Monitoring and control of chemical composition of InGaN layers during MOCVD

By |2021-07-09T15:16:16-05:00March 14th, 2015|

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 the central wavelength over the [...]

Advanced broad spectrum endpoint detection technology for stripping and etching systems

By |2021-07-09T15:15:20-05:00March 14th, 2015|

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 corners the market. AccuStrata is [...]

Wire handheld Fluorometer and Rapid Awareness for Bacteria detection

By |2021-07-09T16:15:09-05:00March 14th, 2015|

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 achieve a wide reaching foodborne [...]
