  • Carbon tetrafluoride | CF4 - PubChem

    The amount of adsorbed CF4 strongly depends on the pore size in nanotubes; at 1 bar the most efficient nanotubes for volumetric storage have size R = 0.68 nm. This size corresponds to the (10,10) armchair nanotubes produced nowadays in large quantities.

  • CF4 ANALYSIS - Indico

    Flow membrane 4 Flow membranes 2 and 3. MEMBRANE 1,2,3. Fifth step--- 24/08/2018 Redo other analysis with three membranes involved but with the flow evenly divided into M1,M2 and M3 (200, 200, 200). This because the first analysis were done with different flow between the three membranes (150, 300, 300). With an equal flow in M1, M2 and M3 we expected an higher concentration of CF4 because we increase flow in M1 which is the less efficient membrane but CF4

The wafer was vented to atmosphere immediately after the Al dry etch, after which the photoresist was removed using an oxygen plasma in the NGP80.. To mitigate such corrosion, the AlCl₃ should be removed as much as possible before the wafer is exposed to atmosphere.
