Utility Scale Light - Changing the Light Source Paradigm for Semiconductor Manufacturing
From lithography to metrology and inspection, light has been at the core of semiconductor manufacturing for decades. However, most light sources are typically constrained to some form of elemental emission line and tool-based form factor that limits power and tunability. xLight is building utility scale light sources that sit outside the fab and distribute light to a fleet of tools with substantially more power, tunability, and extensibility.
About the Speaker
Nicholas serves as Chief Executive Officer and Chief Technology Officer of xLight. Before assuming his roles, Nicholas led the development effort to build the world’s first useful quantum computer at PsiQuantum.
Nicholas spent 20 years in the Department of Energy National Lab system building and operating large scale, x-ray science facilities and instrumentation. Starting at Lawrence Berkeley National Lab, he developed novel instrumentation and large scale upgrades for the Advanced Light Source (ALS) and Berkeley Lab Laser Accelerator (BELLA) user facilities. He then moved to SLAC National Lab at Stanford where he was the Chief Engineer for the Linac Coherent Light Source (LCLS), a 3-mile-long x-ray free electron facility for ultrafast science.
