| 摘要 |
A semiconductor device and a method of manufacturing a semiconductor device, the method including forming a gate insulation layer and a gate electrode on a substrate, forming a silicon nitride layer on the gate electrode and the gate insulation layer, partially implanting ions into the silicon nitride layer to convert an upper portion of the silicon nitride layer into a treated silicon layer including the ions, etching the treated silicon layer to form a spacer on a sidewall of the gate electrode, and forming an impurity region in the substrate adjacent to the gate electrode.
