Abstract: A method is provided to isolated conductive pads on top of a multi-layer polymer device structure. The method utilizes laser radiation to ablate conductive material and create a non-conductive path, electrically isolating the conductive pads. The process is self-limiting and incorporates at least one layer within the stack that absorbs the radiation at the required wavelength. The prevention of radiation degradation of the underlying layers is achieved, as absorption of radiation occurs primarily on the surface of the structure, but not in any of the radiation sensitive underlying layers of the electronic device. The method preferably uses low energy infrared radiation which has been shown to produce little debris and no device degradation.
