摘要:
A semiconductor device is manufactured through steps in which a photoelectric conversion element and an amplifier circuit are formed over a first substrate with a release layer interposed therebetween, and the photoelectric conversion element and the amplifier circuit are separated from the first substrate. Output characteristics of the amplifier circuit are improved and the semiconductor device with high reliability is obtained. A manufacturing method of such semiconductor device includes steps of forming a metal layer having an opening portion over a substrate, forming an insulating layer over the entire surface of the substrate including the opening portion and the metal layer, forming a photoelectric conversion layer in a region which overlaps with the metal layer and is a layer over the insulating layer, forming an amplifier circuit, which amplifies an output current of the photoelectric conversion element by using a thin film transistor, in the opening portion in the metal layer, forming a protective layer over the photoelectric conversion element and the amplifier circuit, and separating the photoelectric conversion element and the amplifier circuit, together with the insulating layer, from the substrate through laser irradiation to the metal layer.

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.

A serial signal transmission device and a control method for determining polarity which can be used in various systems, for example, air conditioners, and a remote controller. The serial signal transmission device which carries out signal transmission between a plurality of control devices uses two transmission wires with fixed polarity, the serial transmission interface of each control device is equipped with two pairs of differential drivers and receivers, and the driver outputs and receiver inputs of different polarity in these two pairs of drivers and receivers are connected to each other. This device and control method make connection terminals for signal lines on each control device nonpolar, considerably reducing workload required for installing the apparatuses and wiring and eliminating connection errors.
