ABSTRACT:
Disclosed is a noise shield type multi-layered substrate which is advantageous in terms of shielding leaked magnetic flux and cross-talk by disposing a magnetic material onto at least one of circuit patterns, passive components and active components, thus blocking noise generated from the circuit patterns, passive components and active components. Thus, malfunctions of neighboring circuit patterns and various parts due to leaked magnetic flux are prevented. A method of manufacturing the noise shield type multi-layered substrate is also provided.
