摘要： The present invention provides a method for manufacturing a bonded wafer comprising steps of forming an oxide film on at least a surface of a base wafer or a surface of a bond wafer; bringing the base wafer and the bond wafer into close contact via the oxide film; subjecting these wafers to a heat treatment under an oxidizing atmosphere to bond the wafers together; grinding and removing the outer periphery of the bond wafer so that the outer periphery has a predetermined thickness; subsequently removing an unbonded portion of the outer periphery of the bond wafer by etching; and then thinning the bond wafer so that the bond wafer has a desired thickness, wherein the etching is conducted by using a mixed acid at 30° C. or less at least comprising hydrofluoric acid, nitric acid, and acetic acid. Thus there is provided a method for manufacturing a bonded wafer by which unbonded portions of the outer periphery of the bond wafer are removed with a high selectivity ratio (RSi/RSiO2) without causing metallic contamination.

摘要： The present invention provides a method for manufacturing a bonded wafer, which includes at least the steps of bonding a bond wafer and a base wafer, grinding an outer peripheral portion of the bonded bond wafer, etching off an unbonded portion of the ground bond wafer, and then reducing a thickness of the bond wafer, wherein, in the step of grinding the outer peripheral portion, the bonded bond wafer is ground so as to form a groove along the outer peripheral portion of the bond wafer to form an outer edge portion outside the groove; and in the subsequent step of etching, the outer edge portion is removed together with the groove portion of the bond wafer to form a terrace portion where the base wafer is exposed at the outer peripheral portion of the bonded wafer. Thus, it is possible to provide a method for manufacturing a bonded wafer, which can reduce the number of dimples formed in a terrace portion of a base wafer upon removing an outer peripheral portion of a bonded bond wafer.
