  • Patent number: 6080526
    Abstract: A process for the preparation of substrates used in the manufacture of integrated circuits wherein spin-on low dielectric constant (low-k) polymer films are applied on semiconductor substrates. A non-etchback processing of spin-on low-k polymer films, without losing the low dielectric constant feature of the film, especially in between metal lines, is achieved utilizing electron beam radiation. A polymeric dielectric film is applied and dried onto a substrate and exposed to electron beam radiation under conditions sufficient to partially cure the dielectric layer. The exposing forms a relatively more hardened topmost portion of the dielectric layer and a relatively less hardened underlying portion of the dielectric layer.
