  • Method for curing defects in a semiconductor layer
    Patent number: 8993461
    Abstract: A method for curing defects associated with the implantation of atomic species into a semiconductor layer transferred onto a receiver substrate, wherein the semiconductor layer is thermally insulated from the receiver substrate by a low thermal conductivity layer having thermal conductivity that is lower than that of the transferred semiconductor layer. The method includes applying a selective electromagnetic irradiation to the semiconductor layer to heat that layer to a temperature lower than its temperature of fusion to cure defects without causing an increase in the temperature of the receiver substrate beyond 500° C.
    Type: Grant
    Filed: July 27, 2012
    Date of Patent: March 31, 2015
    Assignee: Soitec
    Inventors: Ionut Radu, Christophe Gourdel, Christelle Vetizou
