Cost-effective Mass Production of SQUIDs MRI Technology

The invention relates to an automated process for fabricating nano and micro structures using high temperature superconducting quantum interference device (SQUIDS). This method overcomes the high cost and complexity in the manufacturing process of superconductors for a commercial scale or mass production. The method applies well-known Femptosecond Laser-based method to fabricate micro and nano – constriction type structures using an automated programme, providing better control, pre-programmed manufacturing of an array of superconductors. 

Today, reliable and stable thin-film Josephson circuits can be manufactured in large quantities. However, the production process of good quality SQUIDs is not simple. The main challenge is the technically demanding and reliability of the fabrication process of high temperature superconductors. Most well-established fabrication technology fails, particularly at nano-scale. Even the extremely sensitive SQUIDs present challenges when it comes to manufacturing
