Title: Semiconductor device and manufacture thereof
Inventor: MIZUNO BUNJI
IPC: H01L29/78
Filed: 1991-12-02
Abstract: PURPOSE:To get a semiconductor device where a body contact can be provided in a channel region without marring the performance of a MOSFET by arranging an ion nonimplantation area for formation of a buried insulating layer under the channel region. CONSTITUTION:A CVD SiO2 layer is formed on the surface 2A of a silicon single crystal substrate 2, and is etched to form an implantation mask 4 in the shape surrounding an region where ions are implanted. When ions are implanted from the surface 2A of the substrate with a nitrogen ion beam 5, a buried nitride film 7 is made, inside the substrate 2, at the section where the implantation mask 4 does not exist. A surface silicon layer 9 remains thereon, and an edge gutter part 10 is formed by cubical expansion, and high- concentration ion implantation into source and drain regions is prevented in a self alignment manner by providing the projection 19 of the silicon active area 26 isolated with a LOCOS area 12 below a polysilicon gate electrode 18 without a buried nitride film. Accordingly, a body contact part can be provided without wiring through the projection 19 without marring the performance of the MOSFET.
