Latest Patents

Guillaume Berre's latest patents include innovative methods that enhance the efficiency of semiconductor layer transfers. The first patent describes a method for transferring a thin layer onto a receiver substrate that includes cavities and a region devoid of cavities. This method involves putting the donor substrate and the bonding face of the receiver substrate in contact, producing an assembly wherein the cavities are buried, and separating the assembly by fracture along a weakening plane. The bonding face of the receiver substrate features a bonding surface that comes into contact with the donor substrate, which includes a region devoid of cavities and an intercavity space that occupies a significant portion of the bonding face.

The second patent outlines a method for suspending a thin layer on a cavity with a stiffening effect obtained by pressurizing the cavity with implanted species. This method also involves forming an embrittlement plane in the donor substrate and creating a packaging in which the cavity is buried. The separation of the packaging results in the transfer of the semiconductor layer to the receiver substrate while sealing the cavity with the semiconductor layer.
