METAL-SEMICONDUCTOR FIELD EFFECT TRANSISTORS (MESFETS) HAVING DRAINS COUPLED TO THE SUBSTRATE AND METHODS OF FABRICATING THE SAME

摘要

The present invention provides a unit cell of a metal-semiconductor field-effect transistor (MESFET). The unit cell of the MESFET includes a MESFET having a source region, a drain region and a gate contact. The gate contact is disposed between the source region and the drain region. The drain region is electrically coupled to the substrate through a contact via hole to the substrate. Related methods of fabricating MESFETs are also provided herein.
