Company to Present Update on HVPE System Development

MERRIMACK, N.H., Oct. 14, 2013 (GLOBE NEWSWIRE) -- GT Advanced Technologies
(Nasdaq:GTAT) is participating in the LED Forum Taipei 2013 event being held
in Taipei, Taiwan October 16-17, 2013. GT's Chief Technology Officer, Dr.
Raghavan, will discuss the key elements of HVPE GaN system and the expected
advantages the system will provide for manufacturers.

Last May, GT announced that it would develop, manufacture and commercialize a
HVPE system incorporating Soitec Phoenix Labs' (a subsidiary of Soitec) unique
and proprietary HVPE technology including its novel and advanced source
delivery system that is expected to lower the costs of precursors delivered to
the HVPE reactor. The HVPE system will enable the production of low cost GaN
templates on sapphire at scale. GT estimates that its HVPE system could lower
precursor costs by greater than 80 percent while improving the throughput of
expensive MOCVD tools and lowering CAPEX costs by up to 25 percent. The
expected target date for the commercial availability of the HVPE system is the
second half of 2014.
