Abstract:
A process for improving the fabrication of etched semiconductor devices, comprising the steps of:a) depositing a first layer of an adhesion promoter over a substrate and patterning the adhesion promoter to form a mesa of adhesion promoter over the substrate; b) depositing a hydrocarbon planarization material over the substrate and over the mesa formed on the substrate; c) defining the hydrocarbon planarization material so that at least a portion of a first surface of the mesa is exposed; d) depositing a second layer of adhesion promoter over the hydrocarbon planarization material; e) defining a first mask and etching back the second layer of adhesion promoter so as to form an adhesion promoter pad and an adhesion promoter neck over a portion of the hydrocarbon planarization material; and f) depositing a first metal over the adhesion promoter pad and over the adhesion promoter neck.
