    摘要: A method of forming a semiconductor device includes the following steps. A semiconductor substrate having a first strained silicon layer is provided. Then, an insulating region such as a shallow trench isolation (STI) is formed, where a depth of the insulating region is substantially larger than a depth of the first strained silicon layer. Subsequently, the first strained silicon layer is removed, and a second strained silicon layer is formed to substitute the first strained silicon layer.

    摘要: A semiconductor process is described as follows. A plurality of dummy patterns is formed on a substrate. A mask material layer is conformally formed on the substrate, so as to cover the dummy patterns. The mask material layer has an etching rate different from that of the dummy patterns. A portion of the mask material layer is removed, so as to form a mask layer on respective sidewalls of each dummy pattern. An upper surface of the mask layer and an upper surface of each dummy pattern are substantially coplanar. The dummy patterns are removed. A portion of the substrate is removed using the mask layer as a mask, so as to form a plurality of fin structures and a plurality of trenches alternately arranged in the substrate. The mask layer is removed.

    摘要: A manufacturing method of a metal gate structure includes providing a substrate having at least a first metal oxide layer formed thereon, and transferring the surface of the first metal oxide layer into a second metal oxide layer. The first metal oxide layer includes a metal oxide (M1Ox) of a first metal (M1) and the second metal oxide layer includes a metal oxide ((M1M2Oy) of the first metal and a second metal (M2).

    摘要: A method for forming a metal gate is provided. First, a dummy material is formed to completely cover a substrate. Second, a dopant is selectively implanted into the dummy material. Then, some of the dummy material is removed to expose part of the substrate and to form a dummy gate including a dopant region disposed between a first region and a second region. Later an interlayer dielectric layer is formed to surround the dummy gate. Next, a selective etching step is carried out to remove the first region to form a recess without substantially removing the dopant region. Afterwards, the recess is filled with a material set to form a metal gate.
