ECCN 3C908
NSRSATFluorides, hydrides, chlorides, of silicon or germanium, containing any of the following .
What This ECCN Covers
ECCN 3C908 controls fluorides, hydrides, or chlorides of silicon or germanium containing the isotopic characteristics in the entry. These ultra-pure and isotopically tailored precursor chemistries support advanced semiconductors and are controlled for National Security, Regional Stability, and Anti-Terrorism reasons.
Who needs to check this?
Specialty-gas and electronic-materials suppliers exporting silicon/germanium precursor chemistries for advanced semiconductor fabrication.
Compliance tip
Control turns on the specific chemistry and isotopic content in the entry — standard precursor gases may fall outside. The RS reason ties into advanced-semiconductor policy; verify the Country Chart and treat advanced-node uses with added diligence.
Items Covered
- a.Silicon having an isotopic impurity less than 0.08% of silicon isotopes other than silicon-28 or silicon-30; or
- b.Germanium having an isotopic impurity less than 0.08% of germanium isotopes other than germanium-70, germanium-72, germanium-74, or germanium-76.
Control Reasons
Items controlled for national security reasons under multilateral export control regimes.
Items controlled for regional stability reasons.
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
