Patent JP-S6381846-A (JP)
Title: Manufacture of semiconductor device
Inventor: NISHIURA AKIRA
IPC: H01L29/78
Filed: 1986-09-25
Abstract: PURPOSE:To obtain a sufficiently large latching current with an ON resistance maintained low in a insulated gate type bipolar transistor by a method wherein a collector region (P-layer) is formed by diffusion, a gate electrode is subjected to over-etching, and then an n<+> layer is formed by diffusion. CONSTITUTION:On the surface of a gate electrode 6, a gate insulating film 5 and photoresist film 9 are formed, the latter for a pattern for the gate electrode 6. The gate electrode 6 and gate insulating film 5 are partially removed in a photoetching process for the formation of a pattern 10. A(p) layer 3 is formed by diffusion with the pattern 10 serving as a mask. The photoresist film 9 serves as a mask again for the etching of the periphery 11 of the gate electrode 6 and of the gate insulating film 5. Next, on the surface of the (p) layer 3, a photoresist film 12 is formed, a pattern 13 is built for the selective formation of an n<+> layer 4, and then the photoresist film 9 is removed. The pattern 13 serves as a mask in a process of forming the n<+> layer 4 by diffusion. In this design, the third region (collector region) is formed deeper than in an ordinary power MOSFET. Latching is less prone to occur because resistance is reduced in the collector region and an ON resistance may be maintained low because the channel length does not grow large.
