ABSTRACT:
Methods are provided for producing a transfer layer of a semiconductor material on a final substrate. In some embodiments, the transfer layer is produced on the final substrate by forming a layer of semiconductor material on an initial support, assembling that layer and a final substrate by metal bonding, and mechanically separating the initial support from the layer at a weak interface that initially attached the layer to the initial support. An intermediate substrate can be obtained which can be used to fabricate a variety of components such as light-emitting diodes or laser diodes. These techniques can produce a transfer layer on a final substrate and a recyclable initial support that can be detached from the transfer layer for recycling by dint of non-destructive mechanical release.
