Title: The Innovations of Heinz F. Reinhardt
Introduction
Heinz F. Reinhardt is a notable inventor based in Chadds Ford, Pennsylvania, with a remarkable portfolio of 17 patents. His work primarily focuses on advancements in polishing compositions and methods, particularly for noble metals and semiconductor devices.
Latest Patents
One of Reinhardt's latest patents is for polishing compositions for noble metals. This invention is particularly useful for chemical-mechanical polishing of substrates containing noble metals such as platinum. The composition includes up to about 50% by weight of an adjuvant, which can be a metal-anion compound, a metal-cation compound, or mixtures thereof. Additionally, it contains abrasive particles ranging from about 0.5% to about 55% by weight, selected from materials like alumina, ceria, and diamond. The inclusion of water-soluble organic additives, up to about 10% by weight, enhances the dispersion of abrasive particles and improves metal removal rates.
Another significant patent involves a method of polishing a semiconductor device. This method utilizes a polishing pad made of a polymeric matrix and a dissolvable substance. The dissolvable substance is strategically located at the work surface and subsurface of the polishing pad. As the semiconductor device is polished, the dissolvable substance dissolves, allowing the subsurface to become a new work surface, thereby continuing the polishing process effectively.
