Hvpe reactor
Web15 mei 2009 · Date Announced: 15 May 2009. Oxford Instruments is pleased to announce the launch of CrystalFlex, a multi-wafer Hydride Vapour Phase Epitaxy (HVPE) reactor providing superb epitaxial growth control, and offering a cost effective route for the production of high quality, crack free epitaxial GaN, AlGaN and AlN single crystal materials. WebA reactor for growing or depositing semiconductor films or devices. The reactor may be designed for inline production of III-V materials grown by hydride vapor phase epitaxy (HVPE). The operating principles of the HVPE reactor can be used to provide a completely or partially inline reactor for many different materials. An exemplary design of the …
