Method for the production of a structured composite with high-temperature superconductor material

A method for producing a layer having a structure formed of a first material having at least one recess, said structured layer being deposited on a substructure formed of at least one second material, one of said first and second materials including a metal oxide superconductor material with a high transition temperature which is sensitive to solvents containing acids, said method comprising the steps of:

• forming a first composite by applying a varnish layer to the substructure, the varnish layer is soluble in a first solvent that does not attack the substructure and has a structure corresponding to the structure of the structured layer of the first material to be produced;
• cold depositing, on the first composite, an auxiliary layer of a third material that is soluble in a second solvent which does not attack the first and second materials and which cannot be attacked by the first solvent and does not enter into any reaction with the first and second materials at an elevated deposition temperature at which the first material is deposited, and further is itself substantially unreactive at the elevated deposition temperature;
• forming a second composite from the first composite by removing the varnish layer along with a part of the auxiliary layer resting thereon using the first solvent;
• applying the layer of the first material to said second composite at said elevated deposition temperature that is approximately between 150.degree. C. and 1000.degree. C. in an atmosphere containing oxygen;
• and
• removing with the second solvent a remaining part of the auxiliary layer remaining in the area of the at least one recess along with the portion of the layer of the first material resting thereon.
