摘要
PURPOSE: A method for manufacturing an image sensor is provided to minimize leakage by wet-etching a trench for isolating pixel regions.;CONSTITUTION: A substrate(100) includes a pixel region and a peripheral region. A photosensitive pattern exposing a photodiode is formed on the substrate of the pixel region. A second conductive ion implantation region(110) is formed on the exposed photo diode region. The photosensitive pattern is removed. A trench for isolating pixels is formed by wet-etching the substrate of the pixel region. A pixel isolation layer(120) is formed in the trench. A first conductive ion implantation region(130) is formed on the photodiode region.;COPYRIGHT KIPO 2010
