IPC: H01L29/78
Filed: 2000-11-21
Abstract: PROBLEM TO BE SOLVED: To increase a latch-up resistance and to reduce a leakage current at a reverse voltage applying time by improving a trade-off relation between an on voltage and turn-off loss of a MOS semiconductor device such as an IGBT or the like. SOLUTION: A method for manufacturing the semiconductor device comprises the steps of forming a gate electrode 3 on a semiconductor substrate 1 via an insulating film 2, and forming a p-type base region 6 and an n+ type emitter region 7 on a thin film semiconductor layer 11 formed on the electrode 3 via an insulating film 5 through a coupled semiconductor 12 from the surface of the substrate 1. An emitter layer is thinned for microminiaturization of an emitter structure, and a latch-up resistance is increased by remotely separating a hole current in the p-type region 6 from the region 7. Simultaneously, an impurity concentration of the region 6 is lowered, a leakage current at a reverse voltage applying time is reduced, and hence an operation as a bidirectional device can be performed.
