Abstract:
A method of forming dielectric films, comprising the steps of:providing a substrate;forming a patterned layer of first conductor material on said substrate;forming a layer of first dielectric material on said patterned layer of first conductor material;forming a layer of second dielectric material on said substrate covering said layer of first dielectric material wherein said layer of second dielectric material has a dielectric constant of between about 1.0 and 3.0.;exposing said layer of second dielectric material to a nitrogen treatment by placing said substrate in a chamber having a nitrogen atmosphere at a temperature of between about 350.degree. C. and 450.degree. C. for between about 30 and 90 seconds;forming a layer of third dielectric on said layer of second dielectric after exposing said layer of second dielectric to said nitrogen treatment; andforming a patterned layer of second conductor material on said layer of third dielectric.
