Abstract
The invention relates to a method of thinning a block transferred to a substrate. According to the invention, the method includes depositing a stop layer at least onto the substrate and in a way adjacent to and contiguous with the transferred block. The stop layer is made out of material of greater resistance or hardness than the material of the transferred block and of smaller thickness than that of the transferred block. The method further includes actuating the thinning of the transferred block. The thinning time is pre-programmed as a function of a predetermined speed of thinning the transferred block, the thinning time being selected so that the thinning also attacks the stop layer.
