摘要： In a method of manufacturing a non-volatile memory device, a conductive structure is formed on a substrate. The conductive structure includes a tunnel oxide pattern, a first conductive pattern, a pad oxide pattern and a hard mask pattern. A trench is formed on the substrate using the conductive structure as an etching mask. An inner oxide layer is formed on an inner wall of the trench and sidewalls of the tunnel oxide pattern and the first conductive pattern. The inner oxide layer is cured, thereby forming a silicon nitride layer on the inner oxide layer. A device isolation pattern is formed in the trench, and the hard mask pattern and the pad oxide pattern are removed from the substrate. A dielectric layer and a second conductive pattern are formed on the substrate. Accordingly, the silicon nitride layer prevents hydrogen (H) atoms from leaking into the device isolation pattern.

摘要： A semiconductor device having a field effect transistor and a method of fabricating the same. In-situ doped epitaxial patterns are respectively formed at both sidewalls of a protruded channel pattern from a substrate by performing an in-situ doped epitaxial growth process. The in-situ doped epitaxial pattern has a conformal impurity concentration throughout. Accordingly, source/drain regions with a conformal impurity concentration are connected throughout a channel width of a channel region including both sidewalls of a protruded channel pattern. As a result, it is possible to maximize a driving current of the filed effect transistor, and an on-off characteristic can be highly stabilized.
