Abstract :
Integrated magnetic components compatible with organic (low-temperature) electronic packaging for miniature DC/DC converters and other power supply applications are investigated. Two inductor types have been fabricated incorporating a polymer/ferrite composite core, deposited and patterned at low temperature. For the fabricated inductors, inductances in the 0.5-1.5 μH range and Q-factors of the order of 17 are achieved. In all cases, the incorporation of the polymer filled ferrite improved the characteristics of the integrated inductors
