TRANSISTORS HAVING BURIED P-TYPE LAYERS COUPLED TO THE GATE AND METHODS OF FABRICATING THE SAME

摘要

A unit cell of a metal-semiconductor field-effect transistor (MESFET) is provided. The MESFET has a source, a drain and a gate. The gate is between the source and the drain and on an n-type conductivity channel layer. A p-type conductivity region is provided beneath the gate between the source and the drain. The p-type conductivity region is spaced apart from the n-type conductivity channel layer and electrically coupled to the gate. Related methods are also provided herein.
