    摘要: Low dielectric materials and films comprising same have been identified for improved performance when in integrated circuits as well as a method and a mixture for making same. In one embodiment of the invention, there is provided a mixture for forming a porous, low-k dielectric material comprising: at least one silica source having an at least one silicon atom and an organic group comprising carbon and hydrogen atoms attached thereto wherein at least one hydrogen atom within the organic group is removable upon exposure to an ionizing radiation source; and at least one porogen wherein the ratio of the weight of at least one porogen to the weight of the at least one porogen and SiO2 provided by the at least one silica source is 0.4 or greater. The mechanical and other properties of the porous, silica-based material are improved via exposure to the ionizing radiation source.
