PROBLEM TO BE SOLVED: To provide a method of manufacturing a thin film semiconductor device, which is capable of easily and surely forming a semiconductor thin film whose plane orientation is well controlled. SOLUTION: The method of manufacturing the thin film semiconductor device comprises a micropore forming process (S103) of forming micropores in a board whose one side is at least insulating, a crystallization promoting film deposition process (S104) of depositing a crystallization promoting film that promotes the crystallization of a semiconductor film on the board including the bottoms of the micropores, a removing process (S105) of removing the crystallization promoting film from the surface of the board, a semiconductor film deposition process (S106) of depositing an amorphous semiconductor film, and a melting/crystallizing process (S108) of forming a nearly single crystal semiconductor crystal grain having a prescribed plane orientation in a region where the micropore is located at its center by melting/crystallizing the amorphous semiconductor film.
