A method for spalling a layer from an ingot of a semiconductor substrate includes forming a metal layer on the ingot of the semiconductor substrate, wherein a tensile stress in the metal layer is configured to cause a fracture in the ingot; and removing the layer from the ingot at the fracture. A system for spalling a layer from an ingot of a semiconductor substrate includes a metal layer formed on the ingot of the semiconductor substrate, wherein a tensile stress in the metal layer is configured to cause a fracture in the ingot, and wherein the layer is configured to be removed from the ingot at the fracture.
