METHOD FOR REDUCING IRREGULARITIES AT THE SURFACE OF A LAYER TRANSFERRED FROM A SOURCE SUBSTRATE TO A GLASS-BASED SUPPORT SUBSTRATE

摘要

The present invention concerns a method for reducing irregularities at the surface of a layer (4) transferred from a source substrate (1) to a glass-based support substrate (3), wherein said transfer comprises the steps of: (a) generating a weakening zone (2) in the source substrate (1); (b) contacting the source substrate (1) and the glass-based support substrate (3); (c) splitting the source substrate (1) at the weakening zone (2); characterized in that the thickness of the glass-based substrate is comprised between 300 µm and 600 µm.
