摘要:
An electronic apparatus comprising a material having photoconductivity, an energy bandgap, and trap levels. The material is typified by a thin film of polycrystalline diamond. The material is illuminated with a first electromagnetic emission, (which may include visible light, ultraviolet light, gamma rays, or x-rays) having photon energies smaller than the energy bandgap of the material. Then, the material is illuminated with a second electromagnetic emission having photon energies greater than the energy bandgap of the material to thereby induce a photocurrent. The amount of the first emission can be known by measuring the induced photocurrent.

摘要:
A thermistor layer made of platinum is formed on a thin diamond film. An amount of heat carried away from the diamond film by a fluid is detected as a change in the temperature of the thermistor layer. The rear side of the diamond film is kept in contact with the fluid to prevent the material of the thermistor from being corroded by the fluid. In another aspect of the invention, a heating element and a thermistor are formed on one surface of a thin diamond film. The other surface is kept in contact with a fluid. The diamond film is heated by the heating element in a quite short time of about 0.2 second. The resulting response characteristics of the diamond film are detected by the thermistor. The flow rate is calculated from the response characteristics.

The present invention provides an active matrix type display device having a high aperture ratio and a required auxiliary capacitor. A source line and a gate line are overlapped with part of a pixel electrode. This overlapped region functions to be a black matrix. Further, an electrode pattern made of the same material as the pixel electrode is disposed to form the auxiliary capacitor by utilizing the pixel electrode. It allows a required value of auxiliary capacitor to be obtained without dropping the aperture ratio. Also, it allows the electrode pattern to function as a electrically shielding film for suppressing the cross-talk between the source and gate lines and the pixel electrode.

In a structure in which six active matrix regions 103 to 108 are integrated on one glass substrate, horizontal scanning control circuits 101 and 102 are commonly disposed for the respective active matrix regions 103 to 105 and 106 to 108. Then the horizontal scanning control circuits 101 and 102 are operated at different timings, and images formed by the active matrix regions 103 to 105 and 106 to 108 are synthesized and projected. With this operation, the horizontal scanning frequency required for one horizontal scanning control circuit can be made half of the horizontal scanning frequency of the display screen.

In a monolithic active matrix circuit formed on a substrate, the active regions of at least a part of the thin film transistors (TFTs) constituting the peripheral circuit for driving the matrix region are added with a metal element for promoting the crystallization of silicon at a concentration of 1×1016 to 5×1019 cm−3, no metal element is added to the active region of the TFTs for the matrix region. The channel forming regions of at least a part of the TFTs constituting the peripheral circuit and the channel forming regions of the TFTs for the matrix region are formed by a silicon semiconductor thin film having a monodomain structure.
