Abstract

See full text

An SRAM structure includes first and second gate strips extending along a first direction. A first active region extends across the first gate strip from a top view, and forms a first pull-up transistor with the first gate strip. A second active region extends across the second gate strip from the top view, and forms a second pull-up transistor with the second gate strip. From the top view the first active region has a first stepped sidewall facing away from the second active region. The first stepped sidewall has a first side surface farthest from the second active region, a second side surface set back from the first side surface along the first direction, and a third side surface set back from the second side surface along the first direction.
