摘要: A semiconductor device having a double spacer and a method of manufacturing the device are provided. The semiconductor device includes a first spacer formed on the sidewall of a gate electrode and a second spacer formed on the slanted sidewall of the first spacer. A first impurity region is formed doped with a first conductivity type impurity at a first concentration and formed at a small junction depth in the substrate to self-align at the edge of the gate electrode. A second impurity region doped with second conductivity type impurity at a second concentration is formed at a large junction depth in the substrate to self-align at the edge of the first spacer. A third impurity region doped with the first conductivity type impurity at a third concentration is formed at a medium junction depth in the second impurity region to self-align at the edge of the second spacer.
