Aixtron AG, an Aachen, Germany-based supplier of compound semiconductor equipment, announced it will install a GaN MOCVD mass production system at Samsung Electro-Mechanics Co. Ltd., in Suwon-City, South Korea. The AIX 2600G3 HT reactor will be used for the development and production of blue and white light-emitting diode devices. MOCVD, or metal-organic chemical vapor deposition, is a technique to grow thin film III-V compound semiconductors such as gallium nitride (GaN)-, gallium arsenide- and indium phosphide-based materials. These materials are used in devices such as light-emitting diodes, solid-state lasers, photovoltaics, infrared detectors and high-power/high frequency transitors.. . .Tokki Corp., a supplier of manufacturing equipment to the organic light-emitting diode (OLED) industry, Hitachi High-Technologies Corp., a Japanese trading company, and Universal Display Corp., a developer of OLED technologies for flat panel displays and other opto-electronic applications, announced they have installed a new OLED deposition system at Universal Display's facility in Ewing, N.J. The companies said the multi-chamber, semi-automatic EL VESS020 system -- the first of its kind to be installed in the US -- is designed to deposit a variety of organic and metallic films using vacuum sublimation and evaporative techniques.. . . Spire Corp. has been awarded a $100,000 Phase I Small Business Innovation Research grant from the Centers for Disease Control and Prevention (CDC) to develop a more rapid method for the detection of plague organisms. Spire will initially design, construct and evaluate a prototype of a highly sensitive, portable optical instrument that would use fluorophores to identify the presence of plague pathogens in the body. Successful demonstration of the prototype's feasibility could lead to a Phase II program with funding of up to $1 million.

Glossary
light-emitting diode
An LED, or light emitting diode, is a semiconductor device that emits light when an electric current passes through it. LEDs are widely used in various applications due to their energy efficiency, compact size, and long operational life. The technology behind LEDs is based on the phenomenon of electroluminescence. Key characteristics and features of LEDs include: Electroluminescence: The process by which LEDs emit light is called electroluminescence. It involves the recombination of...
