CVD Process Gases for Semiconductors

We have developed commercial tungsten hexafluoride which is used to mold metal wiring. We have also developed a commercial silicon gases for low-dielectric insulating layers that can accommodate the ongoing miniaturization and integration in semiconductors.

These are semiconductor specialty gases used in the formation of contact plugs and silicide.

Purity 99.9995% or more


  • CVD WSix, W Materials

SiH(CH3)3 (Trimethylsilane)

These are silicon gases for low dielectric constant interlayer insulating films that respond to advances in semiconductor device miniaturization and increasing integration.

Purity 99.9995% or more


  • SiC, SiOC, SiO2, SiN membrane materials
