摘要
文章对薄膜双栅MOSFET器件的温度特性进行了研究。首先对其进行理论分析,得到亚阈值电流、阈值电压和饱和电流等随温度的变化关系,并计算出理论结果,再用Medici模拟仿真加以验证,比较了不同温度下的输出特性、饱和漏电流、阈值电压与温度变化的关系,验证结果表明两者是一致的。
The temperature characteristics of thin-film double-gate MOSFET are studied in this paper. Firstly, the change of the subthreshold current, threshold voltage and saturation current with the temperature is calculated theoretically. Then by using Medici model, the separate differences of out- put specification, saturation drain current and threshold voltage under different temperatures are ana- lyzed. It is shown that the theoretical results are in accordance with the simulation ones.
