US 2013/0278372 A1 · Semiconductor Component with Coreless Transformer

Abstract

A semiconductor component has integrated a coreless transformer with a first connection contact, a second connection contact, an electrically conductive spiral first coil, an electrically conductive first ring, and an electrically conductive second ring. The electrically conductive spiral first coil is electrically connected between the first connection contact and the second connection contact. The electrically conductive first ring surrounds the first coil and one or both of the first connection contact and the second connection contact. The electrically conductive second ring is arranged between the first coil and the first ring, electrically connected to the first coil, and surrounds the first coil and one or both of the first connection contact and the second connection contact.
