Webdepends on the F density in the plasma and the effects of ion bombardment. The process conditions for a high etch selectivity are a 0.3 to 0.5 CF4 flow ratio and a –600 V to –650 V DC bias voltage according to the process pressure in our experiment. Etching uniformity was improved with an increase in the CF4 flow ratio in the gas mixture, an WebAug 15, 2011 · Contour plot of Si etch rates (nm/min) as a function of source power and bias power.

WebCHF 3 is used in the semiconductor industry in plasma etching of silicon oxide and silicon nitride. Known as R-23 or HFC-23, it was also a useful refrigerant, sometimes as a replacement for chlorotrifluoromethane (CFC-13) and is a byproduct of its manufacture. When used as a fire suppressant, the fluoroform carries the DuPont trade name, FE-13. facial north park https://morrisonfineartgallery.com
