Abstract

An integrated circuit transistor includes an active region in a substrate, elongated along a first direction. A gate pattern is disposed on the substrate and crosses the active region along a second direction transverse to the first direction. The gate pattern includes an access gate portion disposed on the active region and narrowed at a central portion thereof. The gate pattern may further include a pass gate portion adjoining the access gate portion at the point beyond the edge of the active region, the pass gate portion having a lesser extent along the first direction than the access gate portion.
