Title:
MAGNETIC STRUCTURE, INDUCTANCE ELEMENT, METHOD FOR MANUFACTURING INDUCTANCE ELEMENT, SUBSTRATE HAVING BUILT-IN ELECTRODE, METHOD FOR MANUFACTURING SUBSTRATE HAVING BUILT-IN ELECTRODE, INTERPOSER, SHIELD SUBSTRATE, AND MODULE
Document Type and Number:
WIPO Patent Application WO/2016/035818
Kind Code:
A1
Abstract:
A magnetic structure (2) is provided with: a first magnetic layer (101); first slits (SL1) that divide the first magnetic layer (101) into a plurality of parts; a first insulating layer (12) that is disposed on the first slits (SL1) and the first magnetic layer (101); a second magnetic layer (102) that is disposed on the first insulating layer (12); and second slits (SL2) that divide the second magnetic layer (102) into a plurality of parts. The magnetic structure, which has reduced magnetic resistance and eddy-current loss, and an inductance element, which has the magnetic structure applied thereto, reduced alternating current resistance, and excellent high frequency characteristics, are provided.
