Title: The Innovative Contributions of Jack Griswold
Introduction
Jack Griswold is an accomplished inventor based in San Jose, California. Known for his significant contributions to the field of materials engineering, he has developed a unique patent focused on enhancing the properties of metal films through a physical vapor deposition (PVD) sputtering process.
Latest Patents
Griswold holds a patent for a PVD deposition process that enhances the preferred orientation of titanium layers. This innovative method involves the use of hydrogen before or during the deposition process to facilitate the creation of a titanium layer that, when used as a base for a titanium, titanium nitride, and aluminum interconnect stack, results in an aluminum layer exhibiting a predominant <111> crystallographic orientation. This characteristic provides improved resistance to electromigration, a critical factor in the reliability of electronic components. The process not only explores the use of a mixture of inert gas, typically argon, and hydrogen as sputtering gas but also presents a two-step titanium deposition procedure that utilizes bursts of hydrogen, making it broadly applicable for metallization layers.
