Patent ID: 6974521

Claim:
A method for separating a monocrystalline film and a substrate wherein a sacrificial layer is provided between the film and the substrate, the method comprising the following steps: a) on the film at least a part of a foil is provided, whereby an adhesive contact between the film and the foil is effected; b) the foil and the film being in adhesive contact therewith are bent away from the substrate; and c) the film is uninterruptedly separated from the substrate, wherein the sacrificial layer is at least partly removed at least during step c) with the aid of etching, thereby facilitating the separation of the film from the substrate, characterized in that at least a part of the foil is attached to a circumferential surface of a roller, which circumferential surface virtually touches the substrate, and wherein during step b) the substrate with the film, relative to the roller, is fed to the roller, while the roller is rotated such that during step c) an increasing part of the film is bent around the circumferential surface, while an increasing part of the substrate from which the film has been separated is led, relative to the roller, away from the roller.
