Abstract:
A method of coating a semiconductor wafer with resin comprising the steps of:placing a semiconductor wafer with a bump in a prescribed position on a bottom surface of a cavity formed in a molding surface of one of opposed molds for resin coating with a surface of said semiconductor wafer having said bump facing upward; supplying a required amount of a resin material in said cavity; applying a film for exposing said bump onto a molding surface of the other of said molds; closing said molds together; heating to melt said resin material in said cavity; pressing said film against said bottom surface of said cavity by a pressing member provided on said molding surface of said other mold; abutting said film against a leading edge of said bump in said cavity in said pressing step; and coating said surface having said bump of said semiconductor wafer with said resin by applying a pressure to said resin on said cavity through said film in said pressing step.
