Abstract:
A process for forming a low dielectric constant fluorine and carbon-containing silicon oxide dielectric material comprising reacting with an oxidizing agent one or more silanes comprising one or more organofluoro silanes having the formula SiR1R2R3R4, wherein:(a) R1 is selected from the group consisting of H, a 3 to 5 carbon organo moiety, and an oxyorgano moiety; (b) R2 is an organofluoro moiety; and (c) R3 and R4 are independently selected from the group consisting of the same or different leaving group, the same or different organofluoro moiety, and the same or different ((L)Si(R5)(R6))n(R7); wherein n ranges from 1 to 5; L is O or (C(R8)2)m; m ranges from 1 to 4; each of the n R5's and n R6's is independently selected from the group consisting of the same or different leaving group and the same or different organofluoro moiety; R7 is selected from the group consisting of a leaving group and an organofluoro moiety; and each of the 2n*m or fewer R8's is selected from the group consisting of F and the same or different organofluoro moiety.
