Abstract:
A method for integrating heterogeneous elements with elements residing on a target wafer is described. A source die including a compound semiconductor substrate, an etch stop layer and at least one active semiconductor element is provided. The etch stop layer is between the active semiconductor element(s) and the substrate. The etch stop layer is resistant to a plasma etch for the substrate. A bonding agent is provided on a surface of the target wafer. The source die is aligned to and placed on the part of the surface of the target wafer such that the active semiconductor element(s) are between the target wafer's surface and the substrate. The bonding agent is between the source die and the surface of the target wafer. The source die is bonded to the target wafer using the bonding agent. The substrate of the source die is removed, the removal includes performing the plasma etch.

Claim (Index 1):
A method for integrating heterogeneous elements with circuit elements residing on a target wafer comprising:\n providing a source die including a compound semiconductor (CS) substrate, an etch stop layer and at least one active semiconductor element, the etch stop layer residing between the at least one active semiconductor element and the CS substrate, the etch stop layer being resistant to a plasma etch for removing the CS substrate; providing a bonding agent on at least a portion of a surface of the target wafer; aligning the source die to the portion of the surface of the target wafer; placing the source die on the portion of the surface of the target wafer such that the at least one active semiconductor element is between the surface of the target wafer and the CS substrate, at least a portion of the bonding agent residing between the source die and the surface of the target wafer; bonding the source die to the surface of the target wafer using the bonding agent; and removing the CS substrate of the source, a portion of the removing step including performing the plasma etch.
