Abstract:
A MOSFET includes a semiconductor base substrate where a super junction structure is formed of an n-type column region and a p-type column region. A total amount of a dopant in the n-type column region is set to a value greater than a total amount of a dopant in the p-type column region. The MOSFET is configured to be operated during a period from a point of time when a drain current starts to decrease to a point of time when the drain current becomes 0 for the first time in response to turning off of the MOSFET such that a first period during which the drain current is decreased, a second period during which the drain current is increased or the drain current becomes constant, and a third period during which the drain current is decreased again occur in this order.

Claim (Index 4):
The MOSFET according to  claim 1 , wherein the semiconductor base substrate further includes: a p-type base region formed on a surface of a portion of the n-type column region and a whole surface of the p-type column region; and an n-type source region formed on a surface of the base region, and\n the MOSFET is a planar-gate-type MOSFET which further includes a gate electrode formed on the base region sandwiched between the source region and the n-type column region by way of a gate insulation film.
