Title: Semiconductor device and its manufacturing method
Inventor: MATSUSHIRO TOMOKO
IPC: H01L29/739
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To solve the problem of the difficulty in forming an element that has required turn-off time and on characteristics, and inhibiting polishing errors by a thin-layer substrate. SOLUTION: In IGBTs, an n buffer layer 23 is formed under an n<-> high resistance layer 21, where MOS gate structure is formed, and an n<+> buffer layer 31 is formed between the n buffer layer 23 and a p<+> drain layer. The p<+> drain layer has a small dose, thus reducing injection efficiency in carriers, increasing speed, without controlling life time, and hence reducing the on voltage. The n buffer layer 23 can prevent vibration from being generated in current and voltage, without abruptly stopping the growth of a depletion layer in turn- off. The n<+> buffer layer 31 sufficiently secures pressure resistance, when reverse bias is applied.
