    Greetings,



    Can threshold voltage and gate length be varied concurrently? Is it possible to consider simultaneous 3 sigma variations for both these parameters during modeling? Or these two parameters correlated (correlation coefficient must be considered)?

    The general answer is yes. There are a number of factors that affect threshold voltage and gate length is one of them. How much gate length can affect threshold voltage depends on the process and gate length restrictions.

    I'm not a process guy or a statistician...
