    摘要: Semiconductor structures and methods for fabrication thereof are predicated upon epitaxial growth of an epitaxial surface semiconductor layer upon a semiconductor substrate having a first crystallographic orientation. The semiconductor substrate is exposed within an aperture within a semiconductor-on-insulator structure. The epitaxial surface semiconductor layer alternatively contacts or is isolated from a surface semiconductor layer having a second crystallographic orientation within the semiconductor-on-insulator structure. A recess of the semiconductor surface layer with respect to a buried dielectric layer thereunder and a hard mask layer thereover provides for inhibited second crystallographic phase growth within the epitaxial surface semiconductor layer.

    摘要: Accordingly, in one embodiment of the invention, a method is provided for reducing stacking faults in an epitaxial semiconductor layer. In accordance with such method, a substrate is provided which includes a first single-crystal semiconductor region including a first semiconductor material, the first semiconductor region having a crystal orientation. An epitaxial layer including the first semiconductor material is grown on the first semiconductor region, the epitaxial layer having the crystal orientation. The substrate is then annealed with the epitaxial layer at a temperature greater than 1100 degrees Celsius in an ambient including hydrogen, whereby the step of annealing reduces stacking faults in the epitaxial layer.
