SOLID-STATE IMAGING DEVICE AND FABRICATING METHOD THEREOF FOR REDUCING IMAGE NOISE AND IMPROVING RELIABILITY

摘要

PURPOSE: A solid-state imaging device and a fabricating method thereof are provided to reduce image noise and improve reliability by using lowα-ray glass as a light-transmission member. CONSTITUTION: A semiconductor substrate(101) has a first surface. A solid-state imaging device(102) in the first surface of the semiconductor substrate and includes a light-receiving region. A light-transmission member(201) has a second surface and a third surface. The second surface is opposite to the third surface. The light-transmission member and the first surface of the semiconductor substrate are used for defining a gap between the second surface of the light-transmission member and an outer surface of the light-receiving region. An external connection terminal(BP) is connected to the solid-state imaging device. The light-transmission member includes lowα-ray glass.
