摘要： Disclosed is a p-type field effect transistor (pFET) structure and method of forming the pFET. The pFET comprises embedded silicon germanium in the source/drain regions to increase longitudinal stress on the p-channel and, thereby, enhance transistor performance. Increased stress is achieved by increasing the depth of the source/drain regions and, thereby, the volume of the embedded silicon germanium. The greater depth (e.g., up to 100 nm) of the stressed silicon germanium source/drain regions is achieved by using a double BOX SOI wafer. Trenches are etched through a first silicon layer and first buried oxide layer and then the stressed silicon germanium is epitaxially grown from a second silicon layer. A second buried oxide layer isolates the pFET.

摘要： A semiconductor structure and a method for fabricating the semiconductor structure include a semiconductor substrate having a cross-section hourglass shaped channel region. A stress imparting layer is located adjacent the channel region. The hourglass shape may provide for enhanced vertical tensile stress within the channel region when it is longitudinally compressive stressed by the stress imparting layer.
