摘要： An improved method is presented for the deposition of dielectric films in the fabrication of integrated circuits (ICs), wherein a solution of polymers derived from cyclosilazanes is employed to deposit dielectric films on semiconductor substrates by the spin-on technique. These spin-on films planarize (smooth out) underlying substrate topography and therefore are especially advantageous in multilevel metallization processes where they allow a highly uniform and continuous deposition of a subsequent layer of metallization resulting in improved yield and reliability of ICs.
