研究了不同漂移区长度及不同栅场极板长度的厚栅氧化层pLEDMOS器件由热载流子效应导致的导通电阻及阈值电压的退化现象及机理.实验结果表明,增加漂移区长度能改善器件的导通电阻的退化,但加速了阈值电压的退化;增加栅场极板长度可以同时改善导通电阻和阈值电压的退化.借助TCAD仿真软件,模拟分析了不同漂移区长度及不同栅场极板长度的pLEDMOS器件的离子产生率和纵向电场,模拟结果解释了各种退化现象的机理,同时表明碰撞电离率和纵向电场的优化是改善器件参数退化的有效手段.

对级联型氮化镓高电子迁移率晶体管(GaN HEMT)在非钳位感性负载开关(UIS)应力下的可靠性机理进行研究.通过实验分析和软件仿真验证,揭示级联型氮化镓功率器件在单脉冲UIS应力下的耐受机理、失效机理以及在多脉冲UIS应力下的电参数退化机理.在常开型氮化镓晶体管从开态转换到关态的过程中,器件源漏两端的电压增大.通过自配置级联的方式,观察器件内部节点的电压情况,从而分析其失效过程.实验结果表明器件的失效位置出现在低压硅基器件上,利用仿真软件分析得出逆压电效应引起关态漏电的增大,最终导致器件失效.此外,结合测试结果与仿真分析,发现重复UIS应力会引起电子陷阱的产生与积累,从而导致相关电参数的退化.

尽管2021年新冠病毒仍在肆虐,非小细胞肺癌(non-small cell lung cancer,NSCLC)的临床研究并未止步。得益于肺癌治疗模式的进步,NSCLC患者的总生存时间和生活质量得到了显著改善。目前靶向治疗与免疫治疗的研究进展改变了术后辅助治疗的现状,建立了可手术NSCLC治疗新标准。局部晚期和晚期NSCLC同样有重要的研究进展,包括新的治疗模式、新的治疗药物等,均为临床治疗带来更多选择。相信在可预见的未来,这些疗法都将为NSCLC的治疗带来改变,并逐步走向肺癌“慢病化”的道路。因此,本文简要综述了2021年改变肺癌治疗临床实践的重要研究以及值得关注的研究进展。

作者：刘超张春伟刘斯扬孙伟锋东南大学国家专用集成电路系统工程技术研究中心南京210096

A novel simulation program with an integrated circuit emphasis（SPICE） model developed for trench-gate metal-oxide-semiconductor field-effect transistor（M OSFET）devices is proposed. The drift region resistance was modeled according to the physical characteristics and the specific structure of the trench-gate MOSFET device. For the accurate simulation of dynamic characteristics, three important capacitances, gate-to-drain capacitance Cgd, gate-to-source capacitance Cgsand drain-to-source capacitance Cds, were modeled, respectively, in the proposed model. Furthermore,the self-heating effect, temperature effect and breakdown characteristic were taken into account; the self-heating model and breakdown model were built in the proposed model; and the temperature parameters of the model were revised. The proposed model is verified by experimental results, and the errors between measured data and simulation results of the novel model are less than 5%. Therefore, the model can give an accurate description for both the static and dynamic characteristics of the trench-gate MOSFET device.

某特种发动机复合材料壳体的基体树脂体系需要于55℃固化,而通常的低温固化环氧树脂体系虽可满足其固化温度的要求,但其耐热性和力学性能较差,难以满足用作复合材料树脂基体的性能需求。基于此,分别将具有不同分子结构的聚醚胺(MA223)、聚酰胺651(PA651)、异弗尔酮二胺(IPDA)三种固化剂与中温固化剂二氨基二苯基甲烷(DDM)的复配,研究其对于TDE-85环氧树脂体系的固化反应过程、耐热性及力学性能的影响。结果表明,三种低温固化剂和中温固化剂的适量配比即可使体系实现低温(55℃)固化。由于DDM分子中刚性苯环的引入,三种树脂体系的玻璃化转变温度高于通常低温固化体系,均在90℃以上;TDE-85/MA223/DDM体系的拉伸、弯曲、压缩性能均较佳且较均衡,TDE-85/PA651/DDM体系的力学性能适中,而TDE-85/IPDA/DDM分子中,由于DDM和IPDA分子刚性均较大体系缺少柔性链,除压缩性能较高外,拉伸性能和弯曲性能较差。综合考虑各方面性能,由于固化剂MA223的柔性分子链和芳香胺DDM的刚性苯环分子的互补匹配,使得体系具有良好的固化低温性、耐热性、力学性能,因而固化剂MA223可作为某特种发动机复合材料树脂体系的低温固化剂的首选。
