This article relates generally to Superconducting Quantum Interference Devices (SQUIDs) and more particularly relates to a SQUID wherein the junctions involved are in a plane perpendicular to the plane of the substrate. Fig. 1 shows cross-sectional and plan views of the SQUID in device 1 which includes a substrate 2 having a pair of niobium or other superconducting material elements 3 disposed on the surface thereof. An insulating layer 4 of silicon dioxide or other suitable insulator is disposed on the surface of elements 3. Finally, a lead alloy counterelectrode 5 is shown disposed in the space between the insulator-covered elements 3 edge portions of which form a pair of junctions 6 with a portion of counterelectrode 5. The junctions thus formed are perpendicular to the plane of substrate 2.
