Abstract
An integrated circuit arrangement includes at least one electrical conductor that, when a current flows through it, produces a magnetic field that acts on at least a further part of the circuit arrangement, wherein seen in cross section, the electrical conductor has at least one recess or depression, or a region of reduced conductivity on the side facing that part, in order to influence the magnetic field which can be produced.
Claims6
A method for producing an integrated circuit arrangement having one or more electrical conductors lying in a plane, which comprises:
- producing a further part in the form of a layer that can be influenced by a magnetic field, and subsequently carrying out the following steps:
- producing a material layer of nonconductive material corresponding to a position of an electrical conductor to be produced subsequently;
- reducing at least one of a thickness and a width of the material layer;
- applying an electrical conductor covering the material layer.
