WebLe CHF 3 est utilisé dans l'industrie du semi-conducteur, notamment pour la gravure ionique réactive (RIE) du dioxyde de silicium et du nitrure de silicium. Connu sous le nom de R-23 ou HFC-23, c'est un réfrigérant, remplaçant parfois le chlorotrifluorométhane (CFC-13). C'est un sous-produit de la synthèse de ce dernier 8 . WebThe free ion yields at zero applied electric field strength in the liquid fluoromethanes are Gfi0 in CH3F, 1.9 in CH2F2 and 1.1 in CHF3, all at 183 °K, and 0.07 in CF4 at 143 °K. Giga-fren Selon ce mode de réalisation, un niveau élevé d'anisotropie verticale est obtenu par un rapport de trois gaz ; à savoir les gaz CHF3 , Cl2 et O2 avec RF et ICP.
