发明名称 METHOD FOR REDUCING CROSSTALK IN CMOS IMAGE SENSOR
摘要 A method of manufacturing a CMOS image sensor includes providing a semiconductor substrate having a front side and a back side, forming at least two pixels in the front side, forming a shallow trench isolation in the front side between the at least two pixels, forming a deep trench in the back side at a location above the shallow trench isolation, and depositing a dielectric layer in the deep trench to form a crosstalk reduction element.
