摘要: In one example, a method of epitaxially forming a silicon-containing material on a substrate surface is presented which includes positioning a substrate into a process chamber. The substrate has a monocrystalline surface and at least a second surface, such as an amorphous surface and/or a polycrystalline surface. The substrate is exposed to a deposition gas to deposit an epitaxial layer on the monocrystalline surface and a polycrystalline layer on the second surface. The deposition gas preferably contains a silicon source and at least a second elemental source, such as a germanium source, a carbon source and/or combinations thereof. Thereafter, the method further provides exposing the substrate to an etchant gas to etch the polycrystalline layer and the epitaxial layer in a manner such that the polycrystalline layer is etched at a faster rate than the epitaxial layer. The method may further include a deposition cycle that includes repeating the exposure of the substrate to the deposition and etchant gases to form a silicon-containing material with a predetermined thickness.

摘要: A novel growth procedure to grow epitaxial Group III metal nitride thin films on lattice-mismatched substrates is proposed. Demonstrated are the quality improvement of epitaxial GaN layers using a pure metallic Ga buffer layer on c-plane sapphire substrate. X-ray rocking curve results indicate that the layers had excellent structural properties. The electron Hall mobility increases to an outstandingly high value of &mgr;>400 cm2/Vs for an electron background concentration of 4×1017 cm−3.
