Abstract

A method of fabricating an image sensor includes the following steps. A semiconductor substrate is provided. A first photoresist structure is formed on the semiconductor substrate. A second photoresist structure is formed on the semiconductor substrate and covering the first photoresist structure. A third photoresist structure is formed on the semiconductor substrate and covering the first photoresist structure and the second photoresist structure. A first etching back process is performed to remove a first portion of the third photoresist structure above a top surface of the second photoresist structure. A second etching back process is performed to remove a portion of the second photoresist structure above a top surface of the first photoresist structure and to remove a second portion of the third photoresist structure above the top surface of the first photoresist structure.
