Abstract:
The present disclosure provides an annealing method for improving interface bonding strength of a wafer. The method includes: providing a substrate, the substrate having a bonding interface; performing a first annealing step, wherein the first annealing step is practiced in an oxygen-containing atmosphere, and an oxidation protection layer is formed on a surface of the substrate through the annealing step; 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, and the second annealing step is practiced in a nitrogen-free environment.

Claim (Index 3):
The annealing method for improving interface bonding strength of a wafer according to  claim 1 , wherein the second annealing step is performed within a temperature range of 1000\u00b0 C. to 1350\u00b0 C.
