Abstract

A transistor structure is provided, the transistor structure comprising a source, a drain, and a gate between the source and the drain. The gate may have a top surface. A first field plate may be between the source and the drain. The first field plate may be L-shaped and having a vertical portion over a horizontal portion. A top surface of the vertical portion of the first field plate may be at least as high as the top surface of the gate. A second field plate, whereby the second field plate may be connected to the gate and the second field plate may partially overlap the horizontal portion of the first field plate.
