Cell structure of semiconductor device having an active region with a concave portion |
摘要 |
A cell structure of a semiconductor device includes an active region, having a concave portion, and an inactive region that defines the active region. A gate pattern in the active region is arranged perpendicular to the active region. A landing pad on the active region and the inactive region contacts the active region. A bit line pattern on the inactive region intersects the gate pattern perpendicularly, the bit line pattern being electrically connected to the landing pad and having a first protrusion corresponding to the concave portion of the active region.
