| 摘 要： | 提出了一种具有积累层沟道的槽栅IGBT结构。仿真结果表明：在阻断电压为1200V，集电极电流密度为100 A/cm2，温度分别为300K和400K下的情况下，积累层沟道槽栅IGBT的正向压降分别为1.5V 和2V而常规槽栅IGBT分别为1.7V和2.4V。新结构比常规槽栅IGBT具有更低的开态压降和更大的正向安全工作区。文中同时分析了积累层沟道槽栅IGBT的阻断特性和关断特性。

| Abstract: | An accumulation channel trench gate insulated gate bipolar transistor (ACT-IGBT) is proposed. The simulation results show that for a blocking capability of 1200 V, the on-state voltage drops of ACT-IGBT are 1.5 and 2 V at a temperature of 300 and 400 K, respectively, at a collector current density of 100 A/cm2. In contrast, the on-state voltage drops of a conventional trench gate IGBT (CT-IGBT) are 1.7 and 2.4 V at a temperature of 300 and 400 K, respectively. Compared to the CT-IGBT, the ACT-IGBT has a lower on-state voltage drop and a larger forward bias safe operating area. Meanwhile, the forward blocking characteristics and turn-off performance of the ACT-IGBT are also analyzed. |
