Umicore Completes Construction Of New US Germanium Substrates Production Facility

Materials technology company Umicore has completed the construction of its new germanium substrates production facility in Quapaw, Oklahoma, USA, adjacent to the existing site.

The 40,000 square foot facility is now undergoing process start-up and qualification runs. The new substrate facility is located on the same campus as the Umicore germanium optics and high purity chemicals operation for the US market and will be integrated in the existing IS014001, 2004 system in the course of 2010. This allows for a completely integrated supply chain operation, emphasizing prompt internal recycling thereby minimizing inventory stocking requirements of the valuable germanium metal.

The production operation itself is modelled on the Olen facility in Belgium which has successfully supplied millions of substrates for space and terrestrial photovoltaic applications. The new facility in Quapaw embodies proven state-of-the-art equipment and an advanced product tracking system.

“With Quapaw in addition to Olen, our total installed annual production capacity stands at 1 million germanium wafers (4" eq). With our two Ge wafer plants in Europe and the USA, we’re now in an excellent position to meet market demand for the foreseeable future," says Carl Quaeyhaegens, General Manager of Umicore’s worldwide substrates business line.

Germanium wafers are a core component of triple junction (III-V) high-efficiency solar cells used on the vast majority of all satellites launched today. Triple junction (III-V) solar cells based on germanium wafers are also widely applied in terrestrial Concentrated PV systems (CPV), an emerging, highly promising, and ultimately lowest electricity cost technology of all PV technologies, for areas with high direct sunlight irradiation (DNI).
