Title: Semiconductor device
Inventor: MORI MUTSUHIRO
IPC: H01L21/336
Filed: 1987-04-06
Abstract: PURPOSE:To realize the large current operation of an device, by a method wherein a polycrystal semiconductor is arranged on the side-wall of a gate electrode via an insulator, impurity is diffused from the polycrystal semiconductor to a p-layer to form an n<+> layer, and both or either one of an n<+> type polycrystal semiconductor and the n<+> layer is short-circuited to the p-layer by a source electrode. CONSTITUTION:An n<-> layer 12 and a p-layer 13 are formed on a semiconductor layer 11, and an n<+> type polycrystalline semiconductor 32, for example, is formed on the side-wall of a gate electrode 31 via an insulator 22. On the p-layer 13 side of the semiconductor 32, a semi-circular n<+> layer 14 is formed by self-alignment, so as to surround the polycrystalline semiconductor 32. A source electrode 42 is in low resistance-contact with the n<+> type polycrystalline semiconductor 32 on the side-wall, the n<+> layer 14 and the p-layer 13. As the n<+> layer 14 is formed by self-alignment with the thin polycrystalline substrate 32 on the side-wall, the width of the n<+> layer 14 is made small. Further, as the n<+> layer 14 and the p-layer 13 are short-circuited to the polycrystalline semiconductor 32 by the source electrode 42, the rate occupied by a gate region can be increased, so that the large current operation of a semiconductor device is enabled.
