Abstract
A first interconnect substrate includes a first conductor pattern. A second interconnect substrate includes a second conductor pattern. At least a portion of the second conductor pattern is formed in a region opposite the first conductor pattern. At least either the first conductor pattern or the second conductor pattern has a repeated structure. The first conductor pattern and the second conductor pattern constitute at least a portion of an electromagnetic band gap (EBG) structure.
Claims25
An electronic device comprising:
- a first interconnect substrate;
- and
- a second interconnect substrate connected to the first interconnect substrate,
- wherein the first interconnect substrate includes a first conductor,
- the second interconnect substrate includes a second conductor of which at least a portion is formed in a region opposite the first conductor,
- the second conductor forms a repeated structure of conductors, and
- the second conductor is electrically isolated from other conductors included in the second interconnect substrate.

A noise suppression method comprising:
- providing a first conductor in a first interconnect substrate over which electrical parts are to be mounted;
- providing a second conductor in at least a portion of a region in a second interconnect substrate, the region being opposite the first conductor, wherein the first interconnect substrate and the electrical parts are to be mounted over the second interconnect substrate;
- and
- forming a repeated structure in at least either the first conductor or the second conductor, and forming at least a portion of an electromagnetic band gap (EBG) structure by the first conductor and the second conductor, the method being preventing a noise from propagating through a space between the first interconnect substrate and the second interconnect substrate.
