摘要： A surface between gate electrodes in an MOS gate structure is patterned so that missing portions are partially provided in surfaces of n+ emitter regions to thereby enlarge surface areas of p+ contact regions surrounded by the surfaces of the n+ emitter regions. In this manner, a highly reliable MOS type semiconductor device is provided which is improved in breakdown tolerance by suppressing an increase in the gain of a parasitic transistor caused by photo pattern defects produced easily in accordance with minute patterning in a process design rule.
