    摘要: Methods are provided for fabricating semiconductor structures and semiconductor device structures utilizing epitaxial Hf3Si2 layers. A process in accordance with one embodiment of the invention begins by disposing a silicon substrate in a processing chamber. The pressure within the processing chamber and a temperature of the silicon substrate in the range of approximately 250° C. to approximately 700° C. is established. A layer of Hf3Si2 then is grown overlying the silicon substrate at a rate in the range of about one (1) to about five (5) monolayers per minute.

    摘要: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer has a lattice registry to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials. The layers of the semiconductor structure may be manufactured in such a way as to control the formation of anti-phase domains so that the structure may operate without the deleterious effects associated with such defects. Such manufacture may include heat treating the substrate to essentially or completely eliminate single steps (anti-phase domains) by forming double steps that can transfer to the oxide interface layer and suppress the formation of anti-phase domains by forming double step therein, in preference to single steps.
