The Polish Academy of Sciences’ Institute of High Pressure Physics (IHPP PAS) has announced that it has become the ‘leaseholder’ of the Ammono Company. Ammona, a maker of s GaN wafers with the ammonothermal method, has been in receivership since 2015.
The tenancy, established by the Polish Ministry of Science and Higher Education, will enable a close cooperation between the groups involved in ammonothermal and HVPE crystallisation 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 crystallisation for more than two decades.Ammono offers ammononothermal and HVPE single crystalline GaN wafers of different electrical properties and diameter up to 2-inch. It also provides machining service of GaN, including surface preparation (mechanical, chemomechanical polishing and cleaning) and slicing/dicing of crystals and wafers.
