Title: Solid-state image pickup element and its manufacturing method
Inventor: MORI HIROYUKI
IPC: H04N5/335
Filed: 2001-08-03
Abstract: PROBLEM TO BE SOLVED: To shorten the distance from an optical sensor to an on-chip lens. SOLUTION: On the surface of wiring 126 and the surface of an interlayer insulating film 124 in the side section of the wiring 126, a buffer layer 4 composed of an insulating material having a higher polish selection rate than an interlayer insulating film 130 has is formed. The surface height of the insulating film 130 conforms to that of the buffer layer 4 formed on the wiring 126 and a passivation film 132 is formed on the insulating film 130. The insulating film 130 can be formed by flattening the surface of its material by polishing after the material is deposited. At the time of polishing the material, the polishing can be stopped on the surface of the buffer layer 4, because the material of the buffer layer 4 has a higher polish selection rate than that of the insulating film 130 has.  Consequently, only the thin buffer layer 4 can be interposed between the wiring 126 and passivation film 132 and, in addition, it becomes unnecessary to form a flattened film on the passivation film 132.
