Abstract:
1. A method of manufacturing a solid state imaging device, comprising 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; forming a microlens in the microlens material layer corresponding to the light receiving portion; forming a fluorine-containing siloxane film on the microlens material layer, thereby reducing reflection; etching the microlens material layer and the fluorine-containing siloxane film over the pad portion to form an opening; and imparting hydrophilicity to a surface of the fluorine-containing siloxane film and an inside portion of the opening by an oxygen radical treatment performed in a temperature range from 25 C to 35 C.
