LAYOUT TECHNIQUES AND OPTIMIZATION FOR POWER TRANSISTORS

Abstract:

Various embodiments are disclosed for improved and structurally optimized transistors, such as RF power amplifier transistors. A transistor may include a drain metal portion raised from a surface of a substrate, a drain metal having a notched region, a gate manifold body with angled gate tabs extending from the gate manifold, and/or a source-connected shielding. The transistor may include a high-electron-mobility transistor (HEMT), a gallium nitride (GaN)-on-silicon transistor, a GaN-on-silicon-carbide transistor, or other type of transistor.
