Data carrier for identification systems
First Claim
1. Data carrier chip for identification systems comprising at least one integrated circuit including active semiconductor areas and uppermost conductive path structures and one coil arrangement connected to said integrated circuit, said coil arrangement being substantially located above the active semiconductor areas of the data carrier chip on sections of the uppermost conductive path structures, the improvement wherein the windings of said coil arrangement include a low-ohmic portion that is exclusively and monolithically provided on the data carrier chip itself with a cross sectional thickness in a direction parallel to the normal of the chip being greater than 5 μ
- m, said coil arrangement being aligned with said active semiconductor areas in said direction normal to said coil arrangement.
