Claim 16:
17. A substrate processing system, comprising:
a process chamber; and
a clamp apparatus, comprising:
an electrostatic clamp, disposed in the process chamber, the electrostatic clamp to clamp a substrate when the electrostatic clamp is arranged opposing a back side of the substrate; and

an illumination system, disposed to direct radiation to a front side of the substrate, opposite the back side of the substrate, when the substrate is disposed on the electrostatic clamp, wherein the radiation comprises a radiation energy, the radiation energy being equal to or above 2.5 eV, wherein the radiation is provided: by a combination of scanning the substrate and scanning an illumination source.
