Inventor: MOHAMETSUDO ANJIYUUMU
IPC: H01L29/78
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor structure using large tilt angle boron injection for reducing short channel effect and a sub-threshold current on substrate surface and in its vicinity by reducing the shifting or roll-offs of the threshold on the edge of channel. SOLUTION: A semiconductor structure is obtained by injecting boron at a non-vertical angle into the junction part between a channel 14 and a source/ drain 56 and the junction part between a field region 54 and the source/drain 56. By adding boron to a critical region, the threshold adjustment and implantation seeds, which are to be segregated and redistributed caused by the temperature cycle of a process, and a channel-stopping implantation seeds are replenished.
