Patent ID: 8261730

Claim:
An integrated wafer processing system, comprising: a wire sawing apparatus, wherein the wire sawing apparatus comprises: a wire web, wherein at least one work piece is impelled against the wire web; and at least one first top outlet and at least one second top outlet for applying fluids during sawing, wherein the fluids comprise an abrasive slurry and at least one cleaning fluid, wherein the at least one first top outlet being located in a top position with respect to the at least one work piece, wherein the fluids flow in a substantially downward vertical direction under a gravitational force and wherein the at least one first top outlet supplies the abrasive slurry to the at least one work piece and the abrasive slurry flows into the at least one work piece for slicing and resulting in wafer stack of cut wafers held integrally by an uncut portion or by a welded plate and the at least one second top outlet supplies the at least one cleaning fluid, wherein the at least one second top outlet being located and oriented to substantially spray the at least one cleaning fluid over the wafers for cleaning as the cut wafers emerge from the wire web.
