Ogljikov tetrafluorid z visoko čistostjo

Ogljikov tetrafluorid z visoko čistostjo (večji ali enak 99 . 99%) je ključnega pomena za aplikacije, kjer bi lahko nečistoče v sledovih ogrozile uspešnost. Ta razred, ki nastane z delno destilacijo in kemičnim odlaganjem hlapov, ohranja stroge omejitve na vlagi (<5 ppm), oxygen (<10 ppm), and reactive fluorocarbons. The semiconductor industry consumes 70% of global high purity carbon tetrafluoride production, primarily for dielectric etching in 3D NAND and DRAM fabrication. Specialized gas delivery systems using electropolished stainless steel and ultra-high vacuum valves ensure purity from cylinder to tool. Recent advancements include real-time mass spectrometry for impurity tracking and cylinder coatings that reduce particulate generation.
