Abstract:
1. An ultra low k dielectric film reagent, selected from the group consisting of: (a) bicyclo[2.2.1]-hepta-2,5-diene having a water content ≦10 ppm, and a temperature below 0° C.; (b) bicyclo[2.2.1]-hepta-2,5-diene having a water content ≦10 ppm, protectively isolated from water and oxygen contamination by at least one gas selected from the group consisting of helium, argon, nitrogen and krypton; (c) bicyclo[2.2.1]-hepta-2,5-diene having a water content ≦10 ppm, in mixture with a radical inhibitor selected from the group consisting of BHT, BHA and ethyl vanillin; (d) diethoxymethylsilane having a water content ≦10 ppm, being azeotropically distilled with a distillation solvent selected from the group consisting of benzene and isopropyl ether; (e) diethoxymethylsilane having a water content ≦10 ppm, and a chlorine content ≦10 ppm, based on weight of the diethoxymethylsilane; (f) diethoxymethylsilane having a water content ≦10 ppm, in mixture with a drying agent selected from the group consisting of CaH (g) diethoxymethylsilane having a water content ≦10 ppm, in mixture with a chlorine scavenging agent selected from the group consisting of ethanol/sodium ethoxide, ethanol/organic amines, silver-nitrate-zeolite, silver-nitrate-silica, ion-exchange resin, and activated alumina; (h) diethoxymethylsilane having a water content ≦10 ppm, in mixture with a radical inhibitor selected from the group consisting of BHT, BHA and ethyl vanillin; (i) diethoxymethylsilane having a water content ≦10 ppm, in mixture with an end capping agent comprising Me (j) combinations of two or more of the foregoing.
