Abstract:
1. An electronic device comprising: a conductive feature; a first ultraviolet (UV) blocking layer overlying the conductive feature, the first UV blocking layer being within 90 nm of the conductive feature; a first insulating layer overlying the first UV blocking layer, wherein the first insulating layer is at least 4 times thicker than the first UV blocking layer, a via opening extending through the first insulating layer and the first UV blocking layer; a second UV blocking layer overlying the first insulating layer; and a second insulating layer overlying the second UV blocking layer, an interconnect trench defined in the second UV blocking layer and the second insulating layer; and a conductive structure extending into the via opening within the first insulating layer and the first UV blocking layer and along the interconnect trench defined in the second UV blocking layer and the second insulating layer, wherein the conductive structure is electrically connected to the conductive feature.
