Abstract
A method for using low dielectric SiOF in a process to manufacture semiconductor products, comprising the steps of obtaining a layer of SiOF, and depleting fluorine from a surface of the SiOF layer. In a preferred embodiment, the depleting step comprises the step of treating the surface of the layer of SiOF with a plasma containing ammonia. It is further preferred that the treated surface be passivated by a nitrite plasma. The invention also encompasses a semiconductor chip comprising an integrated circuit with at least a first and second layers, and with a dielective layer of SiOF disposed between the layers, wherein the SiOF dielectric layer includes a first region at one edge thereof which depleted of fluorine to a predetermined depth.
