Filed: 1991-04-25
Abstract: PURPOSE:To flatten the surface and facilitate multilayer wiring and improve reliability by using a superconductive film as wiring material, and making its one part normally conductive. CONSTITUTION:A superconductor forming film 1 is made by sputtering the target of such composition that Bi:Sr:Ca:Cu:O=1.4:1.0:1.0:1.5 at 2.7Pa of gas pressure in Ar/20%O2 atmosphere. This is made into a superconductor, being annealed in O2 atmosphere at 800-900 deg.C. The section excluding 1' is made normally conductive by applying a focused beam partially hereon and annealing it. By this work, it follows that a current flows only through the section 1' when cooled to Tc or less. After formation of a pattern, an interlayer insulating film 2 is formed, and further a superconductive forming film 3' is formed thereon, and its one part 3 is made normally conductive. Since etching pattern is formed without being etched, the flattening of the surface of the element, the multilayer wiring, and the simplification and speedup of process become possible.
