Patent ID: 7955907

Claim:
A method for manufacturing a semiconductor device, comprising the steps of: forming a first film pattern by discharging a conductive material with a droplet discharge method; forming a first photosensitive material over the first film pattern; forming a first mask pattern by irradiating a region where the first film pattern and the first photosensitive material are overlapped with a laser beam and by developing; forming a source electrode and a drain electrode having a desired shape by etching the first film pattern using the first mask pattern as a mask; forming a semiconductor film over the source electrode and the drain electrode; forming a second photosensitive material over the semiconductor film; forming a second mask pattern by irradiating the second photosensitive material with a laser beam and by developing; forming a semiconductor region having a desired shape by etching the semiconductor film using the second mask pattern as a mask; and forming an insulating film and a gate electrode over the semiconductor region.
