Title: Method for fabricating metal oxide semiconductor
Inventor: IN SOOL CHUNG
IPC: H01L21/335
Filed: 1996-03-07
Granted: 1996-12-01
Abstract: A method for fabricating a metal oxide semiconductor field effect transistor in which source/drain junctions are formed by depositing and etching an oxide film having a desired thickness prior to the formation of a pocket region carried out by a pocket ion implantation after forming a gate oxide film and gate electrode on a channel region formed by implanting impurity ions in a silicon substrate. The pocket region is formed by impurity ions in source/drain regions exposed by etching the oxide film. Accordingly, it is possible to reduce the thermal budget applied to the source/drain junctions. As a result, the lateral diffusion of the impurity ions implanted in the source/drain junctions can be suppressed as much as possible. That is, the transistor fabricated in accordance with the present invention has a channel length longer than that obtained in accordance with the prior art. Accordingly, the transistor can have a highly compact or densely integrated size. Since source/drain eletrodes are separately formed from each other in accordance with the present invention, the insulation between the source/drain electrodes can be effectively obtained.
