It is easy to overlook the role lithography plays in developing digital technologies. Every year, new and more advanced integrated circuits appear, pushing computing capabilities to more advanced levels. Typically, the focus is on what these devices can do, in areas like supercomputing, artificial intelligence (AI), and wireless communications, for example. Yet, behind the curtain is the technology that makes all of this possible. Lithography--which at its most basic level refers to a photography-like process that uses light to imprint images on a suitable substrate, such as a thin film--is at the foundation of modern computing and electronics.
