Monitoring and control of chemical composition of InGaN layers during MOCVD
Metal-Organic Chemical Vapor Deposition (MOCVD) epitaxial processes are used to deposit the GaN, InGaN, AlGaN and other wide band-gap semiconductor thin films making up the buffer, quantum well, and cap layers of the next generation high-brightness LEDs (HB-LEDs) for Solid State Lighting (SSL). Non-uniformity of [...]
Advanced broad spectrum endpoint detection technology for stripping and etching systems
Advances in computational and spectroscopic technology have created great opportunity to produce an endpoint detection system that can accurately and reliably determine the endpoint of a process at relatively low cost. Availability of such a system is hindered by the saturation of the endpoint market by old, expensive technology that [...]
Wire handheld Fluorometer and Rapid Awareness for Bacteria detection
Despite significant advances in communal hygiene practices and food safety measures, foodborne illness is still a significant and deadly issue in the United States. The largest barriers to widespread foodborne illness detection are time to detection, speed of information dissemination and cost of testing. To [...]
