Abstract:
An inductor of a substrate burial type, a method for manufacturing the same, a micro device package, and a method for manufacturing a cap of a micro device package are provided to increase inductance by burying a coil electrode into a substrate. An inductor includes a substrate(110) and a coil electrode(120) formed by filling a hole(111) formed on the substrate with a metal. The coil electrode is formed with a linear spiral shape. The coil electrode is formed with a curved spiral shape. The substrate is formed with a silicon substrate. The coil electrode is formed with one selected from Au, Ag, and Cu. The inductor further includes an insulating layer(130) formed on the substrate and an external connecting pad(140) formed on the insulating layer in order to be connected with the coil electrode.
