A process of forming an electronic device including forming a first ultraviolet (“UV”) blocking layer over a conductive feature, wherein the first UV blocking layer lies within 90 nm of the conductive structure; forming a first insulating layer over the first UV blocking layer; and patterning the first insulating layer and the first UV blocking layer to form a first opening extending to the conductive feature, wherein during the process, the first UV blocking layer is exposed to UV radiation.
