MICRO-COMPONENT COMPRISING A PLANAR INDUCTANCE AND METHOD FOR PRODUCTION OF SUCH A MICRO-COMPONENT

摘要

A micro-component incorporating a planar inductance, arranged above the final apparent Metallization layer (2) arranged within the substrate (1), has a metallic planar coil and two layers of high magnetic permeability arranged on both sides of the coil. Each layer of high magnetic permeability is formed of a stack (23, 54) of successive elementary layers (17, 19, 21, 52) of a material with high magnetic permeability and elementary layers (16, 18, 20, 22, 53) which are electrically insulating. An Independent claim is also included for a method for the fabrication of such a micro-electronic component incorporating a planar inductance.
