Classification: CPC H | IPC H

Claim 0:
1. A Group III nitride-based transistor device, comprising:
a source electrode, a drain electrode and a gate electrode positioned on a first major surface of a Group III nitride based-based layer, wherein the gate electrode is laterally arranged between the source electrode and the drain electrode;
a passivation layer arranged on the first major surface;
a field plate electrically coupled to the source electrode, the field plate having a lower surface arranged on the passivation layer, the field plate being laterally arranged between and laterally spaced apart from the gate electrode and the drain electrode,
wherein the source electrode, the gate electrode, the drain electrode and the field plate each have an elongate form and extend on the first major surface in a longitudinal direction substantially parallel to one another; and
a conductive redistribution structure arranged above the source electrode, the gate electrode, the drain electrode and the field plate and comprising a lateral gate redistribution structure and a lateral field plate redistribution structure that are substantially coplanar at a position laterally between the source electrode and the drain electrode.
