Abstract
In one embodiment, semiconductor die are singulated from a semiconductor wafer having a backmetal layer by placing the semiconductor wafer onto a carrier tape with the backmetal layer adjacent the carrier tape, forming singulation lines through the semiconductor wafer to expose the backmetal layer within the singulation lines, and separating portions of the backmetal layer within the singulation lines using a pressurized fluid applied to the carrier tape.
