Abstract
A method for fabricating inductors and transformers on integrated circuits. A magnetic material is formed on the semiconductor substrate. The magnetic material comprises a suspension of magnetic material in an insulator. A metal film is formed that forms at least one coil around the magnetic material forming an inductor structure. Two adjacent coils can be linked with the magnetic material to form a transformer.
