Abstract

A semiconductor device includes a semiconductor substrate with an upper surface and a channel, source and drain electrodes over the upper surface of the semiconductor substrate, a passivation layer between the source and drain electrodes, a first dielectric layer over the passivation layer, a gate electrode between the source and drain electrodes, and a conductive field plate adjacent to the gate electrode. The passivation layer includes a lower passivation sub-layer and an upper passivation sub-layer over the lower passivation sub-layer. The gate electrode includes a lower portion that extends through the passivation layer. The conductive field plate includes a first portion with a recessed region that extends through the upper passivation sub-layer but does not extend through the lower passivation sub-layer, and an overhanging portion that extends over an upper surface of the first dielectric layer.
