Abstract:
A method for determining a suitable implanting energy of at least two atomic species in a donor substrate to create a weakened zone defining a monocrystalline semiconductor layer to be transferred onto a receiver substrate, comprises the following steps: (i) forming a dielectric layer on at least one of the donor substrate and the receiver substrate; (ii) co-implanting the species in the donor substrate; (iii) bonding the donor substrate on the receiver substrate; (iv) detaching the donor substrate along the weakened zone to transfer the monocrystalline semiconductor layer and recover the remainder of the donor substrate; (v) inspecting the peripheral crown of the remainder of the donor substrate, or of the receiver substrate on which the monocrystalline semiconductor layer was transferred at step (iv); (vi) if the crown exhibits zones transferred onto the receiver substrate, determining the fact that the implanting energy at step (ii) is too high; (vii) if said the crown does not exhibit zones transferred onto the receiver substrate, determining the fact that the implanting energy at step (ii) is suitable.

Claim (Index 4):
A method for manufacturing a semiconductor-on-insulator structure via transfer of a monocrystalline semiconductor layer from a donor substrate to a receiver substrate, comprising the following steps:\n (a) determining a suitable implanting energy with the method according to  claim 3 ; (b) forming a dielectric layer on at least one of the receiver substrate and the donor substrate; (c) co-implanting atomic species, such as hydrogen and helium, with the implanting energy determined at step (a), to create a weakened zone in the donor substrate so as to define a monocrystalline semiconductor layer to be transferred; (d) molecularly bonding the donor substrate on a receiver substrate, said dielectric layer lying at the bonding interface; (e) detaching the donor substrate along the weakened zone, to transfer the monocrystalline semiconductor layer onto the receiver substrate.
