A method of fabrication of a substrate for an epitaxial growth

摘要

The present invention relates to a method of fabrication of a substrate for an epitaxial growth, comprising: obtaining a relaxed epitaxial base layer on an auxiliary substrate. It is the object of the present invention to fabricate substrates which allow for more efficient epitaxial growth of a material with a desired lattice parameter on another material with a different lattice parameter, wherein the material can be grown with a high thermodynamic and crystallographic stability. The object is solved by a method of the above-mentioned type which further comprises: transferring at least a part of the epitaxial base layer onto a carrier substrate, forming a base substrate; and further growing of the material of the epitaxial base layer on the carrier substrate.
