Abstract:
An apparatus, device and method for wafer dicing is disclosed. In one example, the apparatus discloses: a wafer holding device having a first temperature; a die separation bar moveably coupled to the wafer holding device; and a cooling device coupled to the apparatus and having a second temperature which enables the die separation bar to fracture an attachment material in response to movement with respect to the wafer holding device. In another example, the method discloses: receiving a wafer having an attachment material applied to one side of the wafer; placing the wafer in a holding device having a first temperature; urging a die separation bar toward the wafer; and cooling the attachment material to a second temperature, which is lower than the first temperature, until the attachment material fractures in response to the urging.
