Abstract:
1. A manufacturing method of a thin-film structural body, comprising: (a) selectively forming a wiring on a first insulating film; (b) forming a second insulating film having a hole section for selectively exposing said wiring on said wiring and said first insulating film; (c) forming a sacrifice film on said second insulating film; (d) a first etching to form a recessed section with said sacrifice film remaining on said first insulating film side by using an anisotropic etching process; (e) a second etching to form an anchor hole for exposing said wiring by removing said sacrifice film remaining on said first insulating film side of said recessed section by using isotropic etching process; (f) forming a thin-film layer on said anchor hole and said sacrifice film by using a conductive material, and (g) removing said sacrifice film by etching.
