Institute of High Pressure Physics

The Institute of High Pressure Physics Polish Academy of Sciences (IHPP PAS) is currently the leaseholder  of the Ammono Company, which manufactures gallium nitride (GaN) wafers with the ammonothermal method. The lease has been conducted in the best interest of nitride semiconductor science and technology.

The Ammono Company has been in receivership since 2015. The tenancy, founded by the Polish Ministry of Science and Higher Education, will enable a close cooperation between the groups involved in ammonothermal and Hydride Vapor Phase Epitaxy (HVPE) crystallization of GaN. The latter is performed at IHPP PAS and as a result of common projects a possible synergy of these two methods has been revealed. Ammono owns a pilot line of ammonothermal GaN wafers and IHPP PAS is building a pilot line for HVPE GaN substrates.

The lease and collaboration will lead to further development of both methods and, in the future, to merging of the two technologies and mass production of high-quality GaN wafers required for electronic and optoelectronic devices based on GaN. The tenancy will also enable knowledge transfer among researchers involved in GaN crystallization for more than two decades.
