Camera device and method of manufacturing the same

摘要

A camera device having favorable multiplication characteristics (quantum efficiency) as well as improved sensitivity in a visible light region (especially the region on the red side) and a method of manufacturing the same are provided. The camera device includes a hole injection stop layer, a first photoelectric converting layer including selenium, a second photoelectric converting layer having spectral sensitivity characteristics which are different from those of the first photoelectric converting layer, a third photoelectric converting layer including selenium, and an electron injection stop layer. As a result, it is possible to improve multiplication characteristics (quantum efficiency) and to improve the sensitivity in the visible light region (especially the region on the red side) simultaneously.
