Abstract:
1. A semiconductor device, comprising: a second conductive type first semiconductor region; a first conductive type second semiconductor region embedded in a part of an upper surface of the first semiconductor region; a second conductive type source region embedded in a part of an upper surface of the second semiconductor region; a second conductive type drain region embedded in a part of the upper surface of the first semiconductor region separated from the second semiconductor region; a gate electrode located on the second semiconductor region between the source region and the drain region; an insulation film located on the first semiconductor region between the second semiconductor region and the drain region; a voltage dividing element which is located on the insulation film and configured to divide a voltage between the gate electrode and the drain region; and a charge transfer limiting element connected between the voltage dividing element and the drain region and configured to limit transfer of charge from the voltage dividing element to the drain region.
