IPC: H01L29/06
Filed: 2001-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent a faulty gate withstand voltage without increasing standardized ON resistance. SOLUTION: A source region is formed by an n<+> -type substrate, a trench 2 is formed on a principal surface of the n<+> -type substrate, and then a p-type base region 3, an n<-> -type drift region 4, and an n<+> -type drain region 5 are sequentially epitaxially grown in the trench 2. Then, after the trench 6 is formed, a gate oxide film 7 and a gate electrode 8 are formed on the inside wall of the trench 6. In this manner, making a point where the surfaces of the epitaxially grown films contact each other an n<+> -type drain region 5 eliminates the need for arranging the gate electrode 8 so as to avoid the point to thereby prevent the standardized ON resistance from increasing. This can prevent a faulty gate withstand voltage without increasing the standardized ON resistance.
