  • Method for transferring a thin layer using a filled preceramic polymer
    Patent number: 11380577
    Abstract: A method for transferring, from a donor substrate to a carrier substrate, a thin layer having a first coefficient of thermal expansion. This method comprises: —forming an embrittlement plane in the donor substrate; —forming an electrically insulating layer on the surface of the donor substrate and/or of the carrier substrate; —producing an assembly by placing the donor substrate and the carrier substrate in contact with one another via the insulating layer; —separating the assembly by fracturing along the embrittlement plane.
    Type: Grant
