Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of short circuits between wires due to micro-scratches on the surface of an interlayer insulating film flattened by chemical mechanical pushing(CMP) by forming an insulating film so as to flatten the surface of the interlayer insulating film by burying the micro-scratches. SOLUTION: An interlayer insulating film 4 is formed on a semiconductor substrate 1 on which a field oxide film 2 and the gates 3, etc., of transistors are formed. Then a flat interlayer insulating film 4-1 is formed by polishing the insulating film 4 by CMP. Since micro-scratches 5 are formed on the surface of the insulating film 4-1 when the surface of the film 4-1 is polished by CMP, the micro-scratches are flattened by filling up the scratches 5 by forming an insulating film 7 composed of a plasma TFOS oxide film. Therefore, aluminum, etc., used for forming wiring 6 does not get in the micro-scratches 5 and the occurrence of short circuits between wires can be prevented when the wiring 6 is formed by dry etching, etc., after a pattern is formed of a photoresist.
