Abstract: According to embodiments of the inventive concept, a gate electrode is formed on a substrate, and a first spacer, a second spacer, and a third spacer are sequentially formed on a sidewall of the gate electrode. The substrate is etched to form a recess region. A compressive stress pattern is formed in the recess region. A protective spacer is formed on a sidewall of the third spacer. When the recess region is formed, a lower portion of the second spacer is removed to form a gap region between the first and third spacers. The protective spacer fills the gap region.
