This abstract first appeared for US patent application 20250133839 titled 'PIXEL AND IMAGE SENSOR INCLUDING THE SAME
Original Abstract Submitted
an image sensor includes a plurality of pixels, wherein each of the plurality of pixels includes a first epitaxial layer disposed on a first surface of a semiconductor substrate and formed to have a first conductive type by an epitaxial growth process, a photoelectric conversion device disposed on the first epitaxial layer, the photoelectric conversion device having a second conductive type which differs from the first conductive type and a second epitaxial layer disposed between the photoelectric conversion device and a second surface of the semiconductor substrate and formed to have the second conductive type through the epitaxial growth process, wherein the photoelectric conversion device is an epitaxial layer of the second conductive type formed by the epitaxial growth process.
