    摘要: The invention provides a method of small geometry gate formation on the surface of a high-K gate dielectric. The method provides for processing steps that include gate pattern trimming, gate stack etch, and removal of exposed regions of the high-K dielectric to be performed efficiently in a single etch chamber. As such, process complexity and processing costs are reduced while throughput and overall process efficiency is improved. The method includes fabricating a high-K gate dielectric etch stop dielectric layer on the surface of a silicon substrate to protect the silicon substrate from erosion during an etch step and to prove a gate dielectric. A polysilicon layer is fabricated above the high-K dielectric layer. An anti-reflective coating layer above the polysilicon layer, and a mask is fabricated above the anti-reflective coating layer to define a gate region and an erosion region. The sequence of etching steps discussed above are performed in-situ in an enclosed high density plasma etching chamber environment.

    摘要: A thin filmed fully-depleted silicon-on-insulator (SOI) metal oxide semiconductor field defect transistor (MOSFET) utilizes a local insulation structure. The local insulative structure includes a buried silicon dioxide region under the channel region. The MOSFET body thickness is very small and yet silicon available outside of the channel region and buried silicon dioxide region is available for sufficient depths of silicide in the source and drain regions. The buried silicon dioxide region can be formed by a trench isolation technique or a LOCOS technique.
