IPC: H01L27/04
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide an insulated gate semiconductor device, whose safe operation region can be enlarged and switching operation is carried out uniformly, without impairing low current loss by a method, wherein a trench gate electrode is divided into plural sets of electrodes, and the sets of electrodes are driven separately with different control signals. SOLUTION: A gate section is divided in two gates, insulated gates 11 and 12, where the insulated gate 11 is connected to a gate wiring 21, and the insulated gate 12 is connected to a gate wiring 22. The two insulated gates 11 and 12 are controlled by two gate signals. That is, before an insulated gate semiconductor device is turned off, only the insulated gate 12 is turned off, by giving a voltage lower than a gate threshold Vth to it, and then the insulated gate 11 is turned off to turn an entire devices to off. Owing to this structure and a drive method, the device is capable of carrying out a switching operation, stably keeping an on-state voltage low as in conventional cases. That is, a storage carrier density is lessened around an embedded gate before the device is turned off, and a gate section can be lessened in electrostatic capacity at the same time.
