NEWS REVIEW Air Liquide acquires Voltaix
Air Liquide has signed an agreement to acquire Voltaix Inc., a U.S. based electronics materials company. The acquisition is expected to close later this summer, pending applicable regulatory approvals.
Founded in 1986, Voltaix is a manufacturer of materials used in the production of semiconductor devices and advanced solar cells, with expertise and global stewardship in silicon, germanium, and boron chemistries.
It operates manufacturing facilities in the U.S. in Branchburg (New Jersey), High Springs (Florida) and Portland (Pennsylvania) and in South Korea in Sejong-si (South Chungcheong Province).
The company employs 185 employees. Air Liquide, with its ALOHA product line, is a manufacturer of advanced precursors
for semiconductor manufacturing. Precursors are molecules with specific physical and chemical properties that are used for depositing critical layers during fabrication of microelectronic devices.
Air Liquide utilises a comprehensive process for designing, screening and industrialising advanced precursors in close cooperation with semiconductor industry leaders and process tool makers.
The acquisition of Voltaix complements the ALOHA offer and brings together synergies in molecule discovery and scale up, contributing to accelerate the introduction of a broader portfolio of new high-tech materials to semiconductor manufacturers and therefore enabling the increase in computing power and connectivity.

Schott And Tesat-Spacecom to soar into space
THE SCHOTT TECHNOLOGY GROUP and Tesat-Spacecom GmbH & Co. KG, have developed a hermetically sealed packaging solution that can be used in space.
The technology is supporting the European Space Agency (ESA) ’s satellite Proba-V to perform Earth observations since the beginning of May.
Schott says this housing contains a GaN power amplifier or MMIC chip (Monolithic Microwave Integrated Circuit) for the first time ever.
Schott and Tesat-Spacecom optimised material composition and geometry for an optimal heat sink for this packaging. What’s more, the packaging features hermetically sealed HTCC multilayer ceramics as high-frequency feed throughs that allow minimal insertion loss and reflection of the high frequency waves.
The communication system for the ESA mini satellite Proba-V that weighs about 140 kg is one cubic metre in size and contains a special microwave amplifier
on the basis of GaN that was installed for the first time ever there in an European Satellite.
The MMIC is used to transmit photos taken at a height of roughly 800 km in the X band at 8 GHz to monitor vegetation on our planet.
The semiconductor is capable of improving signal strengths and data transmission by five to ten times and will be used as a new high-performance material in communication systems.
