    摘要: In a semiconductor device, where, with respect to a parasitic resistor in a current mirror circuit, a compensation resistor for compensating the parasitic resistor is provided in the current mirror circuit, the current mirror circuit includes at least two thin film transistors. The thin film transistors each have an island-shaped semiconductor film having a channel formation region and source or drain regions, a gate insulating film, a gate electrode, and source or drain electrodes, and the compensation resistor compensates the parasitic resistor of any one of the gate electrode, the source electrode, and the drain electrode. In addition, each compensation resistor has a conductive layer containing the same material as the gate electrode, the source or drain electrodes, or the source or drain regions.

    摘要: It is an object to provide a photoelectric conversion device which detects light ranging from weak light to strong light. The present invention relates to a photoelectric conversion device having a photodiode having a photoelectric conversion layer, an amplifier circuit including a thin film transistor and a bias switching means, where a bias which is connected to the photodiode and the amplifier circuit is switched by the bias switching means when intensity of incident light exceeds predetermined intensity, and accordingly, light which is less than the predetermined intensity is detected by the photodiode and light which is more than the predetermined intensity is detected by the thin film transistor of the amplifier circuit. By the present invention, light ranging from weak light to strong light can be detected.

    摘要: A plurality of transistors in which ratios of a channel length L to a channel width W, α=W/L, are different from each other is provided in parallel as output side transistors 105a to 105c in a current mirror circuit 101 which amplifies a photocurrent of a photoelectric conversion device and an internal resistor is connected to each of the output side transistors 105a to 105c in series. The sum of currents which flow through the plurality of transistors and the internal resistor is output, whereby a transistor with large amount of α can be driven in a linear range with low illuminance, and a transistor with small amount of α can be driven in a linear range with high illuminance, so that applicable illuminance range of the photoelectric conversion device can be widened.

    摘要: The present invention has a photodiode and a circuit used to amplify the output of the photodiode. Two terminals are formed over the photodiode and circuit with an insulating layer interposed therebetween, and a dummy electrode with a larger area than that of either of the two terminals is formed thereover, adjacent to the two terminals. The dummy electrode is not connected to the photodiode or to the circuit of the semiconductor device. Because the dummy electrode has a wide area, damage due to electrostatic discharge occurs in the dummy electrode more easily than in the two terminals; thus, damage due to electrostatic discharge can be prevented from occurring in the semiconductor device.
