A method for producing a semiconductor entity is described. The method
includes providing a donor substrate having a zone of weakness at a
predetermined depth to define a thin layer, and the donor substrate
includes a bonding interface. A receiver substrate is also provided that
includes at least one motif on its surface. The technique further
includes bonding the donor substrate at the bonding interface to the at
least one motif on the receiver substrate, and supplying sufficient
energy to detach a portion of the thin layer from the donor substrate
located at the at least one motif and to rupture bonds within the thin
layer. The energy thus supplied is insufficient to rupture the bond at
the bonding interface. Also described is fabrication of a wafer and the
use of the method to produce chips suitable for use in electronics,
optics, or optoelectronics applications.
