  • Publication number: 20230386896
    Abstract: A method for fabricating a strained semiconductor-on-insulator substrate comprises bonding a donor substrate to a receiving substrate with a dielectric layer at the interface. The donor substrate comprises a monocrystalline carrier substrate, an intermediate etch-stop layer, and a monocrystalline semiconductor layer. The monocrystalline semiconductor layer is transferred from the donor substrate to the receiving substrate. Trench isolations are formed to cut a portion from a layer stack including the transferred monocrystalline semiconductor layer, the dielectric layer, and the strained semiconductor material layer. The cutting operation results in relaxation of strain in the strained semiconductor material, and in application of strain to the transferred monocrystalline semiconductor layer.

  • Patent number: 10672646
    Abstract: A method for fabricating a strained semiconductor-on-insulator substrate includes bonding a donor substrate to a receiving substrate, with a dielectric layer at the interface, and transferring a monocrystalline semiconductor layer from the donor substrate to the receiving substrate. A portion is cut from a stack formed from the transferred monocrystalline semiconductor layer from the dielectric layer and from the strained semiconductor material layer. The cutting results in the relaxation of the strain in the strained semiconductor material, and in the application of at least a part of the strain to the transferred monocrystalline semiconductor layer. The method also involves the formation, on the strained semiconductor material layer of the receiving substrate, of a dielectric bonding layer or of a bonding layer consisting of the same relaxed, or at least partially relaxed, monocrystalline material as the monocrystalline semiconductor layer of the donor substrate.

  • Patent number: 9799549
    Abstract: The disclosure relates to a process for manufacturing a composite structure, the process comprising the following steps: a) providing a donor substrate and a carrier substrate; b) forming a dielectric layer; c) forming a covering layer; d) forming a weakened zone in the donor substrate; e) joining the carrier substrate and the donor substrate via a contact surface having an outline; f) fracturing the donor substrate via the weakened zone, steps b) and e) being executed so that the outline is inscribed in the outline, and step c) being executed so that the covering layer covers the peripheral surface of the dielectric layer.
