US 2009/0212383 A1 · SOLID-STATE IMAGING DEVICE, CAMERA MODULE AND ELECTRONIC EQUIPMENT MODULE

Abstract

To provide a back-illuminated type solid-state imaging device capable of color separation of pixels without using a color filter, and a camera module and an electronic equipment module which incorporate the solid-state imaging device. A solid-state imaging device including: a photoelectric conversion element PD formed in a semiconductor substrate 22; a reading-out part which reads out signal charges from the photoelectric conversion element PD formed on one surface side of the semiconductor substrate 22; the other surface of the semiconductor substrate 22 made to a light incidence surface; and a pixel which exclusively makes light of a specific wavelength or longer photoelectrically converted, by adjusting pn junction depths h2 [h2 r, h2 g, h2 b] between the photoelectric conversion element PD and an accumulation layer 28 on the light incidence surface side. A camera module and an electronic equipment module which incorporate the solid-state imaging device.
