ABSTRACT:
Transistor architectures and fabrication processes generate channel strain without adversely impacting the efficiency of the transistor fabrication process while preserving the material quality and enhancing the performance of the resulting transistor. Transistor strain is generated is PMOS devices using a highly compressive post-salicide boron doped carbon capping layer applied as a blanket over on at least the source and drain regions. The stress from this capping layer is uniaxially transferred to the PMOS channel through the source-drain regions to create compressive strain in PMOS channel.
