    摘要: A method and system for performing metal-organic chemical vapor deposition (MOCVD). The method introduces a metal-organic compound into the CVD chamber in the presence of a first reactant selected to have a reducing chemistry and then, subsequently, a second reactant selected to have an oxidizing chemistry. The reducing chemistry results in deposition of metal species having a reduced surface mobility creating more uniform coverage and better adhesion. The oxidizing species results in deposition of metal species having a greater surface mobility leading to greater surface agglomeration and faster growth. By alternating the two reacts, faster growth is achieved and uniformity of the metal structure is enhanced.

    摘要: A plug is formed of polysilicon, or other oxidizable conductor. Chemical-mechanical polishing is performed, with a polish stop layer defining the top of the dielectric layer. The upper portion of the polysilicon is oxidized to a controlled depth, then the oxidized portion is removed by an etch, followed by removal of the polish stop layer. The plug thus formed protrudes a controllable distance above the surrounding dielectric, providing good contact to subsequent conductive layers.

    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.
