Job description

Multibeam Corporation is a leading high productivity electron-beam technology innovator in waferfabequipment. Our technology will revolutionize the industry with maskless, full-wafer patterning capabilities. Our multi-column direct write system pushes what is possibleby enabling rapid prototyping to volume productionwith maskless lithography flexibility.

At the heart of Multibeam technology is an array of miniature e-beam columns that provide a maskless and high-throughput platform for writing nanoscale IC patterns seamlessly across full wafers. This solves key limitations widely recognized with e-beam lithography, transforming it from a mere R&D curiosity to an incredible fab tool for production. With MEBL systems, device makers can save on lithography costs, safeguard the IC supply chain, and revolutionize microelectronics manufacturing.

We believe the key to our successareour people. Our best employees love what they do and bring unique backgrounds to our fast-paced, highly collaborative environment. We are managed by some of the brightest in Silicon Valley, including Dr. David K. Lam, founder and prior CEO of Lam Research. The ideal candidate is independent, flexible, and enjoys working in a fast-paced and creative technical environment.
