  • Patent number: 9381548
    Abstract: A method of cleaning a die having an oxide layer is provided. The method includes discharging electromagnetic energy towards a working surface of the die having a layer of at least one of graphite and boron nitride thereon. The electromagnetic energy is discharged at a power output between about 6 kW and about 15 kW such that the layer of at least one of graphite and boron nitride is ablated, and such that the layer is removed without removing an oxide layer between the surface of the die and the layer.
