发明名称 BODY CONTACT STRUCTURE FOR A SEMICONDUCTOR DEVICE
摘要 Embodiments of the invention provide SOI body-contacted transistors that can be used for high frequency analog and digital circuits. In accordance with certain embodiments of the invention, the SOI transistor gate can have an“I”shape, similar to the shape of the gate of a floating body SOI transistor. However, a body region is provided that extends perpendicular to the width direction of the gate and is contacted at an end of the extended body region. To form such a body contact structure, a source/drain implant block mask and silicide block mask are used during the formation of the source/drain regions. The source/drain implant block mask and silicide block mask can be formed on the same region, but the silicide block mask can allow for the body contact portion at the end of the extended body region to be silicided during the siliciding of the source/drain regions.
