Abstract:
1. A method for forming a fluorinated film on a surface, the method comprising: (a) depositing a fluorinated film comprising active sites on the surface by exposing the surface to a RF plasma in a chamber, the RF plasma comprising fluorine-containing molecular fragments generated from a gas comprising fluorinated hydrocarbon precursor molecules; (b) pumping down the chamber to remove the gas comprising fluorinated hydrocarbon precursor molecules; and (c) quenching the active sites by exposing the fluorinated film to a gas comprising fluorinated hydrocarbon quenching molecules in-situ, in the absence of plasma, wherein the fluorinated film comprises no more than about 3 atomic percent oxygen, and further wherein the pumping step occurs prior to the quenching step.
