Title: Method of manufacturing semiconductor device
Inventor: KASAI KOJI
IPC: H01L29/812
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device, having a desired size which is suited to high-temperature processings. SOLUTION: WSiN is formed into a film (step S12), and this film is etched (step S14) to form a dummy pattern.

In a step (S24) of selectively removing the dummy pattern, this pattern can be selectively removed, hardly changing the shape of a neighboring material SiO2, since the material of the dummy pattern has high selectivity to the neighboring material SiO2. As the result, a semiconductor device of a desired size can be manufactured.
