Abstract:
A method of manufacturing a semiconductor device including at least a p-channel thin film transistor, said method comprising:forming a semiconductor film on an insulating surface; forming a gate electrode over the semiconductor film with a gate insulating film interposed therebetween; introducing an n-type impurity into the semiconductor film at a first concentration using a first mask; introducing a p-type impurity into the semiconductor film at a second concentration higher than the first concentration using a second mask to form a channel forming region, at least a high concentration impurity region in contact with the channel forming region and at least a low concentration impurity region in contact with the high concentration impurity region; wherein the high concentration impurity region is located between the channel forming region and the low concentration impurity region; forming an insulating film over the semiconductor film, the gate electrode and the gate insulating film, said insulating film comprising a resin film.
