摘要:
A transistor includes a substrate and a device isolation layer that is formed on the substrate to define an active region. A gate pattern crosses over the active region. A gate insulation layer is interposed between the gate pattern and the active region. Source and drain regions are formed in the active region adjacent to respective sides of the gate pattern. A channel region is disposed in the active region between the source and drain regions. The channel region includes a recessed portion.
