Abstract:
1. A method of producing a lamina from a donor body, the method comprising the steps of: a. implanting a first surface of a donor body with an ion dosage to form a cleave plane; b. heating the donor body to an implant temperature during implanting; c. separably contacting the first surface of the donor body to a first surface of a susceptor assembly, wherein the first surface of the donor body and the first surface of the susceptor assembly are in direct contact; d. applying an exfoliation temperature to the donor body to exfoliate a lamina from the donor body at the cleave plane, wherein the first surface of the donor body comprises a first surface of the lamina; e. separating the lamina from the donor body; and f. adjusting the combination of dosage, implant temperature, exfoliation temperature and exfoliation pressure to maximize an area substantially free of physical defects in the lamina.
