Abstract: The present disclosure relates to an SRAM memory cell. The SRAM memory cell has a semiconductor substrate with an active area and a gate region positioned above the active area. A butted contact extends along a length (i.e., the larger dimension of the butted contact) from a position above the active area to a position above the gate region. The butted contact contains a plurality of distinct regions having different widths (i.e., the smaller dimensions of the butted contact), such that a region spanning the active area and gate region has width less than the regions in contact with the active area or gate region. By making the width of the region spanning the active area and gate region smaller than the regions in contact with the active area or gate, the etch rate is reduced at a junction of the gate region with the active area, thereby preventing etch back of the gate material and leakage current.

Abstract: Improvements are achieved in the characteristics of a semiconductor device including SRAM memory cells. Under an active region in which an access transistor forming an SRAM is disposed, a p-type semiconductor region is disposed via an insulating layer such that the bottom portion and side portions thereof come in contact with an n-type semiconductor region. Thus, the p-type semiconductor region is pn-isolated from the n-type semiconductor region, and the gate electrode of the access transistor is coupled to the p-type semiconductor region. The coupling is achieved by a shared plug which is an indiscrete conductive film extending from over the gate electrode of the access transistor to over the p-type semiconductor region. As a result, when the access transistor is in an ON state, a potential in the p-type semiconductor region serving as a back gate simultaneously increases to allow an increase in an ON current for the transistor.
