ABSTRACT:
Even if an oxygen ion implanted layer in a wafer for active layer is not a completely continuous SiO2layer but a layer mixed partially with Si or SiOx, it is removed by here is provided a method for producing a bonded wafer in which it is possible to remove an oxygen ion implanted layer effectively as it is by repetitive treatment with an oxidizing solution and HF solution at a step of removing the oxygen ion implanted layer in a bonded wafer.
