The invention provides a method of forming an electronic device from a lamina that has a coefficient of thermal expansion that is matched or nearly matched to a constructed metal support. In some embodiments the method comprises implanting the top surface of a donor body with an ion dosage to form a cleave plane followed by exfoliating a lamina from the donor body. After exfoliating the lamina, a flexible metal support that has a coefficient of thermal expansion with a value that is within 10% of the value of the coefficient of thermal expansion of the lamina is constructed on the lamina. In some embodiments the coefficients of thermal expansion of the metal support and the lamina are within 10% or within 5% of each other between the temperatures of 100 and 600&#xb0; C.

Multi-layer metal support

A method for producing a lamina from a donor body includes implanting the donor body with an ion dosage and separably contacting the donor body with a susceptor assembly, where the donor body and the susceptor assembly are in direct contact. A lamina is exfoliated from the donor body, and a deforming force is applied to the lamina or to the donor body to separate the lamina from the donor body.

Method and apparatus for forming a thin lamina

A method for producing a lamina from a donor body includes implanting the donor body with an ion dosage and heating the donor body to an implant temperature during implanting. The donor body is separably contacted with a susceptor assembly, where the donor body and the susceptor assembly are in direct contact. A lamina is exfoliated from the donor body by applying a thermal profile to the donor body. Implantation and exfoliation conditions may be adjusted in order to maximize the defect-free area of the lamina.
