Abstract
The super-junction semiconductor device, which facilitates increased switching speed and reduced on-resistance, includes an alternating conductivity type layer formed of n-type drift regions and p-type partition regions arranged alternately, a pair of the n-type drift region and p-type partition region repeating at a first repeating pitch, and trenches each containing a gate electrode buried therein, the trenches being arranged repeatedly at a second repeating pitch wider than the first repeating pitch. The device further includes one or more n-type channel regions between a p-type partition regions and a p-type well region.
