Abstract:
1. A method of manufacturing a semiconductor device, comprising: introducing an organosilicon precursor and at least one porogen into a chamber comprising a substrate and heating the substrate to a deposition temperature in a range of about 100° C. to less than about 245° C., thereby forming a porogen-containing dielectric layer on said substrate; and removing at least a portion of said at least one porogen from said porogen-containing dielectric layer to form a porous, low-k dielectric layer, wherein no oxidant is introduced into the chamber, wherein the chamber includes an electrode gap between an upper electrode and a lower electrode that is between 200 mm and 1000 mm, wherein said organosilicon precursor is represented by Chemical Formula 1 in which R 1 , R 2 , R 3 , R 4 , R 5 and R 6 each represent a hydrogen, a methyl group or an alkoxy group and n represents 1, 2, 3, 4 or 5, and wherein the ratio of bridging carbons to methyl groups in said porous, low-k dielectric layer is in a range of about 0.5:1 to about 3:1.
