Abstract
In one example, an integrated circuit comprises a transistor and a metal layer. The transistor has an insulator layer over a substrate that includes gallium nitride (GaN). First and second opening in the insulator layer respectively define a drain region and a source region of the transistor. A gate electrode extends into the insulator layer between the source region and the drain region. The metal layer includes a drain via and a source via. The drain via extends through the first opening to the drain region. The source via extends through the second opening to the source region. A source field plate is in the metal layer. The source field plate extends over the gate electrode and provides a contiguous electrically conductive path to the source region.
