20080315340 | SOLID-STATE IMAGING DEVICE AND METHOD OF FABRICATING THE SAME - A solid-state imaging device includes a layer including an on-chip lens above a sensor section, and the layer including the on-chip lens is composed of an inorganic film which transmits ultraviolet light. The layer including the on-chip lens may further include a planarizing film located below the on-chip lens. A method of fabricating a solid-state imaging device includes the steps of forming a planarizing film composed of a first inorganic film, forming a second inorganic film on the planarizing film, forming a lens-shaped resist layer on the second inorganic film, and etching back the resist layer to form an on-chip lens composed of the second inorganic film. The first inorganic film constituting the planarizing film and the second inorganic film constituting the on-chip lens preferably transmit ultraviolet light. | 12-25-2008 |
