Abstract

An inductor chip device for mounting on multichip-module, direct-chip-attach or surface-mount assemblies comprises a dielectric substrate (12), a spiral metallisation structure (14) defined on one major surface of the substrate, and a plurality of solder bumps (18, 19) defined on the other major surface of the substrate, the spiral structure being electrically connected to the plurality of solder bumps by means of metal-filled vias. Single or multilayer inductors may be defined, the latter providing higher inductance values in the same chip area. The multilayer inductors are constructed using a multilayer metal-polyimide or similar dielectric structure. The chip inductor provides a very small, accurate, discrete device with high inductance, high Q-factor and high self-resonant frequency. <IMAGE>
