Cambridge sf6 o2 joints pdf

Cyrogenic etching of silicon is envisaged to enable better control over plasma processing in microelectronics and to limit plasma induced damage for features beyond the 14 nm technology node. We here present results of plasma modelling for a SF6/O2/SiF4 plasma and of molecular dynamics (MD) simulations for predicting surface interactions, together with results of etch experiments for validation.

  • Expansion Joints – Engineering Guide

    The term “Fabric Expansion Joint” is a little misleading, in that it covers a wider range of products and materials than just “fabrics”. However, it is useful as a generic title for expansion joints which are non-metallic, and used in ducts at low pressures. Fabric expansion joints are used primarily to contain gaseous fluids.
