System and method to improve image sensor sensitivity
摘要:
A method is disclosed for forming at least one image sensor with improved sensitivity along with at least one transistor device. The method comprises forming at least a portion of the transistor device on a substrate, forming the image sensor by doping a predetermined area separated from the transistor device by a minimum predetermined distance, forming an etch stop layer for covering a contact area of the transistor device, removing at least a portion of the etch stop layer in the predetermined area for exposing the image sensor, and covering the image sensor and the transistor device by at least one transparent protection layer.
