Abstract

Disclosed is a silicon interposer that can reduce the entire area of a semiconductor package and increase the degree of integration by forming inductors at a lower part in addition to an upper part of a silicon substrate. The silicon interposer includes a silicon substrate, an upper inductor layer formed at the upper part of the silicon substrate and a lower inductor layer formed at the lower part of the silicon substrate.
