IPC: H01L29/80
Filed: 2001-05-16
Abstract: PROBLEM TO BE SOLVED: To reduce on-state resistance in a silicon carbide semiconductor device provided with a planar-type J-FET. SOLUTION: In a surface region of an n<-> type epitaxial layer 2, a p<+> type region 4a is formed at a specified distance away from a first gate region 3. On the surface of a channel layer 5, a p<+> type epitaxial layer 4b is formed, and a p<+> type contact region 4c is so extended as to connect the p<+> type epitaxial layer 4b and the p<+> type region 4a. The p<+> type contact region 4a, the p<+> type epitaxial layer 4b, and the p<+> type contact region 4c constitute a second gate region 4.  Due to this structure, the channel layer 5 and a part of the n<-> type epitaxial layer 2 which is located between the first and second gate regions 3 and 4 serve for a channel, making the total distance L of the length of the channel layer 5 and that of the part of the n<-> type epitaxial layer 2 which is located between the first and second gate regions 3 and 4 nearly equal to a channel length of a conventional J-FET. Consequently, a J-FET resistance component can be eliminated, thus reducing the on-state resistance.
