Thin-film semiconductor device, lateral bipolar thin-film transistor, hybrid thin-film transistor, MOS thin-film transistor, and method of fabricating thin-film transistor

摘要

In a lateral bipolar transistor including an emitter, a base and a collector which are formed in a semiconductor thin film formed on an insulating substrate, the semiconductor thin film is a semiconductor thin film which is crystallized in a predetermined direction. In addition, in a MOS-bipolar hybrid transistor formed in a semiconductor thin film formed on an insulating substrate, the semiconductor thin film is a semiconductor thin film which is crystallized in a predetermined direction.
