Abstract:
1. A method comprising: forming a cleave plane in a donor body so as to define a lamina to be bonded to a receiver element and exfoliated from the donor body; after forming the cleave plane, pre-heating the donor body in a first chamber in an inert environment for a first time period that is less than a time period required for exfoliation of the lamina from the donor body, wherein the first chamber is a batch chamber capable of pre-heating two or more donor bodies at once, wherein pre-heating is performed at a temperature in the range from about 350 to about 500° C.; after pre-heating the donor body, heating the donor body and the receiver element in a second chamber; bonding the donor body to the receiver element within the second chamber; and heating the bonded donor body and receiver element for a second time period so as to complete the exfoliation of the lamina from the donor body; wherein the first time period is from about 5 minutes to about 4 hours and wherein the second time period is from about 2 to about 60 minutes.
