Abstract:
1. A method for forming a semiconductor device comprising: forming a first semiconductor island comprising silicon over a substrate; forming a second semiconductor island comprising silicon over said substrate; forming a first source region, a first drain region and a first channel region for a pixel thin film transistor in said first semiconductor island; forming a second source region, a second drain region and a second channel region for a driver circuit thin film transistor in said second semiconductor island, said driver circuit thin film transistor provided in a driver circuit; forming a first interlayer insulating film over said first semiconductor island and said second semiconductor island; forming a first source electrode and a first drain electrode and a second source electrode and a second drain electrode over said first interlayer insulating film; forming a second interlayer insulating film over said first source electrode and said first drain electrode and said second source electrode and said second drain electrode; forming a conducting reflective film over said second interlayer insulating film; and patterning said conducting reflective film into a reflective pixel electrode and a conducting line simultaneously, said pixel electrode connected with one of said first source region and said first drain region for said pixel thin film transistor through one of said first source electrode and said first drain electrode, said conducting line connected with the other of said first source region and said first drain region through the other of said first source electrode and said first drain electrode and connected with one of said second source region and said second drain region through one of said second source electrode and said second drain electrode.
