    摘要: A method is provided for fabricating an integrated semiconductor device. The method includes providing a semiconductor substrate having a first active region, a second active region and a plurality of isolation regions; forming a first gate dielectric layer on one surface of the semiconductor substrate; and forming a plurality of substituted gate electrodes, a layer of interlayer dielectric and sources/drains. The method also includes forming a first trench and a second trench; and covering the first gate dielectric layer on the bottom of the first trench. Further, the method includes removing the first dielectric layer on the bottom of the second trench; subsequently forming a second gate dielectric layer on the bottom of the second trench; and forming metal gates by filling the first trench and second trench using a high-K dielectric layer, followed by completely filling the first trench and the second trench using a gate metal layer.

    摘要: A fin field effect transistor (FET) including a fin structure and a method for forming the fin FET are provided. In an exemplary method, the fin FET can be formed by forming at least one fin seed, including a top surface and sidewalls, on a substrate. A first semiconductor layer can then be formed at least on the sidewalls of the at least one fin seed. A second semiconductor layer can be formed on the first semiconductor layer. The second semiconductor layer and the at least one fin seed can be made of a same material. The first semiconductor layer can be removed to form a fin structure including the at least one fin seed and the second semiconductor layer.
