Abstract:
The invention relates to a method of treating a thin film transferred from a donor substrate to a receiver substrate by fracture at the level of a zone of the donor substrate which is made fragile by hydrogen ion implantation. The method includes a step of thinning the transferred thin film so as to eliminate a region of residual defects induced by the hydrogen ion implantation. The method also includes, directly after the fracture and before the step of thinning of the transferred thin film, a step of forming a hydrogen trapping layer in the region of residual defects of the transferred thin film. A thermal processing may be implemented after formation of the hydrogen trapping layer and before thinning of the thin film.

Claim (Index 1):
A method for treating a thin film transferred from a donor substrate to a receiver substrate by fracture at a zone of the donor substrate weakened by hydrogen ion implantation, the method comprising:\n directly after the fracture, forming a hydrogen trapping layer in a residual-defect region of the transferred thin film, and subsequently thinning the transferred thin film in order to eliminate the residual-defect region, wherein the thinning extends at least from a surface of the transferred thin film to the hydrogen trapping layer.
