FemtoFab

FemtoFab™ introduces an automated femtosecond laser-based process for the fabrication of micro and nano-constriction structures on high temperature superconducting (HTS) thin films such as YBa₂Cu₃O₇-ₓ. The technique enables the precise and reproducible formation of superconducting nano- and micro-patterns used in quantum interference devices (SQUIDs) and other high-performance electronic systems. This method represents a significant advancement in superconductor manufacturing, overcoming the cost, complexity, and scalability barriers associated with traditional lithographic techniques.
By employing programmable, automated laser control, FemtoFab™ allows the rapid, low-cost, and high-fidelity fabrication of arrays of superconducting nano-structures suitable for research and commercial applications.
