A semiconductor device is fabricated with energy based process(es) that alter etch rates for dielectric layers within damascene processes. A first interconnect layer is formed over a semiconductor body. A first dielectric layer is formed over the first interconnect layer. An etch rate of the first dielectric layer is altered. A second dielectric layer is formed on the first dielectric layer. An etch rate of the second dielectric layer is then altered. A trench etch is performed to form a trench cavity within the second dielectric layer. A via etch is performed to form a via cavity within the first dielectric layer. The cavities are filled with conductive material and then planarized to remove excess fill material.

A method of manufacturing a semiconductor device is presented. In one aspect, the method comprises forming conductive and ferroelectric material layers on a semiconductor substrate. The material layers are patterned to form electrodes and a ferroelectric layer of a ferroelectric capacitor, wherein a conductive noble metal-containing polymer is generated on sidewalls of the ferroelectric capacitor. The method also comprises converting the conductive noble metal-containing polymer into a non-conducting metal oxide. Converting includes forming a water-soluble metal salt from the conductive noble metal-containing polymer and reacting the water-soluble metal salt with an acqueous acidic solution to form a metal hydroxide. Converting also includes oxidizing the metal hydroxide to form the non-conducting metal oxide.
