Air Products expanding WF6 capacity

January 19, 2007 – Air Products says it will expand capacity for tungsten hexafluoride (WF6) at its electronic specialty material manufacturing facility in Hometown, PA, resulting in a 60% boost to the company’s WF6 production during 1H07.

The new production unit will be an exact duplicate of the company’s existing production capabilities, including all-nickel construction with automated process systems and a proprietary distillation process to remove impurities. The company also houses a trace metals lab at its Hometown site.

“We forecast solid growth for WF6 and feel that the timing is right to add more capacity, and further extend our leadership in fluorine chemistry,” said Corning Painter, VP of electronics for Air Products, in a statement.

Tungsten is used to construct vias connecting layers of aluminum separated by a dielectric layer.
