Abstract:
A method for fabricating a semiconductor device is provided. A first gate pattern and a second gate pattern are adjacent to each other and are formed on an active region of a substrate. The active region is defined by an isolation film. A first recess is formed between the first gate pattern and the second gate pattern. A first sacrificial film pattern is formed on a bottom surface of the first recess using a directional deposition process. A second recess is formed by etching the first recess using the first sacrificial film pattern as a etch mask. The first recess is laterally extended to form the second recess.
