Patent ID: 6913985

Claim:
A method of manufacturing a semiconductor device wherein semiconductor thin film pieces are formed on a first substrate, and then transferred to a second substrate, comprising the steps of: forming a peeling layer on said first substrate; forming a semiconductor thin film which will become said semiconductor thin film pieces, on said peeling layer; forming a support material film on said semiconductor thin film; forming individual support materials by patterning said support material film; forming grooves extending through said semiconductor thin film to said peeling layer by patterning said semiconductor thin film using said individual support materials as a mask, dividing said semiconductor thin film into said plurality of semiconductor thin film pieces by the grooves, and forming a plurality of assemblies each comprising one of said semiconductor thin film pieces and one of said individual support materials fixed thereto; and separating said semiconductor thin film pieces from said first substrate in a state wherein said individual support materials have been fixed to said semiconductor thin film pieces, and affixing said semiconductor thin film pieces to said second substrate.
