Abstract
Various embodiments of the present disclosure are directed towards a stacked complementary metal-oxide semiconductor (CMOS) image sensor in which a pixel sensor spans multiple integrated circuit (IC) chips and has only a first gate dielectric thickness at a first IC chip at which a photodetector of the of the pixel sensor is arranged. Further, the pixel sensor has only one or more second gate dielectric thicknesses at a second IC chip that is stacked with the first IC chip, and the one or more second gate dielectric thicknesses is/are less than or equal to the first gate dielectric thickness. The first and second gate dielectric thicknesses correspond to transistors of the pixel sensor, which form a pixel circuit of the pixel sensor configured to facilitate readout of the photodetector.
