Abstract
Disclosed is a CMOS image sensor that includes pixels employing a radiation-sensitive resistive element in which the resistance of the element changes in response to the quantity of radiation striking it. The resistive elements are made from an appropriately doped polycrystalline semiconductor material such as polysilicon. The pixels are provided on a semiconductor device in which the photosensitive resistive elements are provided on a first layer and the pixel associated transistors are provided on a second layer. The fill factor may be approach 100 percent for such pixels.
