IMAGE SENSOR AND FABRICATING METHOD THEREOF

摘要

PURPOSE: An image sensor and a fabricating method thereof are provided to stably maintain the potential of first wells by allowing a first well bias, applied to one of the first wells, to be shared with other first wells. CONSTITUTION: In an image sensor and a fabricating method thereof, a substrate(110) defines a pixel region(I) and a non-pixel region(II). . A first well(112) is formed within the substrate corresponding to the non-pixel region. A wiring structure(122) comprises a plurality of wires(124a-124c) and a plurality of an insulating layer(122). The first well and the bias well are the same conductive type.
