摘要： A method of operation of a backside illuminated (BSI) pixel array includes acquiring an image signal with a first photosensitive region of a first pixel within the BSI pixel array. The image signal is generated in response to light incident upon a backside of the first pixel. The image signal acquired by the first photosensitive region is transferred to pixel circuitry of the first pixel disposed on a frontside of the first pixel opposite the backside. The pixel circuitry at least partially overlaps the first photosensitive region of the first pixel and extends over die real estate above a second photosensitive region of a second pixel adjacent to the first pixel such that the second pixel donates die real estate unused by the second pixel to the first pixel to accommodate larger pixel circuitry than would fit within the first pixel.

摘要： An image sensor includes a color filter array, sense amplifiers, multiplexing circuitry, and an output. The color filter array acquires image data using an array of M columns and N rows of pixels. The sense amplifiers are coupled to the color filter array for reading out image data from the color filter array. The multiplexing circuitry couples the sense amplifiers to the color filter array, wherein each sense amplifier is time shared across multiple columns and multiple rows. The output is coupled to receive the image data from the sense amplifiers and output the image data off-chip.

摘要： An image sensor that has a pixel array using an isolation structure between pixels that reduce electrical cross-talk is disclosed. The pixel array is formed on a substrate that has a thin (less than 5 microns) epitaxial layer. The isolation structure uses a deep p-well to surround a shallow trench isolation. The deep p-well is formed using an implant energy of typically over 700 keV.
