    摘要: The invention relates to a method of re-forming a useful layer on a donor wafer after taking off a useful layer formed of a material chosen from among semiconductor materials. The donor wafer includes in succession a substrate and a taking-off structure, the taking-off structure includes the taken-off useful layer before taking-off. The method includes a removal of material involving a portion of the donor wafer on the side where the useful layer has been taken off. The material is removed by mechanical means so as to preserve a portion of the taking-off structure to form at least one other useful layer which can be taken off after re-forming, without adding additional material to the wafer.

    摘要: An efficient method of fabricating a high-quality heteroepitaxial microstructure having a smooth surface. The method includes detaching a layer from a base structure to provide a carrier substrate having a detached surface, and then forming a heteroepitaxial microstructure on the detached surface of the carrier substrate by depositing an epitaxial layer on the detached surface of a carrier substrate. Also included is a heteroepitaxial microstructure fabricated from such method.
