Problems solved by technology

[0032] The present application proposes an image sensing device, which uses a microprism to modify an incident light angle with a relatively large angle to an incident light angle with a small angle, which can eliminate the brightness difference caused by the deviation of the main incident light angle ( Optical crosstalk effect caused by excessive deviation between shading) and incident chief light angle and solve the problem of uneven layout of photosensitive elements

Description

technical field [0001] The invention relates to a photoelectric product related to microelectronics, in particular to a structure and stacking method of an image sensing device related to microelectronics. Background technique [0002] ■Structure of image sensor [0003] With the rapid development of optoelectronic products, the demand for image sensors continues to increase. At present, general image sensors are divided into two categories, namely, CCD (Charge Coupled Device, Charge Coupled Device) image sensors and CMOS (Complementary Metal-Oxide Semiconductor, Complementary Metal-Oxide Semiconductor) image sensors. [0004] An image sensor is used to record light changes of an image, and then convert the light into electronic signals, which are recorded and interpreted by the processing chip, and then restored to an image for output, reproduction or storage. The image sensor is composed of a large number of photosensitive elements, and the photosensitive elements are us...
