  • Method of manufacturing solid state imaging device, and solid state imaging device
    Patent number: 8884392
    Abstract: Disclosed herein is a method of manufacturing a solid state imaging device, including the steps of: forming a light receiving portion in a light receiving area of a semiconductor substrate; forming a pad portion in a pad area of the semiconductor substrate; forming a microlens material layer over the light receiving portion and the pad portion; providing the microlens material layer with a microlens corresponding to the light receiving portion; forming a low-reflection material layer on the microlens material layer; etching the microlens material layer and the low-reflection material layer over the pad portion to form an opening; and imparting hydrophilicity to a surface of the low-reflection material layer and an inside portion of the opening by a normal temperature oxygen radical treatment.
