Jason Campbell (Fed)

Dr. Campbell is an electrical engineer in the Nanoscale Processes and Measurements Group in the Nanoscale Device Characterization Division of the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST). He received his B.S. and Ph.D. in Engineering Science from the Pennsylvania State University, University Park, PA in 2001 and 2007, respectively. His research was focused on electrically-detected magnetic resonance measurements to identify the atomic scale defects involved in one of the most important advanced CMOS reliability problems (the negative bias temperature instability). In 2007, he was awarded a National Research Council (NRC) post-doctoral fellowship which he spent in the Semiconductor Electronics Division at the National Institute of Standards and Technology (NIST) where he is currently employed as a staff member. He has contributed to more than 50 refereed papers and conference presentations at national and international conferences and has been involved in the technical and managerial committees of both the IEEE IIRW and IEEE IRPS conferences. His research interests involve the fundamentals of the negative bias temperature instability, random telegraph noise in highly scaled devices, galvanomagnetic transport effects, and alternative magnetic resonance measurements.

Non-Resonant Electron Spin Resonant Probe And Associated Hardware

NIST Inventors
Jason Campbell , Jason Ryan , Kin (Charles) Cheung , Robert Gougelet and Pragya Shrestha
This invention details a non-resonant probe designed to measure changes in the density of broken bonds (unpaired electrons) in materials exposed to ionizing radiation. The probe functions to excite and detect electron spin resonance transitions in these materials. Accumulated radiation dose can then

Phase Shift Detector Process for Making and Use of Same

NIST Inventors
Kin (Charles) Cheung , Jason Ryan and Jason Campbell
The detector senses very small phase shifts in a highly balanced microwave bridge. An electric field optimized microwave probe, in close proximity to a sample, serves to perturb the degree of bridge balance due to a .change in effective dielectric constant of the sample. The major innovation
