The terminal to which the high potential is applied is called the drain, and the terminal to which the high potential is applied is called the source. For convenience, let us assume that the source and drain are fixed. In some cases, the connection relationship between the source and drain is explained, but in reality, the connection between the source and drain is determined according to the above potential relationship.

Therefore, the connected state corresponds to a state in which the does not necessarily refer to the state in which a current, voltage or potential is available or transferable. The signals are transmitted through circuit elements such as wiring, resistors, diodes, and transistors. This also includes the state of being directly connected.

[0048] In this specification, even if components that are independent on the circuit diagram are connected to each other, However, in reality, for example, when a part of a wiring functions as an electrode, one conductive film may be connected to multiple In this specification, the term "connection" refers to such a connection. Cases in which one conductive film has the functions of multiple components are also included in this category.

[0202] In addition, in the CAC-OS or CAC-metal oxide, the conductive region and the insulating region are The peripheral region is 0.5 nm to 10 nm, preferably 0.5 nm to 3 nm. The following sizes may be present in the material:

[0203] In addition, CAC-OS or CAC-metal oxide has different band gaps. For example, CAC-OS or CAC-metal oxi de is a component with a wide gap due to the insulating region and a component with a narrow gap due to the conductive region. In the case of this configuration, when a carrier flows, In the narrow gap component, carriers mainly flow. The component having a narrow gap acts complementary to the component having a wide gap. Carriers also flow to the wide gap component in conjunction with the component with a large gap. AC-OS or CAC-metal oxide is placed in the channel formation region of the transistor. When used, the transistor has a high current driving force in the on-state, i.e., a large on-current. And high field effect mobility can be obtained.

[0204] That is, CAC-OS or CAC-metal oxide is a matrix composite material. (matrix composite) or metal matrix composite (metal matrix It can also be called atrix composite.

[0205] For example, the elements constituting the metal oxide in the CAC-OS are 0.5 nm or more and 10 nm or less. Preferably, the material is unevenly distributed in a size range of 1 nm to 2 nm or in the vicinity thereof. In the following, it is assumed that one or more metal elements are unevenly distributed in a metal oxide. The region having the metal element has a size of 0.5 nm to 10 nm, preferably 1 nm to 2 nm. A mixed state in which the size is less than or close to one m is also called a mosaic or patch pattern.

[0206] The metal oxide preferably contains at least indium. It is preferable that the metal contains zinc. In addition to the above, aluminum, gallium, yttrium, Aluminum, copper, vanadium, beryllium, boron, silicon, titanium, iron, nickel, germanium nium, zirconium, molybdenum, lanthanum, cerium, neodymium, hafnium, tantalum One or more of the following are included: tungsten, magnesium, etc. It's fine.

[0207] For example, CAC-OS made of In-Ga-Zn oxide (In-Ga-Zn oxide is one of the CAC-OS) a-Zn oxide may be specifically referred to as CAC-IGZO. (Hereinafter, InO X1 (X1 is a real number greater than 0.) or indium zinc oxide compound (hereinafter referred to as In X2 Zinc Y2 O Z2 (X2, Y2, and Z2 are real numbers greater than 0) ) and gallium oxide (GaO X3 (X3 is a real number greater than 0). ), or gallium zinc oxide (Ga X4 Zinc Y4 O Z4 (X4, Y4, and Z4 (is a real number greater than 0).) The material is separated into a mosaic shape, Mosaic InO X1 , or In X2 Zinc Y2 O Z2 is uniformly distributed in the film (Hereinafter, this will also be referred to as cloud-like.)

[0208] In other words, CAC-OS is X3The region where In is the main component and X2 Zinc Y2 O Z2 , or InO X1 A composite metal oxide having a structure in which a region in which In this specification, for example, the atomic ratio of In to the element M in the first region is The first region has an atomic ratio of In to the element M in the second region that is greater than the atomic ratio of In in the second region. The concentration of In is higher than in the region

[0209] Note that IGZO is a common name and refers to a compound made of In, Ga, Zn, and O. A typical example is InGaO3(ZnO). m1 (m1 is a natural number), or In (1 +x0) Ga (1-x0) O3(ZnO) m0 (-1≦x0≦1, m0 is an arbitrary number) Examples of such crystalline compounds include those that are

[0210] The crystalline compounds may have a single crystal structure, a polycrystalline structure, or a c-axis aligned crystal structure (CAAC). The CAAC structure is a structure in which multiple IGZO The nanocrystals have a c-axis orientation and are connected in ab-plane without being oriented. do.

[0211] On the other hand, CAC-OS is a material structure of metal oxide. CAC-OS is a material structure of In, Ga In the material composition containing Zn, and O, nanoparticles mainly composed of Ga were observed in some parts. The regions where the In is mainly contained are observed as nanoparticles, and the regions where the In is mainly contained as nanoparticles are observed. Therefore, in the CAC-OS, the crystal structure is a secondary element.

[0212] It should be noted that the CAC-OS does not include a laminated structure of two or more films having different compositions. For example, a structure consisting of two layers, a film mainly made of In and a film mainly made of Ga, is not included. do not have.

[0213] In addition, GaO X3 The region where In is the main component and X2 Zinc Y2 O Z2 , or InO X1 but In some cases, a clear boundary between the region of the main component and the region of the main component may not be observed.

[0214] Instead of gallium, aluminum, yttrium, copper, vanadium, and beryllium can be used. , boron, silicon, titanium, iron, nickel, germanium, zirconium, molybdenum , lanthanum, cerium, neodymium, hafnium, tantalum, tungsten, or magnesium If one or more selected types of sodium, etc. are included, CAC-OS will The region observed is a nanoparticle of the metal element as the main component, and the region observed is a nanoparticle of In as the main component. The nanoparticle-like regions are randomly distributed in a mosaic pattern. say.

[0215] CAC-OS is formed by sputtering without intentionally heating the substrate. In addition, when the CAC-OS is formed by a sputtering method, the deposition gas and The gas to be used should be selected from an inert gas (typically argon), oxygen gas, and nitrogen gas. In addition, the ratio of oxygen gas to the total flow rate of the deposition gas during deposition may be For example, the flow rate ratio of oxygen gas is preferably 0% or more and less than 30%. It is preferable that the content be 0% or more and 10% or less.

[0216] CAC-OS is a type of X-ray diffraction (XRD) measurement method. When measured using the θ / 2θ scan by the out-of-plane method, In other words, the analysis results by X-ray diffraction show that no clear peaks are observed. From this, it can be seen that no orientation in the ab plane direction or the c-axis direction is observed in the measurement area.

[0217] In addition, the CAC-OS uses an electron beam with a probe diameter of 1 nm (also called a nano-beam electron beam). In the electron diffraction pattern obtained by irradiating the sample with electrons, a ring-shaped area of ​​high brightness (ring In the ring region, multiple bright spots are observed. Therefore, from the electron diffraction pattern, The crystal structure of CAC-OS is nc( It can be seen that the material has a nano-crystal structure.

[0218] For example, in the case of CAC-OS made of In-Ga-Zn oxide, energy dispersive X-ray Spectroscopy (EDX: Energy Dispersive X-ray spectroscopy) The EDX mapping obtained using a GaO X3 The region where is the main component and , In X2 Zinc Y2 O Z2 , or InO X1 The areas where the main component is It can be confirmed that the compound has the structure shown in FIG.

[0219] CAC-OS has a structure different from that of IGZO compounds in which metal elements are uniformly distributed. It has different properties from ZO compounds. That is, CAC-OS is GaO X3 The main ingredients are In a certain area,X2 Zinc Y2 O Z2 , or InO X1 The region where is the main component and The phase is separated into two layers, and the regions each containing one element as a main component are arranged in a mosaic pattern.

[0220] Here, In X2 Zinc Y2 O Z2 , or InO X1 The area where GaO is the main component X3 This region has a higher electrical conductivity than the region where In is the main component. X2 Zinc Y 2O Z2 , or InO X1 The carriers flow through the area where the main component is oxidized. Therefore, the conductivity of In is expressed as a semiconductor. X2 Zinc Y2 O Z2 , or InO X The region where 1 is the main component is distributed in a cloud-like shape in the oxide semiconductor, which results in a high electric field effect. Mobility (μ) can be achieved.

[0221] On the other hand, GaO X3 The region where the main components are In X2 Zinc Y2 O Z2 , or InO X This region has higher insulating properties than the region where GaO X3 etc. The distribution of the main component in the oxide semiconductor suppresses leakage current and provides good switching performance. Switching operation can be achieved.

[0222] Therefore, when CAC-OS is used in a semiconductor device, GaO X3 Insulation caused by In X2 Zinc Y2 OZ2 , or InO X1 The conductivity caused by the This results in a high on-state current (I on ) and high field-effect mobility (μ) can be achieved. Cut.

A method of supplying a selection signal to one scanning line at a time and displaying based on the selection signal is called the second mode. It can be associated with a

[0316] A selection signal at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute. By supplying the above, it is possible to suppress flicker or blinking when displaying. Power consumption can be reduced.

[0317] For example, when the information processing device 200 is used in a clock, the frequency is once per second or once per minute. The display can be updated with frequency, etc.

[0318] By the way, when a light emitting element is used as a display element, the light emitting element is made to emit light in a pulsed manner. Specifically, the organic EL element is made to emit light in a pulsed manner, so that image information can be displayed. The afterglow can be used for display. Organic EL elements have excellent frequency characteristics. In this case, the time for driving the light-emitting element can be shortened, and power consumption can be reduced. In this case, heat generation is suppressed, and therefore deterioration of the light-emitting element can be reduced in some cases.

[0319] [Fourth step] In the fourth step, if a termination command is provided, the process proceeds to the fifth step. If not supplied, select to proceed to the third step (FIG. 14(A)(S4) reference).

[0320] For example, the end command supplied in the interrupt process may be used for the judgment.

[0321] [5th ​​step] In the fifth step, the process ends (see FIG. 14(A)(S5)).

[0322] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 14(B)). .

[0323] [Sixth step] In a sixth step, for example, the detection unit 250 is used to detect whether the information processing device 200 is being used. The illuminance of the environment in which the subject is placed is detected (see FIG. 14(B)(S6)). The color temperature and chromaticity of the ambient light may also be detected.

[0324] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (FIG. 14(B) ) (see S7)). For example, the brightness of the display should be adjusted to ensure it is not too dark or too bright. is decided.

[0325] In addition, if the color temperature or chromaticity of the ambient light is detected in the sixth step, the display The color may be adjusted.

[0326] [8th step] In the eighth step, the interrupt process ends (see FIG. 14(B) (S8)).

[0327] <Configuration example 3 of information processing device> Another configuration of the information processing device of one embodiment of the present invention will be described with reference to FIG.

[0328] FIG. 15A is a flowchart illustrating a program according to one embodiment of the present invention. (A) is a flow chart explaining an interrupt process different from the interrupt process shown in FIG. 14(B). It is a chart.

[0329] In addition, the third example of the information processing device changes the mode based on a given event. The fact that the interrupt process includes a step for performing the above-mentioned operation is the same as that of the interrupt process described with reference to FIG. This section describes the differences in detail and explains how to use a similar configuration. The above explanation will be used to explain the parts that can be used.

[0330] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 15(A)). .

[0331] [Sixth step] In the sixth step, if a predetermined event is provided, the seventh step is performed; If the predetermined event is not provided, proceed to the eighth step (FIG. 15(A)(U6 For example, a condition can be whether a specific event was provided within a specific period of time. Specifically, it is possible to perform the above-mentioned operation for 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less. The predetermined period may be a period longer than 0 seconds.

[0332] [Seventh step] In the seventh step, the mode is changed (see FIG. 15(A)(U7)). Specifically, If you have selected the first mode, select the second mode, and then select the second mode. If so, the first mode is selected.

[0333] For example, the display mode of a part of the display unit 230 can be changed. Specifically, the display unit 230 includes the drive circuits GDA, GDB, and GDC. The display mode can be changed for an area to which one drive circuit supplies a selection signal ( See Figure 15(B).

[0334] For example, in the input section 240 in the area overlapping the area where the driving circuit GDB supplies the selection signal, When a specific event is supplied, the driver GDB supplies a selection signal to the display model of the area. The mode can be changed (see Fig. 15(B) and Fig. 15(C)). The driver circuit GDB supplies a "tap" event to the touch panel using the The frequency of the selection signal can be changed.

[0335] The signal GCLK is a clock signal that controls the operation of the driving circuit GDB, and the signal PWC Signals PWC1 and PWC2 are pulse width control signals that control the operation of the driver circuit GDB. The circuit GDB outputs a selection signal based on the signals GCLK, PWC1 and PWC2. are supplied to the scanning lines G1(m+1) to G1(2m).

[0336] This allows, for example, the driver circuits GDA and GDC to supply a selection signal. Alternatively, the driver circuit GDA and the driver circuit GDB may supply the selection signal. The driver circuit GDB selects the area without changing the display of the area to which the driver circuit GDC supplies the selection signal. The display of the area to which the select signal is supplied can be updated. can be suppressed.

[0337] [8th step] In the eighth step, the interrupt process is ended (see FIG. 15(A)(U8)). Alternatively, the interrupt process may be repeatedly executed during the execution of the main process.

[0338] 《Specified Event》 For example, "clicking" and "dragging" provided using a pointing device such as a mouse Events such as "tap" and "drag" are supplied to the touch panel using a finger as a pointer. Events such as "click" or "swipe" can be used.

[0339] Also, for example, the position of the slide bar pointed to by the pointer, the speed of the swipe, the speed of the drag, The degree or the like can be used to provide arguments for the command associated with a given event.

[0340] For example, the information detected by the detection unit 250 is compared with a preset threshold value, and the comparison result is can be used for events.

[0341] Specifically, a pressure-sensitive detector that contacts a button or the like that is arranged so that it can be pressed into the housing. etc. can be used for the detection unit 250.

[0342] Commands associated with specific events For example, a termination command may be associated with a particular event.

[0343] For example, a "page turn" function is used to switch the display from one image to another. The "page turn command" can be associated with a specific event. The arguments that determine the page turning speed and other parameters used during execution are sent using a specified event. Can be given.

[0344] For example, the display position of a part of one image information is moved to display a part of the image information that is continuous with the part. You can associate a "scroll command" to display other parts with a specified event. In addition, it determines the speed at which the display moves when executing the "scroll command." Arguments can be provided with a given event.

[0345] For example, a command to set a display method or a command to generate image information is generated by a predetermined event. It is possible to associate the argument that determines the brightness of the generated image with a given event. In addition, the argument that determines the brightness of the generated image can be associated with the detection unit 2. The determination may be based on the brightness of the environment detected by 50.

[0346] For example, information distributed using a push-type service is acquired using the communication unit 290. An instruction to execute a command or the like can be associated with a given event.

[0347] The qualification to obtain information is determined using the location information detected by the detection unit 250. Specifically, the person may be in a specific classroom, school, conference room, company, building, or other area. This may allow, for example, a school or The information processing device 200 can be used as a textbook or the like by receiving teaching materials distributed in classrooms at universities, etc. (See Figure 13(C)). Or, you can receive materials distributed in a conference room of a company, etc. , can be used for meeting materials.
