SEMICONDUCTOR DEVICE AND METHOD FOR DRIVING THE SAME

摘要

PURPOSE: A semiconductor device and a driving method thereof are provided to alleviate the concentration of an electric field by making the distance between an electric field control electrode and a semiconductor layer longer than the distance between a gate electrode and the semiconductor layer. CONSTITUTION: A source electrode(102a) and a drain electrode(102b) are formed on a substrate(100). A semiconductor layer(104) is formed between the source electrode and the drain electrode. A first insulation layer(106) is formed on the semiconductor layer. A gate electrode(108) is formed on the first insulation layer. A second insulation layer(110) is formed on the gate electrode. An electric field control electrode(112) is formed on the second insulation layer.
