Patent ID: 8729650

Claim:
A solid-state imaging device comprising: a sensor including a p-type storage region disposed on an n-type impurity region; and a section disposed above the sensor and including (a) a single-layer on-chip convex lens, (b) a planarizing film disposed below the single-layer on-chip convex lens, and (c) an insulating film disposed below the planarizing film, wherein, the planarizing film is in direct and contiguous contact with the single-layer on-chip convex lens and has a substantially planar top surface and a bottom surface having corrugations corresponding to a shape of an underlying transfer electrode, and all the single-layer on-chip convex lens, the planarizing film, and the insulating film are made from an inorganic material which transmits at least ultraviolet light to the sensor, wherein the single-layer on-chip convex lens, the planarizing film, the insulating film, and the sensor are arranged such that the ultraviolet light passes through the single-layer on-chip convex lens, then through the planarizing film, and then through the insulating film to the sensor.
