Abstract
Methods are disclosed for preparing a reconditioned donor substrate by providing a remainder substrate from a donor substrate wherein the remainder substrate has a detachment surface where a transfer layer was detached and an opposite surface; and depositing an additional layer onto the opposite surface of the remainder substrate to increase its thickness and to form a reconditioned substrate. The reconditioned substrate is recycled as a donor substrate for fabricating compound material wafers.
