    摘要: A method is provided for fabricating a semiconductor device. According to the method, a semiconductor layer is formed over a semiconductor-on-insulator substrate, and a gate is formed on the semiconductor layer. Source and drain extension regions and a deep drain region are formed in the semiconductor layer. A deep source region is formed in the semiconductor layer. A drain metal-semiconductor alloy contact is located on the upper portion of the deep drain region and abutting the drain extension region. A source metal-semiconductor alloy contact abuts the source extension region. The deep source region is located below and contacts a first portion of the source metal-semiconductor alloy contact. The deep source region is not located below and does not contact a second portion of the source metal-semiconductor alloy contact. The second portion of the source metal-semiconductor alloy contact is an internal body contact that directly contacts the semiconductor layer.
