A method is provided for producing a thin substrate with a thickness below 750 microns, comprising providing a mother substrate, the mother substrate having a first main surface and a toughness; inducing a stress with predetermined stress profile in at least a portion of the mother substrate, said portion comprising the thin substrate, the induced stress being locally larger than the toughness of the mother substrate at a first depth under the main surface; such that the thin substrate is released from the mother substrate, wherein the toughness of the mother substrate at the first depth is not lowered prior to inducing the stress. The method can be used in the production of, for example, solar cells.
