    Abstract: A method includes recessing a portion of a semiconductor substrate between opposite isolation regions to form a recess. After the step of recessing, the portion of the semiconductor substrate includes a top surface. The top surface includes a flat surface, and a slant surface having a (111) surface plane. The slant surface has a bottom edge connected to the flat surface, and a top edge connected to one of the isolation regions. The method further includes performing an epitaxy to grow a semiconductor material in the recess, wherein the semiconductor material is grown from the flat surface and the slant surface, and performing an annealing on the semiconductor material.

    Abstract: A structure includes a semiconductor substrate including a first semiconductor material. A portion of the semiconductor substrate extends between insulation regions in the semiconductor substrate. The portion of the semiconductor substrate has a (111) surface and a bottom surface. The (111) surface is slanted and has a top edge and a bottom edge. The bottom surface is parallel to a top surface of the insulation regions, and is connected to the bottom edge. A semiconductor region overlaps the portion of the semiconductor substrate, wherein the semiconductor region includes a second semiconductor material different from the first semiconductor material. The top edge and the bottom edge of the (111) surface are at a first depth and a second depth, respectively, relative to a top surface of the semiconductor region. A ratio of the first depth to the second depth is smaller than about 0.6.

    Abstract: A device including a silicon substrate, a silicon germanium layer, a silicon layer, a gate stack, and silicon-containing stressors is provided. In an embodiment, the silicon germanium layer is disposed over a silicon substrate and relaxed while the silicon layer is disposed over the silicon germanium layer and un-relaxed. The silicon layer may be free from germanium. The gate stack is of an n-type metal-oxide-semiconductor (NMOS) field-effect transistor (FET) and disposed over the silicon layer and the silicon germanium layer. A portion of the silicon layer forms a channel region of the NMOS FET. The silicon-containing stressors are formed in recesses in the silicon layer and have a lattice constant smaller than a lattice constant of the silicon germanium layer.
