Method for fabrication of micro and nano constriction type structures on YBa2Cu3O7-x Superconducting thin films femtosecond Laser method (Nano structure).

This invention relates to a Femtosecond Laser-based method for the fabrication of micro- and nano-constriction type structures on a YBa2Cu3O7-x Superconducting thin film and to a new superconductor device. According to one aspect of the invention, there is a method of manufacturing micro- and nano-constriction type structures on a YBCO thin film, the method including:

ablating a predefined pattern onto the thin film by means of a femtosecond laser. In this specification, the definition of micro-constriction type structures relates to structures of which the constriction size is in microns and submicrons.

The sensors market is expanding, and it is regarded as one of the most promising areas in the semiconductor industry-sensor technology. It is an evolving discipline that holds the potential to significantly improve the performance, durability, maintenance, and applicability of many engineering projects.

Sensor technology adaptation is hampered by the scarcity of nanomaterials and the high cost of manufacturing. Cost will reduce when manufacturing processes improve to enable mass production. Nanosensor-based devices are sensitive and can detect analytes at the molecular level, which accelerates the adoption of the technology. With mass-scale manufacturing and deployment in various application areas, the technology is expected to mature quickly over the next 3-5 years.
