Patent ID: 8847080

Claim:
A multilayer wiring board comprising: a low resistance silicon substrate including an electric passage part surrounded by a ring-shaped groove having a depth equal to a thickness thereof; a first insulating layer laid on a main face on first side of the low resistance silicon substrate and formed with a first opening penetrating therethrough in the thickness direction so as to correspond to the electric passage part; and a high resistance silicon substrate laid on a main face on the first side of the first insulating layer and formed with a first recess having a depth equal to a thickness thereof so as to correspond to the first opening; wherein the low resistance silicon substrate has a predetermined resistivity, and the first high resistance silicon substrate has a resistivity higher than the predetermined resistivity; and wherein a first wiring film is disposed on a main face on the first side of the first high resistance silicon substrate and an inner face of the first recess while interposing a first insulating film, and the first wiring film is electrically connected to the electric passage part through the first opening.
