SOLID STATE IMAGING DEVICE AND METHOD OF MANUFACTURING THE SAME |
摘要 |
According to one embodiment, a pixel detecting light having the longest wavelength in a picture element includes a protective film which is disposed on a photodiode at a surface side facing a light incident surface of a semiconductor substrate and a first diffraction grating portion which is disposed on the protective film and where columnar holes penetrating in a thickness direction are two-dimensionally arrayed. Diameter and array period of the holes are selected so that the first diffraction grating portion reflects light transmitting through a filter disposed on the pixel. |
