prof. M. Yamaguchi: Soft Magnetic Thin Film Applications at Radio Frequencies
14.09.2012 13:00
This lecture begins with a review of new soft magnetic thin film applications at radio frequencies for future system-in-package (SiP) and system-on-chip (SoC) technologies. Proposed in late 1970s, these thin film soft magnet applications have evolved from inductive read/write recording head technology to the frontiers of GHz frequency device applications. Discussions covered in this lecture include: (1) Development of international cross measurements of RF permeameters [2] to evaluate RF permeability and related FMR profiles of magnetic films; (2) small signal high permeable low loss applications to CMOS integrated inductors [3]; (3) small signal lossy application to CMOS integrated electromagnetic noise suppressor [4]; (4) small to medium signal applications as new metal/ferromagnetic multi-stack ?conductors? to suppress skin effect utilizing negative permeability beyond the FMR frequency [?r?
