Making computer chips smaller is not just about better design. It also depends on a critical step in manufacturing called patterning, where nanoscale structures are carved into materials to form the circuits inside everything from smartphones to advanced sensors.  

To create these patterns, engineers use a hard mask, a thin, durable material layer that protects selected regions while the exposed areas are etched away.

Despite rare earth elements’ importance in manufacturing cell phones, magnets and a host of other consumer and commercial electronics, the lack of a sustainable, environmentally friendly approach to obtaining these metals has led to a global shortage, according to Amir Sheikhi, associate professor of chemical engineering.
