Three hypotheses is put forward, based on microexamination about sample evaporation during determaination of isotope abundance by thermal ionization:1. Only atoms uncovered by outer layer atoms can be vapoured; 2. Atoms covered by outer layer atoms can diffuse but cannot vapoure; 3. The probability of diffusion of isotope atoms is in direct proportion to its probability of evaporation.

Inversion holes caused by the vertical electric field EV/ are located in the spacing of two neighboring nC-regions on the interface by the force from lateral electric field (EL/ and the compositive operation of Coulomb's forces with the ionized donors in the undepleted nC-regions. This effectively enhances the electric field of dielectric buried layer EI/ and increases breakdown voltage

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。
