Patent ID: 8253142

Claim:
A solid-state imaging device comprising: (a) a sensor including a p-type storage region disposed on an n-type impurity region; and (b) a passivation section disposed above the sensor and effective to transmit at least ultraviolet light to the sensor, the passivation section having only (1) a single-layer on-chip convex lens comprised of a first SiN film and formed by plasma-enhanced chemical vapor deposition, and (2) a planarizing film comprised of a second SiN film and formed by plasma-enhanced chemical vapor deposition and which is disposed directly below the lens and between the lens and the sensor; (c) a first insulating film composed of SiO 2 and disposed between the planarizing film and a transfer electrode, the first insulating film being common to the transfer electrode and an adjacent transfer electrode; (d) a second insulating film disposed between the first insulating film and the transfer electrode, the second insulating film being common to the transfer electrode and the adjacent transfer electrode; and (e) a shading film disposed between the first insulating film and the second insulating film, the shading film extending over a portion of the sensor such that an aperture is created over a portion of the sensor, wherein, the planarizing film is in direct and contiguous contact with the on-chip lens and has a substantially planar top surface and a bottom surface corresponding to a shape of an underlying transfer electrode, the first SiN film has a planar bottom surface that is in contact with and conforms to the substantially planar top surface of the second SiN film in at least a region that overlaps the aperture.
