    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: The invention provides a method of small geometry gate formation on the surface of a high-k gate dielectric wherein process complexity and processing costs are reduced while throughput and overall process efficiency is improved. The method may utilize photolithography illumination of 157 nm, 193 nm, 248 nm, or other suitable wavelengths to mask a gate region. An aggressive mask trim may be used to reduce the mask size such that it masks a narrow gate region. A hard mask is then fabricated over the narrow gate region and the gate and high-k dielectric are etched to expose the silicon substrate. The entire etch sequence can be performed in-situ within a single gate etch chamber.
