Abstract:
1. A method for manufacturing an image sensing device, comprising the steps of: providing a substrate; forming a photo sensor on said substrate by a first IC process; forming an IC stacking layer on said photo sensor by a second IC process; forming a micro prism on said IC stacking layer by a first integrated optical process, wherein said micro prism has an inclined angle, said inclined angle is a function of a first side, a second side, and a third side of said micro prism, and wherein said micro prism deflects light with a chief ray angle entering said micro prism to an exit light which is parallel to a line normal to said third side of said micro prism; forming an intermediate layer on said micro prism by a second integrated optical process; and forming a micro lens on said intermediate layer by a third integrated optical process.
