Abstract
A semiconductor device has transistors, each transistor having a first conduction type of a first semiconductor region including a first main electrode region, a second conduction type of second semiconductor region including a channel region which is provided in the first semiconductor region, a second main electrode region provided in the second semiconductor region, a gate electrode on the channel region extending through a gate insulating film between the first and second main electrode regions. A portion of the first main electrode region which contacts the channel region is a high-resistance region. The semiconductor device also has buried-type element isolation regions which prevent the occurrence of latch up and bird'"'"'s beaks in the device.
