The following invention provides a method for forming a layered semiconductor structure having a layer of a first semiconductor material on a substrate of at least one second semiconductor material, comprising the steps of: providing said substrate; burying said layer of said first semiconductor material in said substrate, said buried layer having an upper surface and a lower surface and dividing said substrate into an upper part and a lower part; creating a buried damage layer; which at least partly adjoins and/or partly includes said upper surface of said buried layer; and removing said upper part of said substrate and said buried damage layer for exposing said buried layer. The invention also provides a corresponding layered semiconductor structure.
