Patent ID: 7211961

Claim:
A method for forming a circuit comprising: forming a first semiconductor layer and a second semiconductor layer, said first semiconductor layer provided over a substrate and comprising a first part to become a first channel region provided between a first source region and a first drain region, said second semiconductor layer provided over said substrate and comprising a second part to become a second channel region provided between a second source region and a second drain region wherein said first semiconductor layer and said second semiconductor layer are crystallized by laser irradiation; forming a first gate electrode adjacent to said first part to become said first channel region, with a first gate insulating film therebetween; and forming a second gate electrode adjacent to said second part to become said second channel region, with a second gate insulating film therebetween, wherein said first channel region and said second channel region are arranged to be point-symmetric, wherein said first gate electrode is connected with said second gate electrode through a conductive part, wherein a first source electrode connected with said first source region is connected with a second source electrode connected with said second source region, wherein a first drain electrode connected with said first drain region is connected with a second drain electrode connected with said second drain region, and wherein said conductive part bends at a location of said conductive part from said first channel region to said second channel region.
