Abstract:
A method of forming a semiconductor device comprising:forming on a substrate a silicon based carbon doped oxide dielectric layer; removing excess material from the silicon based carbon doped oxide dielectric layer using a chemical mechanical polishing process; transferring the substrate with the silicon based carbon doped oxide dielectric layer to a cleaning unit; exposing the surface of the silicon based carbon doped oxide dielectric layer, while in the cleaning unit, to a solution for less than about 80 seconds at a temperature of between about 20Â° C. and about 70Â° C., the solution comprising a hydrophilic component and a corrosion inhibitor, the hydrophilic component comprising between about 0.01% and about 50% of the solution by weight and the corrosion inhibitor being included in the solution at a concentration of between about 0.001M and about 0.05M; and then coupling the hydrophilic component to the surface of the silicon based carbon doped oxide dielectric layer, wherein the hydrophilic component is selected from the group consisting of N-[(3-Trimethoxysilyl)propyl]ethylenediamine triacetic acid and trimethoxysilylpropyldiethylenetriamine, and wherein the corrosion inhibitor is selected from the group consisting of benzotriazole, cetyltrimethylammonium hydroxide, and a cetyltrimethylammonium halide.
