Abstract: In a metal-oxide semiconductor (MOS) transistor with an elevated source/drain structure and in a method of fabricating the MOS transistor with the elevated source/drain structure using a selective epitaxy growth (SEG) process, a source/drain extension junction is formed after an epi-layer is formed, thereby preventing degradation of the source/drain junction region. In addition, the source/drain extension junction is partially overlapped by a lower portion of the gate layer, since two gate spacers are formed and two elevated source/drain layers are formed in accordance with the SEG process. This mitigates the short channel effect and reduces sheet resistance in the source/drain layers and the gate layer.

Abstract: In a method of fabricating a non-volatile memory device with a silicon-oxide-nitride-oxide-silicon (SONOS) structure, a silicon nitride layer, which is a charge trapping layer, and a polysilicon layer, which is a control gate electrode, are electrically isolated from one another in the resulting structure. According to the method, a silicon oxide layer as a tunneling layer and a silicon nitride layer pattern as a charge trapping layer are formed on a semiconductor substrate; an oxidation process is performed to form a silicon nitride oxide layer, as a blocking layer, at top and sides of the silicon nitride layer pattern and to form a gate insulating layer at an exposed portion of the semiconductor substrate; and a control gate electrode is formed on the silicon nitride oxide layer and the gate insulating layer.
