研究了高压SOI—LIGBT器件的单脉冲正偏安全工作区(FBSOA)的绘制方法。首先,分别提取器件的热阻与热容,并借助热阻抗公式计算器件的瞬态热阻抗,进而根据热阻抗与最大允许功率之间的关系,获得直流与脉冲条件下的正偏安全工作区。同时,还对其二次击穿边界与安全工作区的相互关系做了进一步分析,为更加准确地确定高压LIGBT器件的单脉冲安全工作区提供理论指导。

The plotting method of single pulse forward bias safe operating area (FBSOA) on the high voltage SOI-LIGBT is investigated in this paper. Firstly, the thermal resistance and thermal capacitance are extracted separately, and then the transient thermal impedance can be calculated based on the extracted values. Moreover, the FBSOA at DC and pulse conditions could be obtained by the relation between maximum power dissipation and the thermal impedance. Meanwhile, the relations between the second break down location and FBSOA are analyzed further, which gives the theoretic instructions for plotting FBSOA of high voltage SOI-LIGBT more accurately.
