Title: The Innovations of Kenneth MacWilliams: Pioneering Advances in Lithography
Introduction
Kenneth MacWilliams, based in Los Altos Hills, California, is a remarkable inventor whose contributions have significantly influenced the field of lithography. With a total of two patents to his name, he has focused his research on developing innovative methods that improve patterning technologies in substrate layers.
Latest Patents
MacWilliams' latest patents showcase his expertise in advanced lithography techniques. The first patent, titled "Double exposure patterning with carbonaceous hardmask," outlines methods to pattern features in a substrate layer by exposing a photoresist layer multiple times. In this approach, a single reticle can undergo multiple exposures with an overlay offset, subsequently enhancing the half pitch reductions of the reticle. This method is particularly useful in achieving superior 45 nm lithography generation CD and pitch performance, even while utilizing 65 nm generation lithography equipment.
The second patent, "Air gap formation and integration using a patterning cap," focuses on methods for patterning films and their resulting structures. This embodiment describes the process of forming an amorphous carbon mask over a substrate, followed by the deposition of a spacer layer. The innovative application results in selective removal of the amorphous carbon mask, paving the way for an efficient gap fill mask formation over the substrate.
