Preparation for Photoemission

  • Thinning of backside samples using mechanical grinding and polishing

  • Process large (> 25 X 25 mm), highly curved, packaged die to less than 3 microns remaining silicon thickness with uniformity of 1.5 micron

  • The VarioMill facilitates rapid failure analysis with less residual stress and damage to the underlying circuits than any other technology
