Abstract
An LDMOS includes a semiconductor substrate. A well is disposed within the semiconductor substrate. A body region is disposed within the well. A first gate electrode is disposed on the semiconductor substrate. A source electrode is disposed at one side of the first gate electrode. The source electrode includes a source contact area and numerous vias. The vias connect to the source contact area. The vias extend into the semiconductor substrate. A first drain electrode is disposed at another side of the first gate electrode and is opposed to the source electrode.
