ABSTRACT It occurs that the performance of silicon bipolar transistors degradates seriously at low temperatures due to the gap-narrowing effect、the carrier freeze-out effect and the trapping effect of shallow dopants, which has significant influence on the operation of ultra-high-speed bipolar circuits and BiCMOS circuits at low temperatures.
硅双极晶体管由于禁带变窄效应,载流子冻析效应和浅能级杂质陷阱效应的作用,其电流增益和频率性能在低温下严重退化,从而极大地影响了低温高速双极电路和高性能的低温BiCMOS技术的发展。

Simultaneously, the exports of ionization rate and nonionzed concentration are set up as a powerful tool for studying thoroughly the freeze-out effect. dN〓/dp and dN〓/dn are neglected in the linearized equation system of the iteration methods of Newton and Gummel, due to having lower 15 orders or more than dN〓/dn and dN〓/dp, thus the computing effort is cut down with no effect on precision. A new cut-off technique is adopted to accelerate the convergence speed, about twice reduced for Newton iteration method and six times or so for Gummel iteration method. The approximate formulae of Fermi-Dirac statistics are also put forward with simpler form and higher precision. 3. A term dependent on time is added to the electron and hole current succession equations respectively. It is only this model that conservation of charge in transient analysis and alternating small-signal analysis at low temperature can be kept by. 4. The performance of SE-PISCES is explained by the simulation example of PISCES-2B, diode.
研究了低温半导体器件模拟的数值方法:对载流子浓度进行了新的归一化;编制了不考虑掺杂所引进的内建电场时的电离率计算程序;由于低温杂质电离率随偏压状态而变化,为此编制了每次求解迭代时的电离浓度计算程序,并将其插入到求解迭代程序中;同时,设置了杂质电离率和未电离杂质浓度的出口点,为更深入地研究冻析效应提供了有力工具;在Newton迭代法和Gummel迭代法的线性化方程组中忽略了dN〓/dp、dN〓/dn,是因为它们比dN〓/dn、dN〓/dp低15个数量级以上,这样减小了计算量又不影响模拟精度;对Newton迭代法和Gummel迭代法采取了新的截断技术,提高了收敛速度,Newton法迭代法和两次左右,Gummel法减少六次左右;给出了表达式更简单而精度更高的Fermi-Dirac积分近似计算公式。

Cells inosculation was carried out by standard method.The hybridoma supernatants were selected by indirect ELISA.The selected cells were subcloned three times by limiting dilution .Three hybridoma lines against TGEV rMP were obtained , which were designated as 1B3、3C2、4A5. The isotypes of the McAbs were IgG2a、IgG1、IgG1. The three hybridoma lines can secrete antibodies steadily after culturing and saving for a long time.
