Well proximity parameters (scc,scb,scc) used in PLS simulation

anandmohan

HI,

Can anyone tell me how the well proximity parameters are used in model file (.scs)  while running PLS simulation?

My requirement is to find out how (WPE) well proximity parameters (scc,scb,scc) effects the threshold voltage of device. I have gone through the model file (.scs) already but I am not seeing any direct relation b/w the WPE parameters and threshold voltage. But in PLS simulation I can see that with WPE parameters variation my device resistance is getting varied. So I need to know how threshold voltage is modeled based sca,scb,scc parameters.

Regards

Anand

    Anand,

    This is covered in the Spectre® Circuit Simulator Components and Device Models Reference manual in the chapter for whichever device model you're using. In SPECTRE161 if the model is bsim4, there's a section in Chapter 21 called "Well Proximity Effect Model" which describes this.

    Regards,

    Andrew
