Abstract: Provided is a method of fabricating a semiconductor device. The method includes forming a gate pattern on a semiconductor substrate, injecting amorphization elements into the semiconductor substrate to form an amorphous portion at a side of the gate pattern, removing the amorphous portion to form a recess region, and forming a source/drain pattern in the recess region. When the recess region is formed, an etch rate of the amorphous portion is substantially the same in two different directions (e.g., and any other direction) of the semiconductor substrate.
