    Question about Lmin and Leff in 90nm process

    When we talk about 90nm process, what do we mean by this. Does it mean that minimum channel length (Ldrawn) is 90nm? or Ldrawn is 180nm? In attached image from a journal paper [1], author is referring to 90nm process, but has mentioned that L=46nm. But previously we knew that according to...

    90 nm process paramerters, what is Wd in spice model?

    I need process parameters to get the following: sigma_vth = (q* tox / eox ) * sqrt (Na*Wd / (3*L*W)) ---[1] where tox is oxide thickness Na is effective channel doping Wd is the depletion region width Now, I have 90 nm spice parameters, but I do not know which parameters represent these...

    Standard deviation of threshold voltage

    Hi, I want to do the variability analysis on my design and hence I need sigma of vth and u0 (standard deviation of threshold voltage and mobility) for monte carlo simulations. I have the 90nm PDK as well, but I dont know where these values are written. Can you please tell me how to get these...

    Difficulty with Spice Models. Which model to use?

    I am going through MOSIS and I find two different spice models (BSIM4) for 90nm (hopefully for two different specialized processes). https://www.mosis.com/cgi-bin/cgiwrap/umosis/swp/params/ibm-90/t96w_9sf_9m_lb_3-params.txt and...
