    摘要: In a method of producing a bipolar transistor, a semiconductor substrate having a substrate surface is provided. A base-terminal layer for providing a base terminal is formed on the substrate surface, and an emitter window having a wall area is formed in the base-terminal layer. A first spacing layer is formed on the wall area of the emitter contact window, and a recess is etched into the substrate within a window specified by the first spacing layer. A base layer contacted by outdiffusion from the base-terminal layer is formed in the recess of the emitter window, and a second spacing layer is formed on the first spacing layer and on the base layer. The second spacing layer is structured for the purpose of specifying a planar terminal pad on the base layer, and an emitter layer is formed on the planar terminal pad.

    摘要: A multi-layer gate stack structure of a field-effect transistor device is fabricated by providing a gate electrode layer stack with a polysilicon layer, a transition metal interface layer, a nitride barrier layer and then a metal layer on a gate dielectric, wherein the transition metal is titanium, tantalum or cobalt. Patterning the gate electrode layer stack comprises a step of patterning the metal layer and the barrier layer with an etch stop on the surface of the interface layer. Exposed portions of the interface layer are removed and the remaining portions are pulled back from the sidewalls of the gate stack structure leaving divots extending along the sidewalls of the gate stack structure between the barrier layer and the polysilicon layer. A nitride liner encapsulating the metal layer, the barrier layer and the interface layer fills the divots left by the pulled-back interface layer. The nitride liner is opened before the polysilicon layer is patterned. As the requirement for an overetch into the polysilicon layer during the etch of the metal layer, the barrier layer and the interface layer is omitted, the height of the polysilicon layer can be reduced. The aspect ration of the gate stack structure is improved, the feasibility of pattern and fill processes enhanced and the range of an angle under which implants can be performed is extended.

    摘要: Ni and Pt residuals are eliminated by replacing an SPM cleaning process with application of HNO3 in an SWC tool. Embodiments include depositing a layer of Ni/Pt on a semiconductor substrate, annealing the deposited Ni/Pt layer, removing unreacted Ni from the annealed Ni/Pt layer by applying HNO3 to the annealed Ni/Pt layer in an SWC tool, annealing the Ni removed Ni/Pt layer, and removing unreacted Pt from the annealed Ni removed Ni/Pt layer. Embodiments include forming first and second gate electrodes on a substrate, spacers on opposite sides of each gate electrode, and Pt-containing NiSi on the substrate adjacent each spacer, etching back the spacers, forming a tensile strain layer over the first gate electrode, applying a first HNO3 in an SWC tool, forming a compressive strain layer over the second gate electrode, and applying a second HNO3 in an SWC tool.
