Patent ID: 7038241

Claim:
A channel-etch thin film transistor comprising: a gate electrode over a substrate; a gate insulation film extending over said gate electrode and said substrate; an active layer including a channel region over said gate insulation film; a source region and a drain region on said active layer; a source electrode connected with said source region, and said source electrode including a source electrode primary portion in contact with said source region and a source electrode lead portion extending from said source electrode primary portion; and a drain electrode connected with said drain region, and said drain electrode including a drain electrode primary portion in contact with said drain region and a drain electrode lead portion extending from said drain electrode primary portion, wherein at least one of said source electrode and said drain electrode is separated from a side wall of said active layer by an inter-layer insulator, said at least one of said source electrode and said drain electrode including a first lead part extending over said inter-layer insulator and a second lead part extending under said inter-layer insulator and over said gate insulation film, wherein said second lead part is in contact with said gate insulation film.
