FinFET model parameter

Saeed Gharagoz
I have a FinFET model parameter and I need to use to simulate a circuit. How can I do it? Should I only change the file extension from .pm to .scs and copy it where everything else is? Or should modify the existing file? And any idea where can I get 22nm MIGFET model? Thanks

  • Hello~I download 32nm model of finfet from website http://ptm.asu.edu/.

    .param pnch = 2e16                       nch = ??? (what nch means?)
    .param ptox = 1.4e-9     we know  tox = Oxide thickness
    .param ptsi = 'tbsi'                           tsi = Fin thickness
    .param ptbox = 1.4e-9                   
    .param npvthf0 = 0.29                     npvthf0 = ???
    .param npvthb0 = 0.29
    .param esi = 11.7                            esi = ???
    .param eox = 3.9                             eox = ???
    .param nlambda1 ='(-1)*(ptox/(ptbox+ptsi/(esi/eox)))'
    .param nlambda2 ='(-1)*(ptbox/(ptox+ptsi/(esi/eox)))'

    .param delta1 = 0.008
    .param delta2 = 0.008

    .param Voff2=-0.09
    .param N = 0.2
    .param Vt = 0.0259
    .param Voff1 = 0.0

    I have a FinFET model parameter and I want to use to simulate a circuit.

    I want to change some parameters from the table. (like  .param ptox = 1.4e-9 => .param ptox = 1.6e-9)  How can I do it?
