Abstract:
The present disclosure provides a method for preparing a substrate with a carrier trapping center. The method includes: injecting bubbling ions into the semiconductor substrate to form a splitting layer, and injecting modified ions into the insulating layer to form a nano cluster; providing a supporting substrate; bonding the supporting substrate to the semiconductor substrate by using the insulating layer as an intermediate layer; performing a first heat treatment for the bonded substrate such that a splitting layer is formed at the position where the bubbling ions are injected, and causing the semiconductor substrate to split at the position of the splitting layer; thinning a splitting surface of the split semiconductor substrate; and performing a second heat treatment for the thinned semiconductor substrate to consolidate the bonding interface and form the nano cluster at the position where the modified ions are injected.

Claim (Index 3):
The method for preparing a substrate with a carrier trapping center according to  claim 1 , wherein the second heat treatment further comprises:\n performing a first annealing step, wherein the first annealing step is practiced in an oxygen-containing atmosphere, and an oxidation layer is formed on a surface of the substrate through the annealing step, the oxidation layer having a thickness of greater than 40 nm; and performing a second annealing step upon the first annealing step, wherein a temperature of the second annealing step is higher than that of the first annealing step.
