ABSTRACT:
A semiconductor device has an electrical circuit and a grounding terminal. A multilayer substrate has a plurality of insulator layers and conductor layers in a stacked arrangement and a surface with first and second regions, the conductor layers making electrical contact with the electrical circuit and the grounding terminal of the semiconductor device. The first region generally surrounds the semiconductor device and has first connecting conductors penetrating at least a part of the multilayer substrate so that each of the first conductors makes contact with one or a plurality of corresponding conductor layers. The second region generally surrounds the first region and has second connecting conductors penetrating at least a part of the multilayer substrate and only making contact with one or a plurality of conductor layers coupled to the grounding terminal of the semiconductor device.
