ABSTRACT:
Several methods are disclosed for forming an air gap between crossing thin film conductors utilized to interconnect electronic components on a substrate. Each of the methods involves the use of photolithographic techniques to form overpassing conductors on a support material covering the overpassed conductors, followed by removal of the support material. Both deposition and plating techniques are described for forming the overpassing conductors.
