Latest Patents

One of Rolf Berndt's latest patents is a "Method for treating spent abrasive slurry." This invention addresses the treatment of spent abrasive slurry obtained from cutting a body of a substrate material into wafer-like slices. The method involves separating the spent slurry in a first sedimentation step into a solids concentrate comprising unspent abrasive particles and a solids depleted slurry. Subsequently, the solids depleted slurry is separated by cross-flow filtration into a fines containing fraction and a solids and fines depleted regenerated lubricant fluid.

Another significant patent is the "Method and system for manufacturing wafer-like slices from a substrate material." This invention relates to a method and system specifically designed for the manufacture of wafer-like slices from a body of substrate material, particularly for use in semiconductor devices. The method includes providing a slicing device with a cutting wire equipped with abrasive particles, along with an aqueous cooling and lubricating fluid. This fluid promotes the removal of powdered substrate material from the kerf area during the cutting process, resulting in the recovery of powdered substrate material from the spent fluid.
