Abstract
A semiconductor device is provided as follows. A tunnel insulation layer is disposed on a substrate. The tunnel insulation layer includes a first silicon oxide layer, a second silicon oxide layer, and a silicon layer interposed between the first silicon oxide layer and the second silicon oxide layer. The silicon layer has a thickness smaller than a thickness of each of the first silicon oxide layer and the second silicon oxide layer. A gate pattern is disposed on the tunnel insulation layer.
