Abstract:
A semiconductor device which comprises:(a) a layer of patterned conductors formed on a substrate and having an inorganic substrate encapsulation layer deposited conformally over said conductors and said substrate;(b) an organic-containing dielectric layer filling spaces between and covering said conductors, said organic-containing layer having a dielectric constant of less than 3.5, said organic-containing layer composed of a material containing 10% to 100% polymer by weight;(c) a cap layer comprised of inorganic material deposited over said organic-containing layer;(d) at least one via etched through said cap layer, said organic-containing layer; and said inorganic substrate encapsulation layer;(e) an inorganic passivating layer deposited on the sidewalls of said via where said via passes through said organic-containing dielectric; and(f) an electrical connection formed by filling said via with a conducting material, said electrical connection being connected to one of said patterned conductors, whereby connection can be made to a second level of patterned conductors deposited above the inorganic dielectric layer.
