Abstract

The embodiment of the present application discloses a method for forming an image sensor, an image sensor and electronic equipment, wherein the method includes: obtaining a pixel wafer substrate with a dielectric layer; layers of image sensors.

Description

technical field [0001] Embodiments of the present application relate to the field of semiconductor devices and their manufacture, and relate to, but are not limited to, a method for forming an image sensor, an image sensor, and electronic equipment. Background technique [0002] Image sensors are devices that convert light signals into electrical signals. In recent years, with the rapid development of the computer and communication industries, the range of applications for image sensors has gradually increased in various devices such as digital cameras, camcorders, game consoles, security cameras, medical miniature cameras, and robots, and There is also greater demand for the performance of image sensors. However, the problem of signal crosstalk between image sensor pixel units is one of the main factors affecting the performance of image sensors. [0003] At present, in order to reduce signal crosstalk between pixel units of an image sensor, two adjacent pixel units are g...
