Abstract: Disclosed is a method for manufacturing a magnetic field detecting element, capable of simplifying the manufacturing process and providing a thin-type magnetic field detecting element. The disclosed method for manufacturing a magnetic field detecting element according to the present invention, is characterized in forming a seed film on the semiconductor substrate, then partially removing the seed film using a predetermined pattern in advance, for insulation of a plurality of coil lines that would be formed on the seed film, forming a soft magnetic core, and cutting off edges of the semiconductor substrate so that a plurality of the coil lines may be insulated.

Abstract: A method for fabricating a high temperature superconducting step-edge Josephson junction includes the steps of: (i) preparing a step-edge on an SrTiO3 (STO) substrate; (ii) depositing a YBa2Cu3O7−x (YBCO) thin film on the step-edge substrate obtained; and (iii) forming a micro-bridge pattern on the, deposited metal thin film by photolithography and ion milling and then performing a heat treatment. This makes it possible to fabricate a step edge having a linear portion inclined at a large angle with good reproducibility during the ion-milling step. Furthermore, the two-stepped process of post heat treatment is carried out after the metal electrode of the junction is formed so that the high temperature superconducting step-edge junction can have its own characteristics enhanced.
