    摘要: Fabricating a semiconductor includes depositing a metal layer outwardly from a dielectric layer and forming a mask layer outwardly from a first portion of the metal layer. Atoms are incorporated into an exposed second portion of the metal layer to form a composition-altered portion of the metal layer. The mask layer is removed from the first portion of the metal layer and a barrier layer is deposited outwardly from the metal layer. A poly-Si layer is deposited outwardly from the barrier layer to form a semiconductor layer, where the barrier layer substantially prevents reaction of the metal layer with the poly-Si layer. The semiconductor layer is etched to form gate stacks, where each gate stack operates according to one of a plurality of work functions.

    摘要: The present invention provides a system for producing a triple-gate transistor segment (300), utilizing a standard semiconductor substrate (302). The substrate has a plurality of isolation regions (304) formed along its upper surface in a distally separate relationship, defining a channel region (306). A form structure (308) is disposed atop the isolation regions, and defines a channel body area (310) over the channel region. A channel body structure (316) is disposed within the channel body area, and is engineered to provide a blunted corner or edge (318) along a perimeter of its upper exposed surface. The form structure is then removed, and subsequent processing is performed.

    摘要: Example embodiments provide triple-gate semiconductor devices isolated by reverse shallow trench isolation (STI) structures and methods for their manufacture. In an example process, stacked layers including a form layer over a dielectric layer can be formed over a semiconductor substrate. One or more trenches can be formed by etching through the stacked layers. The one or more trenches can be filled by an active area material to form one or more active areas, which can be isolated by remaining portions of the dielectric layer. Bodies of the active area material can be exposed by removing the form layer. One or more triple-gate devices can then be formed on the exposed active area material. The example triple-gate semiconductor devices can control the dimensions for the active areas and provide less isolation spacing between the active areas, which optimizes manufacturing efficiency and device integration quality.

    摘要: One embodiment relates to a method of fabricating an integrated circuit. In the method, p-type polysilicon is provided over a semiconductor body, where the p-type polysilicon has a first depth as measured from a top surface of the p-type polysilicon. An n-type dopant is implanted into the p-type polysilicon to form a counter-doped layer at the top-surface of the p-type polysilicon, where the counter-doped layer has a second depth that is less than the first depth. A catalyst metal is provided that associates with the counter-doped layer to form a catalytic surface. A metal is deposited over the catalytic surface. A thermal process is performed that reacts the metal with the p-type polysilicon in the presence of the catalytic surface to form a metal silicide. Other methods and devices are also disclosed.

    摘要: A method of manufacturing a semiconductor device includes forming transistors including gate electrodes and source/drain regions over a substrate. A protective layer is placed over the source/drain regions and the gate electrodes. A portion of the protective layer is removed to expose a portion of the gate electrodes. The exposed portions of the gate electrodes are amorphized, and remaining portions of the protective layer located over the source/drain regions are removed. A stress memorization layer is formed over the gate electrodes, and the substrate is annealed in the presence of the stress memorization layer to at least reduce an amorphous content of the gate electrodes. The stress memorization layer is removed subsequent to the annealing.

    摘要: An encapsulated gate structure includes a polysilicon layer, a barrier layer overlying the polysilicon layer and having opposing sidewalls, a metal layer overlying the barrier layer and having opposing sidewalls, a top dielectric layer overlying the metal layer and having opposing sidewalls, and a vertically oriented dielectric layer extending over and covering each of the opposing sidewalls of the barrier layer and the metal layer to encapsulate the barrier layer and metal layer on the polysilicon layer. The encapsulated gate and barrier layer are thus unaffected by oxidation and other similar detrimental effects of subsequent processing steps.
