    摘要: A method of forming a semiconductor structure which includes an extremely thin silicon-on-insulator (ETSOI) semiconductor structure having a PFET portion and an NFET portion, a gate structure in the PFET portion and the NFET portion, a high quality nitride spacer adjacent to the gate structures in the PFET portion and the NFET portion and a doped faceted epitaxial silicon germanium raised source/drain (RSD) in the PFET portion. An amorphous silicon layer is formed on the RSD in the PFET portion. A faceted epitaxial silicon RSD is formed on the ETSOI adjacent to the high quality nitride in the NFET portion. The amorphous layer in the PFET portion prevents epitaxial growth in the PFET portion during formation of the RSD in the NFET portion. Extensions are ion implanted into the ETSOI underneath the gate structure in the NFET portion.

    摘要: A method of fabricating a semiconductor device is provided in which the channel of the device is present in an extremely thin silicon on insulator (ETSOI) layer, i.e., a silicon containing layer having a thickness of less than 10.0 nm. In one embodiment, the method may begin with providing a substrate having at least a first semiconductor layer overlying a dielectric layer, wherein the first semiconductor layer has a thickness of less than 10.0 nm. A gate structure is formed directly on the first semiconductor layer. A in-situ doped semiconductor material is formed on the first semiconductor layer adjacent to the gate structure. The dopant from the in-situ doped semiconductor material is then diffused into the first semiconductor layer to form extension regions. The method is also applicable to finFET structures.

    摘要: A semiconductor device and a method of fabricating a semiconductor device are disclosed. In one embodiment, the method comprises providing a semiconductor substrate, epitaxially growing a Ge layer on the substrate, and epitaxially growing a semiconductor layer on the Ge layer, where the semiconductor layer has a thickness of 10 nm or less. This method further comprises removing at least a portion of the Ge layer to form a void beneath the Si layer, and filling the void at least partially with a dielectric material. In this way, the semiconductor layer becomes an extremely thin semiconductor-on-insulator layer. In one embodiment, after the void is filled with the dielectric material, in-situ doped source and drain regions are grown on the semiconductor layer. In one embodiment, the method further comprises annealing said source and drain regions to form doped extension regions in the semiconductor layer. Epitaxially growing the extremely thin semiconductor layer on the Ge layer ensures good thickness control across the wafer. This process could be used for SOI or bulk wafers.

    摘要: Disclosed is an improved double patterning method for forming openings (e.g., vias or trenches) or mesas on a substrate. This method avoids the wafer topography effects seen in prior art double patterning techniques by ensuring that the substrate itself is only subjected to a single etch process. Specifically, in the method, a first mask layer is formed on the substrate and processed such that it has a doped region and multiple undoped regions within the doped region. Then, either the undoped regions or the doped region can be selectively removed in order to form a mask pattern above the substrate. Once the mask pattern is formed, an etch process can be performed to transfer the mask pattern into the substrate. Depending upon whether the undoped regions are removed or the doped region is removed, the mask pattern will form openings (e.g., vias or trenches) or mesas, respectively, on the substrate.
