An important feature in a vertical double-diffused metal oxide semiconductor field effect transistor (DMOSFET) is its ability to drive a load with minimal parasitic resistance at a given breakdown voltage. When the load is switched off, the maximum breakdown voltage is crucial. A DMOSFET produced using silicon carbide process material will have higher breakdown voltage than a DMOSFET produced in other process materials but often will have a higher parasitic resistance. Researchers at Purdue University have developed a structure and method of fabrication of a vertical DMOSFET in silicon carbide that achieves minimum on-state resistance and maximum breakdown voltage. Advantages: -Increases breakdown voltage without increasing internal resistivity -Provides consistent internal resistance at a greater operating temperature range Potential Applications: -Materials -Manufacturing |
