Etching Selectivity at Andrew Farr blog

Etching Selectivity. Plasma etching is thus primarily a chemical etching process and consequently produces an isotropic etching profile with. • etch profiles can be very anisotopic, and selectivity can be good • many different mechanisms proposed for this synergistic etching between physical and chemical components. Etch selectivity between two materials is defined as the ratio between their etching rates at identical plasma conditions. • what is dry etching? Using the chemistry of the etch to remove material into a solution (liquid or. • development of dry etching • plasma. Etching can be characterized by how much of the process is: The etch rate of si depends on the aspect ratio due to the transport effect of neutrals, which decreases etch rate as depth increases [6],. The increase of cl 2 percent in clf 3 /cl 2 gas mixture. In this study, isotropic dry etching characteristics of sin x and sio 2 using clf 3 /cl 2 remote plasmas have been investigated.
