Introduction

Herbert Jacob is a notable inventor based in Burghausen, Germany. He has made significant contributions to the field of semiconductor technology, particularly in the polishing processes of semiconductor wafers. With a total of 5 patents to his name, Jacob's work has had a profound impact on the efficiency and quality of semiconductor manufacturing.

Latest Patents

Jacob's latest patents include a method of haze-free polishing for semiconductor wafers. This innovative polishing process allows for the production of haze-free semiconductor wafers in a single-stage operation. The initial phase of polishing is conducted in the alkaline region, followed by a final phase at a pH of 3 to 7. This final phase utilizes additives in the polishing agent that minimize material removal, potentially eliminating the need for mechanically acting polishing agent components. Both phases can be executed on the same equipment without interrupting the polishing operation.

Another significant patent is the process for polishing silicon wafers. This process involves a last polishing step that creates a protective film of silicon dioxide on the surface of the polished wafer. This protective film does not interfere with subsequent oxidation processes and safeguards the wafer surface from various effects that could negatively impact surface quality.
