Abstract
A method for fabricating a semiconductor substrate. In an embodiment, this method includes the steps of transferring a seed layer on to a support substrate; and depositing a working layer on the seed layer to form a composite substrate. The seed layer is made of a material that accommodates thermal expansion of the support substrate and of the working layer. The result is a semiconductor substrate that includes the at least one layer of semiconductor material on a support substrate.
