  • Patent number: 7060549
    Abstract: SRAM devices utilizing tensile-stressed strain films and methods for fabricating such SRAM devices are provided. An SRAM device, in one embodiment, comprises an NFET and a PFET that are electrically coupled and physically isolated. The PFET has a gate region, a source region, and a drain region. A tensile-strained stress film is disposed on the gate region and at least a portion of the source region and the drain region of the PFET. A method for fabricating a cell of an SRAM device comprises fabricating an NFET and a PFET overlying a substrate. The PFET and the NFET are electically coupled and are physically isolated. A tensile-strained stress film is deposited on the gate region and at least a portion of the source region and the drain region of the PFET.
