摘要: A CMOS image sensor obtains color through the use of two or three superposed layers. Each pixel in the image sensor includes a plurality of superposed photosensitive p-n junctions with individual charge integration regions. The combination of each of the superposed layers provides increased sensitivity and resolution of a single chip color imager.

摘要: A fully depleted photodiode accumulates charge into both the diode and a separate floating diffusion. The floating diffusion has less capacitance that the overall diode, thereby resulting in a knee-shaped transfer characteristic for charge accumulation. The fully depleted photodiode also include two PN junctions, one near the surface and the other buried below the surface.
