Insulated gate semiconductor device |
| abstract |
(57) [Summary]n[Purpose] To reduce on-voltage.nA gate electrode is provided on an upper main surface of a semiconductor substrate. A stripe-shaped groove 207 embedded with 210 is formed. Semiconductor substrate 200 sandwiched between adjacent grooves 207 The upper main surface has N + Emitter layer 206 is exposed like a ladder are doing. Therefore, at the contact surface with the emitter electrode 212, Even if the position of a certain band-shaped region Ra is shifted, the emitter electrode 21 2 is N + It makes reliable contact with the emitter layer 206. Also, Ladder-shaped N + The emitter layer 206 is adjacent to the groove 207. The channel region 208 is formed Is formed along the line.n[Effect] It is easy to miniaturize the element. In addition, miniaturization effectively contributes to a reduction in on-voltage. |
