ELECTROMAGNETIC NOISE SUPPRESSING BODY AND METHOD FOR SUPPRESSING ELECTROMAGNETIC NOISE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic noise suppressing body that can realize electromagnetic noise suppression without causing reflection even in the case of using a conductive magnetic thin film having an excellent magnetic loss characteristic for a very small electronic circuit placed inside a semiconductor device or the like and to provide an electromagnetic noise suppression method employing the body.;SOLUTION: This invention provides the conductive electromagnetic noise suppressing body made of a conductive soft magnetic thin film placed just on a signal transmission line such as a microstrip line and suppressing a conductive electromagnetic noise and the width of the conductive soft magnetic thin film is nearly equal to or narrower than the line width of the signal transmission line such as the microstrip line.;COPYRIGHT: (C)2002,JPO
