    摘要: An ultra low k dielectric film, including a silicon film containing porosity deriving from a porogen, as formed from a precursor silane and a porogen, wherein the precursor silane has a water content below 10 ppm, based on total weight of the precursor silane, and/or the porogen has a water content below 10 ppm, based on total weight of the porogen. In one implementation, the precursor silane is diethoxymethylsilane, and the porogen is bicyclo[2.2.1]-hepta-2,5-diene having a trace water content below 10 ppm, based on total weight of said bicyclo[2.2.1]-hepta-2,5-diene. These super-dry reagents are unexpectedly polymerization-resistant during their delivery and deposition in the formation of ultra low k films, and are advantageously employed to produce ultra low k films of superior character.
