Title: Innovations by Fabrizio Leoni
Introduction
Fabrizio Leoni is a notable inventor based in Novara, Italy. He has made significant contributions to the field of semiconductor technology, holding three patents to his name. His work focuses on improving processes related to silicon wafers, which are essential components in the electronics industry.
Latest Patents
One of Leoni's latest patents is titled "Process for the removal of copper from polished boron doped silicon." This innovative process addresses the challenge of removing copper from a boron-doped, polished silicon wafer. The method involves annealing the wafer at a temperature of at least 75 degrees Celsius to enhance the concentration of copper on the polished surface while reducing it in the interior. Following this, the polished surface is cleaned to further decrease the copper concentration. Importantly, the annealing step is designed to ensure that the copper concentration does not increase significantly during storage.
Another significant patent by Leoni is the "Method and apparatus for automated quality control in wafer slicing." This invention introduces an internal diameter saw that enhances quality control during the slicing of semiconductor wafers from an ingot of source material. The saw is equipped with a controller that monitors the deflection of the cutting edge of the blade. Based on the detected deflection, a blade dressing device is automatically activated to sharpen the blade after each cut, ensuring consistent quality.
