Abstract:
1. A method of manufacturing a transistor, the method comprising: forming a gate electrode over a substrate; applying an inorganic material over the gate electrode to form a first gate insulating layer; forming a second gate insulating layer on the first gate insulating layer, the second gate insulating layer including an organic polymer material, the first gate insulating layer having a higher dielectric constant than the second gate insulating layer; forming a source electrode and a drain electrode on the second gate insulating layer; irradiating the second gate insulating layer with a polarized light while heating the second gate insulating layer to make at least a portion of the organic polymer material to be oriented in a first direction, wherein the second gate insulating layer is heated at a temperature within a range of 100 to 200 degrees centigrade not including 200 degrees centigrade; forming a semiconductor layer on the second gate insulating layer such that the semiconductor film is in a direct contact with the second gate insulating layer and is caused to be aligned in the first direction.
