Abstract:
1. A transistor, comprising: a polycrystalline silicon semiconductor layer on a substrate, the semiconductor layer having a source region and a channel-and-drain region, the channel-and-drain region having a channel region and a drain region; a first insulation film on the semiconductor layer; a gate electrode on the first insulation film on the channel region of the semiconductor layer; a second insulation film on the gate electrode; a source electrode and a drain electrode on the second insulation film to project through the first insulation film and the second insulation film so that the source electrode and the drain electrode are coupled to the source region and the drain region respectively, the drain electrode covering at least part of the channel region; and a contact hole in the second insulation film above the channel region, the contact hole coupling the drain electrode and the gate electrode, wherein such coupling with the gate electrode is over the channel region.
