One embodiment of inventive concepts exemplarily described herein may be generally characterized as a semiconductor device including an isolation region within a substrate. The isolation region may define an active region. The active region may include an edge portion that is adjacent to an interface of the isolation region and the active region and a center region that is surrounded by the edge portion. The semiconductor device may further include a gate electrode on the active region and the isolation region. The gate electrode may include a center gate portion overlapping a center portion of the active region, an edge gate portion overlapping the edge portion of the active region, and a first impurity region of a first conductivity type within the center gate portion and outside the edge portion. The semiconductor device may further include a gate insulating layer disposed between the active region and the gate electrode. |
