摘 要:
对具有埋层结构的集成大功率器件提出了导通电阻自限制二维模型。在假定条件成立时,推导出器件二维模型导通电阻自限制公式,得出了具有埋层结构的集成大功率器件结构其比导通电阻是随着面积不断增大的结论。通过实验,证实了该结论预测趋势的正确性。该结论对类似集成化大功率器件结构设计具有一定的指导作用。[著者文摘]

Abstract:
An on-resistance self limitation 2-D model for integrated power devices with buried layer is proposed. When hypothetical conditions were met, formula of the on-resistance 2-D model is derived. It is concluded that, for integrated power device with buried layer, the specific on-resistance increases with device ares The correctness of the conclusion for trend prediction has been demonstrated by experiments.[著者文摘]
