       Large Die Backside Thinning with Minimal Thickness Variation


        UltraPrep is designed to perform in-package die thinning and polishing, plus       special machining functions for sample preparation. The die thnned and               polished   by UltraPrep are suited for all backside procedures because of the         surface   uniformity of the thinned and polished silicon.
