How are ccif3 and cf4 similar
WebCF4 does not directly react with Si; rather it follows the path: CF4+e----CF3 (free radical) +F (free radical) +e Both the free radicals adsorb on Si. Now CF3 and F react to form CF4 which... WebThis is normally done at high pressure around 1 Torr and somewhat elevated temperature around 90 oC. The rate will strongly depend on the density of the material, so thermal oxide will etch very...
