摘要:
A method of manufacturing a semiconductor device comprising forming a protective film on a surface of a lower-layer interconnection, and forming a multilayer-structured film by stacking a first porous film, a first non-porous film, a second porous film, and a second non-porous film on a surface of the protective film in this order, and forming a via hole and an interconnect trench. After a resist mask is removed, protective film exposed at a bottom of the via hole is removed. An upper-layer interconnection of dual damascene structure is formed by embedding an interconnect material in the via hole and the interconnect trench.The first non-porous film includes a first layer has a high etching selectivity ratio relative to the protective film, and a second layer has a high etching selectivity ratio relative to the resist mask and the second porous film.
摘要:
A method of forming an insulating film which includes the steps of: dissolving in a solvent a first and second polymer which each comprise methylpolysiloxane as the main component and one of which has a weight average molecular weight at least 10 times that of the other to thereby prepare a chemical solution; applying the chemical solution to a semiconductor substrate to form a coating film; and heat-treating the coating film to thereby form an organosilicon oxide film. The weight-average molecular weight of the first polymer is preferably at least 100 times that of the second polymer. Thus, an insulating organosilicon oxide film having a low dielectric constant and high cracking resistance is formed from a coating fluid.
