Patent ID: 7294564

Claim:
A method for forming a layered semiconductor technology structure having a layer ( 5 ) of a first semiconductor technology material on a substrate ( 1 ; 1 ′) of at least one second semiconductor technology material, comprising the steps of: providing said substrate ( 1 ; 1 ′); burying said layer ( 5 ) of a first semiconductor technology material in said substrate ( 1 ; 1 ′), said buried layer ( 5 ) having an upper surface ( 105 ) and a lower surface ( 104 ) and dividing said substrate ( 1 ; 1 ′) into an upper part ( 1 a ) and a lower part ( 1 b ; 1 b ′; 1 c ); creating a buried damage layer ( 10 ; 10 ′; 10 ″; 100 ″) which at least partly adjoins and/or at least partly includes said upper surface ( 105 ) of said buried layer ( 5 ); and removing said upper part ( 1 a ) of said substrate ( 1 ; 1 ′) and said buried damage layer ( 10 ; 10 ′; 10 ″; 100 ″) for exposing said buried layer ( 5 ).
