摘要:
In a method for producing a bonded wafer by bonding a wafer for active layer to wafer for support layer and then thinning the wafer for active layer, a terrace grinding for forming a terrace portion is carried out prior to a step of exposing the oxygen ion implanted layer to thereby leave an oxide film on a terrace portion of the wafer for support layer.
