Abstract:
A field effect transistor structure that uses thin semiconductor on insulator channel to control the electrostatic integrity of the device. Embedded stressors are epitaxially grown in the source/drain area from a template in the silicon substrate through an opening made in the buried oxide in the source/drain region. In addition, a dielectric layer is formed between the embedded stressor and the semiconductor region under the buried oxide layer, which is located directly beneath the channel to suppress junction capacitance and leakage.
