Ultra High Purity Phosphine Gas

High-purity phosphine gas is commonly used in the electronics and TFT-display industries as an n-type dopant source. This includes making transistors on silicon semiconductor for processor chips and memory chips. It is also used in growing epitaxy layers for the production of III-V compound semiconductor devices such as LEDs and laser diodes.

Solvay supplies high-purity phosphine gas to the semiconductor industry under the brands CYPURE® (99.9996% purity) and CYPURE® ULTRA (99.9999% purity).
