Temperature characteristics of a new 100V rated power MOSFET, VLMOS (vertical LOCOS MOS)

In this paper, we proposed a new 100 V rated power MOSFET, called "VLMOS (vertical LOCOS MOSFET)", and investigated characteristics of the VLMOS under high temperature. From simulation and experimental results, we verified that it overcame the "Si limit" and had superior temperature characteristics in specific on-resistance. This means that the VLMOS is excellent for wide-temperature range operations, especially for automotive applications.
