Praxair Electronics offers a complete portfolio of semiconductor
process gases from state-of-the-art facilities in North America,
Europe and Asia. Our products satisfy exacting standards for
quality control, reliability and high-purity to meet the stringent
needs of the silicon, compound semiconductor, LCD and LED markets.
We understand the requirements for stringent
purity and uniformity necessary for consistent, high-volume device
fabrication. Trace impurities at the parts-per-billion, and
even parts-per-trillion levels, are measured and controlled.
Our offerings include silicon precursors, dopants, etchants,
reactants, mixtures and inerts–available in every major
cylinder and valve type. Praxair Electronics has gas manufacturing
and processing facilities worldwide. Our Kingman, Arizona facility,
in operation since 1991, manufactures arsine and phosphine. It
also houses transfill systems for silane, chlorosilanes, ammonia
and various halocarbons among other process gases. Our Oevel,
Belgium facility began operations in 1974, and offers a complete
portfolio of gases. In 2003, state-of-the-art automated equipment
and advanced technology processes were added to drain, prepare,
fill and test cylinders to meet higher standards required for
next-generation devices. Praxair’s facility in Giheung,
Korea is home to the largest UHP pipeline complex in the world.
In addition, our electronics specialty gas plant provides local
and regional support to our customers. In Taiwan, Praxair provides
local transfill of silane and a full semiconductor process gas
portfolio from Hsin Chu.
