Abstract:
A pattern formation method comprising the steps of:forming an organic insulating film on a substrate; opening predetermined regions of said organic insulating film to form first openings and second openings in said organic insulating film, said first openings being formed for forming contact holes in said organic insulating film such that each of said second openings has a smaller opening area than that of each of said first openings and is opened to a depth located at least below a surface of said organic insulating film within a thickness of said organic insulating film; forming a resin film on said organic insulating film covering said first openings and said second openings; causing flow of said organic insulating film and said resin film to form a deformed organic insulating film resulting from said flow of said organic insulating film such that said first openings are changed to third openings each having smaller opening area than that of each of said first openings, and said second openings are covered by said deformed organic insulating film; and selectively removing only said resin film.
