High Electron Mobility Transistors (HEMTs) are described with a circular gate, with a drain region disposed within the circular gates and circular source region disposed around the circular gates. The circular gate and the circular source region may form complete circles.

Non-linear HEMT devices

In an embodiment, a HEMT is formed to have a main transistor having a main active area and a sense transistor having a sense active area. An embodiment may include that the main active area is isolated from the sense active area.

In a general aspect, a semiconductor device can include a plurality of vertical transistor segments disposed in an active region of a semiconductor region. The plurality of vertical transistor segments can include respective gate electrodes. A first dielectric can be disposed on the active region. An electrically conductive grid can be disposed on the first dielectric. The electrically conductive grid can be electrically coupled with the respective gate electrodes using a plurality of conductive contacts formed through the first dielectric. A second dielectric can be disposed on the electrically conductive grid and the first dielectric. A conductive metal layer can be disposed on the second dielectric layer. The conductive metal layer can include a portion that is electrically coupled with the respective gate electrodes through the electrically conductive grid using at least one conductive contact to the electrically conductive grid formed through the second dielectric.
