Abstract:
A method of forming a semiconductor device includes, but is not limited to, the following processes. A first interlayer insulating film is formed. A hole is formed in the first interlayer insulating film. A second interlayer insulating film is formed, which buries the hole and covers the first interlayer insulating film. An interconnect groove is formed by selectively etching the second interlayer insulating film to leave the second interlayer insulating film in the hole. The second interlayer insulating film in the hole is removed.
