METHOD OF CLEAVING SUBSTRATE AND METHOD OF MANUFACTURING BONDED SUBSTRATE USING THE SAME

摘要

A method of cleaving a substrate and a method of manufacturing a bonded substrate using the same, in which warping in a cleaved substrate is reduced. The method includes the following steps of: forming an ion implantation layer by implanting ions into a substrate; annealing the substrate in which the ion implantation layer is formed; implanting ions again into the ion implantation layer of the substrate; and cleaving the substrate along the ion implantation layer by heating the substrate into which ions are implanted.
