Abstract
Reconditioned donor substrates that include 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 an additional layer deposited upon the opposite surface of the remainder substrate to increase its thickness and to form the reconditioned substrate. The reconditioned substrate is recycled as a donor substrate for fabricating compound material wafers and is typically made from gallium nitride donor substrates.
