ABSTRACT:
In a method of forming an electrical circuit assembly, a substrate is provided including a plurality of first segments that form an electrical circuit. The first segments have surfaces that rise above surfaces of other segments that form the electrical circuit. All of the segments are deposited on the substrate via one or more shadow mask vapor deposition processes in a vacuum. A photoresist caused to cover all of the segments is hardened and then abraded until surfaces of the first segments are exposed, but surfaces of the other segments are not exposed, and a surface of the abraded photoresist is at the same level as the exposed surfaces of the first segments. Second segments can be deposited on the exposed surfaces of the first segments via a shadow mask vapor deposition process in a vacuum to a level above the top surface of the abraded photoresist.
