Building and improving advanced device fabrication processes
Semiconductor Process Development
In industry, I have worked across complex GaN-based microLED fabrication flows involving lithography, dry etching, dielectric passivation, metallization, thin-film deposition, thermal processing, metrology, and device integration.
My work has included process optimization, troubleshooting yield-limiting failure modes, evaluating alternative process approaches, and coordinating fabrication across multiple cleanroom facilities.
Superconducting & Quantum Devices
During my PhD in condensed matter physics, I developed and characterized superconducting thin films and nanoscale devices for quantum-transport experiments.
This work combined epitaxial thin-film growth, lithography, nanofabrication, structural characterization, and low-temperature electrical measurements, giving me a strong foundation at the intersection of materials science, device physics, and fabrication.
