Latest Patents

Among his notable inventions, Armstrong designed an Environmental Scanning Electron Microscope (ESEM). This advanced ESEM distinguishes itself by achieving image resolution that rivals that of conventional scanning electron microscopes (SEMs). Key features include a biased ring electrode that efficiently detects secondary electron signals from the specimen surface, and a biased pressure limiting aperture electron detector that mitigates noise from backscattered electrons. The ESEM also optimizes the signal amplification of secondary electrons, ensuring minimal noise interference while providing a suitable bandwidth for imaging. Users benefit from an optical window system that allows for a seamless switch between electron imaging and optical light views of the sample, with a field of view expanded to 7 to 10 mm. Furthermore, Armstrong's design enhances the field of view through strategic arrangements of scanning coils and magnetic focusing lenses.

Another of Armstrong's significant patents is an Adhesion Cooling system for an ion implantation system, specifically tailored for silicon wafers. This innovative design features a rotatably mounted wafer pedestal equipped with multiple elastomer substrates to efficiently transfer heat generated from ion collisions away from the wafers. The substrates include elongated depressions that assist in wafer loading and unloading, preventing pressure buildup during the lift-off process, thereby improving operational efficiency.
