Then, by considering of the effects of field oxide and interconnects between devices, a two dimensional thermal model is developed. 在沟道热阻模型的基础上,考虑器件间场氧化层和金属互联线的影响,建立了非晶硅薄膜晶体管的二维热阻模型;
By modifying process for conventional RF LDMOS and introducing field oxide on the drift region, quasi-saturation effect of the device is reduced and performance of the device is greatly improved. 通过对传统RFLDMOS器件的工艺流程进行修改,并在漂移区上方引入场氧化层结构,改善了器件的准饱和现象。
The result shows that increasing the doping level below the bird's beak region and field oxide region, lower gate bias and reduction of the bird's slope are helpful to reduce lateral leakage current and enhance rad tolerant ability. 分析得出,增加鸟嘴和场氧区下的掺杂浓度、降低辐照栅电压、减小鸟嘴斜率均将有助于降低寄生泄漏电流,提高抗辐射能力。
