A die has interconnect pads on an interconnect side near an interconnect edge and has at least a portion of the interconnect side covered by a conformal dielectric coating, in which an interconnect trace over the dielectric coating forms a high interface angle with the surface of the dielectric coating. Because the traces have a high interface angle, a tendency for the interconnect materials to bleed laterally is mitigated and contact or overlap of adjacent traces is avoided. The interconnect trace includes a curable electrically conductive interconnect material; that is, it includes a material that can be applied in a flowable form, and thereafter cured or allowed to cure to form the conductive traces. Also, a method includes, prior to forming the traces, subjecting the surface of the conformal dielectric coating with a CF4 plasma treatment.
