SEMETROL was started in 2005 to develop and market advanced semiconductor characterization and analysis systems. The characterization methods include deep level transient spectroscopy (DLTS), current-voltage-temperature (IVT), capacitance-voltage profiling (CV), thermal admittance spectroscopy (TAS), and other related methods.
Advanced data collection and analysis methods are used. This eases thorough characterization of semiconductor materials, and assists in improving material and device quality.
Each system has been carefully designed to produce accurate results very efficiently. New users of sophisticated characterization equipment face a daunting challenge. You not only need to understand the physics behind the measurements, but also the operational challenges of obtaining valid data. Even more so, you need to conduct valid analysis. Semetrol’s System facilitates each of these steps.

Daniel Johnstone formed Semetrol after several years experience in characterization and analysis with a broad range of semiconductor materials. Professional preparation includes a PhD in Engineering Physics, Master’s Degree in Electrical Engineering, and Bachelor’s Degrees in Electrical Engineering and in Ceramic Engineering.
Interest and experience in semiconductor properties was stimulated and formed while working in two of the Air Force research laboratories, and as a program manager for basic research in optoelectronic materials at the Air Force Office of Scientific Research. At AFOSR he started several multi-million-dollar research programs. These included new basic research initiatives in chalcopyrite non-linear optical materials, phonons in device structures, and next-generation epitaxial crystal growth. Working at Virginia Commonwealth University as an Associate Professor provided day-to-day interface with graduate students and post-docs, maintaining focus on grants and contracts progress.
