A semiconductor substrate that includes a relatively thin monocrystalline
useful layer, an intermediate layer transferred from a source substrate,
and a relatively thick layer of a support present on one of the useful
layer of the intermediate layer. The support is made of a deposited
material that has a lower quality than that of one or both of the
intermediate and useful layers. A bonding layer may be included on one of
the intermediate layer or the useful layer, or both, to facilitate
bonding of the layers an a thin layer may be provided between the useful
layer and intermediate layer. These final substrates are useful in optic,
electronic, or optoelectronic applications.
