Claim Text:
1. A high-frequency device, comprising: a substrate, comprising a first through-hole therein; a horizontal inductor having a first inductance, disposed on the substrate; and a first through-hole via inductor having a second inductance, disposed in the first through-hole of the substrate, wherein the first through-hole via inductor is formed by disposing a conductive pillar structure in the first through-hole of the substrate, wherein the top surface of the conductive pillar structure forms a first terminal of the first through-hole via inductor and the bottom surface of the conductive pillar structure forms a second terminal of the first through-hole via inductor, wherein the first through-hole via inductor is not a part of a spiral coil and one of the terminals of first through-hole via inductor is electrically connected to the horizontal inductor, wherein the second inductance of the first through-hole via inductor is greater than the first inductance of the horizontal inductor.
