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 [...]

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 [...]

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 [...]

AccuStrata is utilizing its expertise in thin film growth monitoring and optical system design to create a breakthrough AAS product, installable on a variety of PVD systems, to provide accurate and reliable deposition rate measurements for dynamic feedback control of the PVD systems. The system comprises two major parts – a reconfigurable hardware module located [...]
