World's First Ferroelectric Nitride by Plasma-Enhanced Atomic Layer Deposition
The team at Kurt J. Lesker Company just published a paper in Communications Materials on ferroelectric AlScN by plasma-enhanced ALD under ultrahigh purity conditions. While traditional PVD approaches struggle with high-aspect-ratio architectures, this study shows how PEALD enables precise, uniform, and device-ready ferroelectric films.

Collaborative Success Stories

“As a long time Lesker customer, I have always been happy with their products and services. Recently, I had the opportunity to use their new Mag Keeper sputtering source and was very impressed with its overall performance. Having used TORUS magnetrons in the past, I found that the new design enabled me to run at much lower operating pressures, which was critical in my application. In addition, the fact that the design does not have an anode shield or clamp greatly reduces contamination in my process and enables me to run longer without venting my chamber for cleaning. This new magnetron design is a significant upgrade to Kurt Lesker's sputtering systems and will be considered in all of my future application requirements. – Learn more about the TORUS® Mag Keeper™ UHV Compatible Circular Magnetron Sputtering Sources. ”
