On the relationship between SiF4 plasma species and sample properties in ultra low-k etching processes

AIP Advances, 2020
The temporal behavior of the molecular etching product SiF4 in fluorocarbon-based plasmas used for the dry etching of ultra low-k (ULK) materials has been brought into connection with the polymer deposition on the surface during plasma treatment within ...

Applications of fluorocarbon polymers in micromechanics and micromachining

Sensors and Actuators A: Physical, 1994
Several thin-film deposition and etching techniques of the polymer fluorocarbon are investigated and the resulting thin-film properties will be compared with those of commercially available bulk polytetrafluoroethylene. The most promising deposition technique is performed in a conventional reactive ion etcher using a carbonhydrotrifluoride (CHF3 ...

Speciation‐Controlled C–F Bond Functionalization Enabled by Zwitterionic Pnictinidenes

Angewandte Chemie, EarlyView.
Zwitterionic pnictinidenes turn C–F activation into C–X bond construction, enabling broad defluorinative functionalization of polyfluoro(hetero)arenes under mild conditions. Rather than following a metallomimetic Sb(I)/Sb(III) redox turnover, catalysis is redirected by ligand scrambling into a redox‐neutral manifold, revealing catalyst speciation as a ...

The Effect of Hydrogen Ion Bombardment on Fluorocarbon Polymers

, 1986
Polytetrafluoroethylene(PTFE), Polyvinylidene fluoride(PVFD), and Polymethylmethacrylate(PMMA) thin films have been bombarded with a H2 ion beam. The ion exposure time varied from 3 to 12 minutes corresponding to an ion dose of 1017H+/cm2 to 1018H+/cm2 ...
