Abstract:
A method of fabricating a semiconductor device, comprising the steps of:applying resist on a semiconductor substrate; patterning said resist thereby forming a protective pattern made of said resist in a shape covering a predetermined area on said semiconductor substrate and exposing an air bridge connecting portion at an end thereof; forming a conductive film covering said protective pattern, said conductive film being directly connected to said air bridge connecting portion; forming an insulating film covering said conductive film while said protective pattern is covered with said conductive film; processing said insulating film and said conductive film to form air bridge wiring connected with said air bridge connecting portion following a shape of said protective pattern and to form an air bridge protective film covering said air bridge wiring, said air bridge wiring being made of said conductive film; and removing said protective pattern to form a hollow between said air bridge wiring and said predetermined area.
