Kyma Technologies, a green 3P (People, Profits, Planet) high technology company based in the Research Triangle Area of North Carolina, has entered into the market of GaN crystal growth equipment with its hydride vapour phase epitaxy (HVPE) System.
 
HVPE is the dominant process used today for production of free-standing GaN substrates and recently has been used by Kyma and others to produce high quality GaN on sapphire templates and GaN on silicon templates. HVPE grown GaN templates have major advantages over free-standing GaN in terms of cost per unit area and diameter scalability.
 
The market for nitride semiconductor devices was around $9 billion in 2011 and is expected to surpass $60B over the long term, including $30B in visible lighting applications and $30B in power electonics applications.
