  • Patent number: 9257221
    Abstract: The invention discloses a high-frequency device having a through-hole via inductor in a substrate. The through-hole via inductor has an integral body. The inductance of the through-hole via inductor is greater than that of the horizontal inductor. The through-hole via inductor comprises at least two materials, wherein one of said at least two materials is a conductive material. The present invention also discloses a method for manufacturing the structure of the high-frequency device, wherein the method mainly includes via-drilling and via-filling in the substrate, and lithography process on the substrate.

  • Patent number: 8884717
    Abstract: The invention discloses a diplexer formed from the combination of a first filter and a second filter, wherein both the first filter and the second filter have at least one through-hole via inductor. The diplexer has an input terminal to receive an input signal. The first filter has a first terminal electrically connected to the input terminal and a second terminal to generate a first output signal; the second filter has a third terminal electrically connected to the input terminal and a fourth terminal to generate a second output signal. The diplexer has a first output terminal electrically connected to the second terminal of the first filter to output the first output signal and a second output terminal electrically connected to the fourth terminal of the second filter to output the second output signal.

  • Publication number: 20130271251
    Abstract: The present invention discloses a substrate-less electronic component. A conductive element is disposed in the plurality of insulating layers, wherein the plurality of insulating layers are not supported by a substrate. The substrate-less electronic component can be manufactured by performing film process on a plurality of conductive layers or insulating layers on the substrate before the substrate is removed. In one embodiment, a buffer layer can be formed on the substrate. After the process is done, the buffer layer can be easily removed to decouple the substrate from the layers on the substrate.
