摘要:
The present invention provides a semiconductor device comprising: a semiconductor layer (3); a gate electrode (11) formed on the semiconductor layer (3) via a gate insulation film (10); and a first insulation film (13) formed at one or more of sidewalls of the semiconductor layer (3), the gate insulation film (10) and the gate electrode (11); wherein the first insulation film (13) overlies a part of the gate insulation film (10) surface. According to the semiconductor device, leakage current at the isolation edge can be suppressed and thus reliability can be improved.
