Abstract
The present invention provides a method of making a silicon on insulator (SOI) structure, comprising steps of: providing a bonded structure, the bonded structure comprises a first substrate, a second substrate and an insulating buried layer, the insulating buried layer is positioned between the first substrate and the second substrate; peeling off a layer of removing region of the first substrate from the bonded structure to obtain a SOI structure; and processing the SOI structure with isothermal annealing technology at a pressure which is lower than atmospheric pressure.
