Acquisition of an Upgrading Kit for SiGeSn Epitaxy to Develop a Material Foundry for SiGeSn Based Optoelectronics
Abstract
Group-IV alloy SiGeSn materials have many unique optoelectronic properties for different device applications. The US Air Force made large investments in the last decade to develop theSiGeSn materials which lead to the significant research breakthrough evidenced by thedemonstration of GeSn based lasers and infrared detectors with world-record performance. Toensure continuous success of SiGeSn research, University of Arkansas (UA) proposes to teamwith an epitaxy service company Si Photonics Group, Inc. (SPG) to acquire a customer designedupgrading kit. The new upgrading kit could convert any existing ASM Epsilon 2000 plus reactorto be able to grow high quality SiGeSn materials. SPG will build the system and conduct testgrowth. After that, UA, SPG and a SiGe epitaxy foundry will form a partnership as a “virtualfoundry” to provide SiGeSn growth service. This partnership includes i) UA with ownership ofthe upgrading kit and extensive experiences of SiGeSn material property study and devicedevelopment; ii) SPG with expertise to grow SiGeSn materials using the ASM standard reactor;iii) the traditional SiGe foundry who owns many reactors to take this opportunity to add SiGeSnas a new material for their business development. The primary goal of the “virtual foundry” is tosupport the US government sponsored SiGeSn material development activities and to maintain US technical leadership. The foundry will also provide research community and industryaccessing high quality SiGeSn materials with affordable cost. The “virtual foundry” has greatadvantage in terms of material development cost. This will also enable many new researchdirections including: i) low cost infrared imaging; ii) room temperature THz emitter; iii) Highefficiency multi-junction space photovoltaics; and iv) new generation integrated microwavephotonics, all strongly related for future DoD research interests.
