Abstract

The invention provides a semiconductor structure, a method for forming an image sensor, an image sensor chip and an image sensor. The semiconductor structure comprises a substrate comprising a plurality of discrete chip regions, each of the chip regions comprises more than four discrete device regions, each of the device regions comprises a pixel array unit, and at least two pixel array units in each of the chip regions are adjacent to each other. The yield of the image sensor is improved by the semiconductor structure.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a semiconductor structure, a method for forming an image sensor chip, an image sensor chip and an image sensor. Background technique [0002] In the field of semiconductor technology, an image sensor is a functional device that converts an optical image into an electrical signal. Image sensors can be roughly classified into charge coupled devices (charge coupled device, CCD) and complementary metal oxide semiconductor image sensors (CMOS Image Sensor, CIS). [0003] At present, CCD is the main practical solid-state image sensor device, which has the advantages of low reading noise, large dynamic range and high response sensitivity. CMOS image sensors are widely used in digital cameras, camera phones, digital video cameras, medical imaging devices (such as gastroscopes), automotive In the field of camera equipment and so on. [0004] However, the chip of the image sensor...
