Problems solved by technology

[0009] However, in the case of a structure in which the substrate of the pixel portion 11 and the substrate of the circuit portion 31 are stacked on each other in this way, heat generated in the circuit portion 31 exerts a bad influence on the pixel portion 11, whereby in some cases degrade the video signal
As a result, circuitry must be provided to compensate for such situations, which leads to increased costs in some cases
If the circuit for compensation is omitted, it becomes difficult to provide a high-quality image sensor

Embodiment Construction

[0054] figure 2 is a block diagram showing a semiconductor device according to an embodiment of the present technology. A semiconductor device 101 usable as, for example, a CMOS image sensor (Complementary Metal Oxide Semiconductor Image Sensor) used in a digital camera includes a pixel portion 111 . A plurality of pixels that detect light from a subject are arranged in an n×m matrix in the pixel portion 111 . For convenience, in figure 2 Only two pixels are shown in .

[0055] Each pixel is composed of transistors 151 to 153 , and a photodiode 154 . The photodiode 154 outputs a video signal obtained by photoelectrically converting light from a subject. Transistor 152 transmits the video signal from photodiode 154 to transistor 153 . The transistor 153 amplifies the video signal supplied thereto from the photodiode 154 through the transistor 152 and outputs the resulting video signal to the line 155 . Transistor 151 selects the photodiode 154 to be driven.
