Abstract
A stressor layer is applied to a semiconducting stack in order to separate the semiconducting stack at a predetermined depth. Tensile force is applied to the stressor layer, fracturing the semiconducting stack at the predetermined depth and allowing the resulting upper portion of the semiconducting stack to be used in manufacturing a semiconducting end-product (e.g., a light-emitting diode). The resulting lower portion of the semiconducting stack may be reused to grow a new semiconducting stack thereon.
