IPC: H01L29/78
Filed: 2001-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device, whose durability can be increased during the operation of an inductance load by setting the concentration of a P-type semiconductor region low. SOLUTION: On a silicon substrate 10, an N<-> -type semiconductor region 11, a P-type semiconductor region 12, and an N<+> -type semiconductor region 13 are formed. The P-type semiconductor region 12 is so formed that the carrier concentration is reduced and thereby the entire region becomes a depletion layer 30. Thus, the operation of an NPN-type transistor formed inside the silicon substrate 10 is suppressed by a surge voltage generated by counter electromotive force during the operation of the inductance load. Consequently, the breakdown of elements formed inside the silicon substrate 10 can be prevented, increasing the durability during the operation of the inductance load.
