About

J. E. McMurtry has made foundational contributions to semiconductor manufacturing and nanoscale metrology, particularly through the development of advanced inspection systems for lithographic masks. His key research areas include electron-beam inspection, defect detection, and x-ray mask production—critical technologies for ensuring the integrity of integrated circuits at ever-shrinking dimensions. McMurtry is best known as the lead inventor of SEMSpec, a scanning electron-beam inspection system that revolutionized die-to-die inspections of conductive x-ray masks, wafer prints, and stencil masks. His seminal 1991 paper on this system, which has garnered 14 citations, demonstrated a remarkable inspection sensitivity capable of detecting 97% of 50-nanometer defects at a throughput of 27 minutes per square centimeter—a significant achievement for its time. This work directly addressed the growing need for high-resolution, production-compatible defect detection in advanced lithography. McMurtry’s innovations have had lasting impact on the semiconductor industry, enabling more reliable mask production and paving the way for subsequent generations of electron-beam inspection tools. His research remains a cornerstone for engineers and scientists working on nanoscale fabrication and quality control.
