Also hell of a lot cheaper when you can reuse the glass (instead of rejecting it for a metal defect) by stripping the photoresist and re-coating for writing a new pattern.
Since photoresists naturally absorb at the right wavelength, why not just use the photoresist as the masking layer? Forget etching the metal...
