Crystal Boule Grinder
Crystal boule grinders shape semiconductor boules to precise diameters and grind flats that indicate conductivity type and resistivity. This preparation step is essential before slicing the boule into wafers for semiconductor device manufacturing. The grinder is a machine used solely or principally for the manufacture of semiconductor boules.
