Solid state imaging device with semiconductor imaging and processing chips
The present invention provides a small, high-performance imaging device and its application to products at low cost by preventing noise superimposed on a timing pulse feed line from affecting the output of an imaging chip. The imaging device includes two chips: an imaging chip 101 including a sensor 102 and an image processing chip 106 including an image processing circuit 110. The transistors of all circuits in the imaging chip 101 are formed as either nMOS or pMOS transistors. The imaging chip 101 is stacked on the image processing chip 106.
