Abstract:
A method of forming a plurality of semiconductor devices includes applying a tape material to a back side of a semiconductor device having a silicon layer on the back side and a circuitry layer on the front side, lasing with an infrared laser the silicon layer through the tape material, lasing with a second laser the circuitry layer, and expanding the tape material for form a plurality of semiconductor devices. The second layer may be an ultraviolet laser. The lasers may be irradiated in a pattern on the bottom side and the top side. The second layer may form a groove in the circuitry layer that does not penetrate the silicon layer. The infrared laser may cleave a portion of the silicon lattice of the silicon layer. A coating may be applied to the circuitry layer prior to being irradiated with the second laser.

Claim (Index 13):
An apparatus comprising:\n a handling system configured to manipulate a semiconductor device within the apparatus; a first laser chamber configured to receive the semiconductor device and lase with a first laser in a pattern through a tape material on a bottom surface of a semiconductor; a second laser chamber configured to receive the semiconductor device and cut a groove in accordance with the pattern in a circuity layer of the semiconductor device with a second laser; and an expansion chamber that expands the tape material on the bottom surface of the semiconductor to break the semiconductor device into a plurality of semiconductor devices in accordance with the pattern, wherein the handling system is configured to move the semiconductor device between the first laser chamber, the second laser chamber, and the expansion chamber.
