the multiple layers, and for the sake of simplicity, it is only represented by one layer herein. In some embodiments, the second substrate 112 may include at least one flexible layer film, such that the second substrate 112 may have a concave-convex or inclined surface.
[0067] In some embodiments, the distance between the first substrate 102 and the second substrate 112 is substantially the same in different regions. For example, the distance between the first portion 10 of the first substrate 102 and the second substrate 112 is distance D1, and the distance between the second portion 20 of the first substrate 102 and the second substrate 112 is also distance D1. As Figure 3A 、 3B shown, there is a thickness difference X1 between the compressed adjustment unit 104a and the adjustment unit 104 before compression, and there is a thickness difference X1 between the compressed adjustment unit 106a and the adjustment unit 106 before compression. In this embodiment, the adjustment unit 108 is substantially not compressed. The compressed adjustment unit 104a and the adjustment unit 106a may individually have a first restoring force F1 and a second restoring force F2 (the restoring force may be, for example, an elastic force). The first restoring force F1 and the second restoring force F2 may satisfy Hooke's law, as represented by the following formula (1):
[0068] F = -KΔX Formula (1)
[0069] In Formula (1), K is the spring constant, ΔX is the compressed length or thickness, and the negative sign is because the restoring force may be opposite to the direction in which the adjustment unit is compressed or stretched.
[0070] In this embodiment, F1 = -K1X1, F2 = -K2X1. That is, the magnitude of the restoring force of the adjustment unit 104a may be substantially equal to K1X1, and the magnitude of the restoring force of the adjustment unit 106a may be substantially equal to K2X1. Since the compressed lengths of the adjustment unit 104a and the adjustment unit 106a are substantially equal, therefore, the magnitudes of the restoring forces of the adjustment unit 104a and the adjustment unit 106a may depend on the spring constants of the adjustment unit 104a and the adjustment unit 106a. Because the second elastic coefficient K2 of the adjustment unit 106a may be greater than the first elastic coefficient K1 of the adjustment unit 104a, the second restoring force F2 may be greater than the first restoring force F1. It should be noted that Figure 3B the illustrated second restoring force F2 and the first restoring force F1 are only schematic, and actually the directions of the restoring forces generated by the adjustment unit 104a and the adjustment unit 106a may not be limited to one direction only. In certain embodiments, the directions of the first restoring force F1 and the second restoring force F2 may be along the normal direction of the substrate 102. Additionally, since the compressed length of the adjustment unit 108 is substantially 0, the restoring force generated by the adjustment unit 108 is substantially 0.
[0071] Refer to Figure 4 , Figure 4 which is a cross-sectional schematic diagram of an electronic modulation device 100' according to some embodiments of the present invention. When the volume of the electronic modulation device 100 changes, it can become the electronic modulation device 100' as shown in Figure 4 . According to the above, the second restoring force F2 can be greater than the first restoring force F1. Therefore, the restoring force received by the second substrate 112 in the area corresponding to the second part 20 is greater than the restoring force received by the second substrate 112 in the area corresponding to the first part 10. As a result, the distance between the first substrate 102 and the second substrate 112 in the area corresponding to the first part 10 can be the distance Z1 plus the thickness H2, and the distance between the first substrate 102 and the second substrate 112 in the area corresponding to the second part 20 can be the distance Z2 plus the thickness H2. The distance Z1 plus the thickness H2 can be less than the distance Z2 plus the thickness H2. The distance Z1 can be less than the distance Z2. In other embodiments, at this time, the adjusting unit 104b has a thickness H3, and the adjusting unit 106b has a thickness H4. As shown in Figure 4 , the thickness H4 can be greater than the thickness H3. In this embodiment, the distance between the first part 10 of the first substrate 102 and the second substrate 112 is approximately the same as the thickness H3, and the distance between the second part 20 of the first substrate 102 and the second substrate 112 is approximately the same as the thickness H4.
[0072] In some cases, for example, when the electronic modulation device changes in volume due to heat, the second substrate 112 may be deformed, causing the distance between the first substrate 102 and the second substrate 112 to increase. As a result, it may cause the capacitance value in the electronic modulation device to change, affecting the performance of the electronic modulation device. In this embodiment, an adjusting unit 104 with a smaller elastic coefficient is provided in the first part 10 where the working device 540 is provided, and an adjusting unit 106 with a larger elastic coefficient is provided in the second part 20 where the working device 540 is not provided. As shown in Figure 4 , when the electronic modulation device changes in volume, for example, due to heat, the change in the distance between the first part 10 of the first substrate 102 and the second substrate 112 is smaller than the change in the distance between the second part 20 of the first substrate 102 and the second substrate 112. That is, the change in the spacing where the working device 540 is provided is smaller, which can make the working device 540 more stable under temperature change conditions, thereby improving the reliability of the electronic modulation device 100.
[0073] Various changes and adjustments can be made in the embodiments of the present invention. Refer to Figure 5A , 5B , Figure 5A , 5B which is a process flow chart of an electronic modulation device 200 according to some other embodiments of the present invention. Figure 5AThe structure shown can be the same as or similar to Figure 3A the structure shown, with one of the differences being that adjustment unit 104 is replaced by adjustment unit 204, and adjustment unit 106 is replaced by adjustment unit 206. In some embodiments, the materials of adjustment unit 204 and adjustment unit 206 can be substantially the same and can have substantially the same density. Thus, adjustment unit 204 and adjustment unit 206 can have substantially the same elastic coefficient. In some embodiments, adjustment unit 204 and adjustment unit 206 have a fourth elastic coefficient K4. As Figure 5A shown, adjustment unit 204 has a thickness H5, and adjustment unit 206 has a thickness H6, where thickness H6 can be greater than thickness H5. Additionally, adjustment unit 108 has a thickness X7 and can have a third elastic coefficient K3 greater than the fourth elastic coefficient K4. As Figure 5A shown, there is a thickness difference X3 between adjustment unit 204 and adjustment unit 108, and a thickness difference X4 between adjustment unit 206 and adjustment unit 108, and thickness difference X4 can be greater than thickness difference X3. In some embodiments, adjustment unit 204, adjustment unit 206, and adjustment unit 108 can have different sizes, such as having different areas or shapes of the upper surface, or different areas or shapes of the side surfaces.
[0074] Next, as Figure 5B shown, a modulation material layer 110 is filled on the first substrate 102, and a second substrate 112 is disposed on the first substrate 102 such that adjustment unit 204 and adjustment unit 206 are compressed to form an electronic modulation device 200. As Figure 5B shown, adjustment unit 204a, adjustment unit 206a, adjustment unit 108, and the modulation material layer 110 are disposed between the first substrate 102 and the second substrate 112. And adjustment unit 204a, adjustment unit 206a, adjustment unit 108 can generally have a thickness H7', where thickness H7' can be less than or equal to thickness H7.
[0075] In some embodiments, in the electronic modulation device 200, the distance between the first substrate 102 and the second substrate 112 is substantially the same in different regions. For example, the distance between the first part 10 of the first substrate 102 and the second substrate 112 is distance D2, and the distance between the second part 20 of the first substrate 102 and the second substrate 112 is also distance D2. As Figure 5A 、 5BAs shown, there is a thickness difference X3 between the compressed adjustment unit 204a and the adjustment unit 204 before compression, and there is a thickness difference X4 between the compressed adjustment unit 206a and the adjustment unit 206 before compression. The adjustment unit 108 may be substantially uncompressed. The compressed adjustment unit 204a and the adjustment unit 206a may individually have a third restoring force F3 and a fourth restoring force F4. The third restoring force F3 and the fourth restoring force F4 may satisfy Hooke's law. In this embodiment, F3 = -K4X3, F4 = -K4X4. That is, the magnitude of the restoring force of the adjustment unit 204a may be substantially equal to K4X3, and the magnitude of the restoring force of the adjustment unit 206a may be substantially equal to K4X4. Since the elastic coefficients of the adjustment unit 204a and the adjustment unit 206a may be substantially equal, the magnitudes of the restoring forces of the adjustment unit 204a and the adjustment unit 206a may depend on the compressed lengths of the adjustment unit 204a and the adjustment unit 206a. Since the thickness difference X4 may be greater than the thickness difference X3, the fourth restoring force F4 may be greater than the third restoring force F3. It should be noted that Figure 5B The illustrated fourth restoring force F4 and third restoring force F3 are only schematic. In fact, the directions of the restoring forces generated by the adjustment unit 204a and the adjustment unit 206a may not be limited to only one direction. In some embodiments, the directions of the third restoring force F3 and the fourth restoring force F4 may be along the normal direction of the substrate 102.
[0076] Refer to Figure 6 , Figure 6 is a cross-sectional schematic view of an electronic modulation device 200' according to some embodiments of the present invention. When the electronic modulation device 200 expands, it can become like Figure 6 shown in the electronic modulation device 200'. According to the above, the fourth restoring force F4 may be greater than the third restoring force F3. Therefore, the restoring force received by the second substrate 112 in the area corresponding to the second part 20 may be greater than the restoring force received by the second substrate 112 in the area corresponding to the first part 10. As a result, the distance between the first substrate 102 and the second substrate 112 in the area corresponding to the first part 10 may be the distance Z3 plus the thickness H7, and the distance between the first substrate 102 and the second substrate 112 in the area corresponding to the second part 20 may be the distance Z4 plus the thickness H7. The sum of the distance Z3 plus the thickness H7 may be less than the sum of the distance Z4 plus the thickness H7. The distance Z3 may be less than the distance Z4. At this time, the adjustment unit 204b may have a thickness H8, and the adjustment unit 206b may have a thickness H9. As Figure 6 shown, the thickness H9 may be greater than the thickness H8. In this embodiment, the distance between the first part 10 of the first substrate 102 and the second substrate 112 may be substantially the same as the thickness H8, and the distance between the second part 20 of the first substrate 102 and the second substrate 112 may be substantially the same as the thickness H9, where the thickness H9 may be greater than the thickness H8.
[0077] The adjustment unit 204 and the adjustment unit 206 can be variously changed and adjusted in the embodiments of the present invention. Refer to Figure 7 , Figure 7 FIG. 5 is a cross-sectional schematic view of an electronic modulation device 300 according to some embodiments of the present invention. The electronic modulation device 300 is the same as or similar to the electronic modulation device 100. One of the differences is that the adjustment unit 104 is replaced by an adjustment unit 304, and the adjustment unit 106 is replaced by an adjustment unit 306. As Figure 7 shown, the adjustment unit 304 includes a plurality of spacers 308. The adjustment unit 306 includes a plurality of spacers 310. The materials of the spacer 308 and the spacer 310 can be individually the same as or similar to those of the adjustment unit 104 and the adjustment unit 106, and will not be elaborated here. In other embodiments, the material of the spacer 308 can be different from the material of the spacer 310. Figure 7 FIG. 9 shows that the adjustment unit 304 includes two spacers 308, and the adjustment unit 306 includes two spacers 310. In other embodiments, the adjustment unit 304 can include at least one spacer 308, and the adjustment unit 306 can include at least one spacer 310. The number of spacers 308 per unit area can also be different from the number of spacers 310 per unit area in the above. For example, the number of spacers 308 per unit area can also be greater than or less than the number of spacers 310 per unit area in the above. The unit area can be, for example, a rectangular area of 5 cm by 5 cm, a rectangular area of 3 cm by 3 cm, a rectangular area of 1 cm by 1 cm, or other appropriate areas, but not limited thereto. In this embodiment, the second substrate 112 is subjected to two first restoring forces F1 corresponding to the first part 10, and two second restoring forces F2 corresponding to the second part 20.
