ANTI-FUSE AND FUSE STRUCTURES FOR IMPROVING THE FUNCTIONALITY OF QUBIT CIRCUITS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240113015 titled 'ANTI-FUSE AND FUSE STRUCTURES FOR IMPROVING THE FUNCTIONALITY OF QUBIT CIRCUITS

Simplified Explanation

The method described in the abstract involves constructing a superconducting switch by depositing a sacrificial layer on a substrate, patterning the sacrificial layer to leave it only at a specific portion of the substrate, depositing a superconducting metal layer on top of the substrate and sacrificial layer, patterning the superconducting metal layer to form a superconducting metal line, and etching the sacrificial layer from under the metal line to release it from the substrate.

Original Abstract Submitted

a method of constructing a superconducting switch includes depositing a thin sacrificial layer on top of a substrate. the sacrificial layer is patterned to remove portions of the sacrificial layer except at a first portion of the substrate. a superconducting metal layer is patterned on top of the substrate and on top of the sacrificial layer. the superconducting metal layer is patterned to form a superconducting metal line over the sacrificial layer. the patterned sacrificial layer is etched from under the superconducting metal line to release the metal line from the substrate.
