    hello,

    I as wondering if anyone could direct to me to any good links
    describing the different layers that are used to perform vlsi design.
    I am familiar with most of them, but I could not find anywhere what
    the NFIELD layer is. It is not NWELL, but it mirrors it in all the
    places where there is NWELL. I suspect it is suppose to indicate that
    the location of lightly doped n. Can anyone confirm this? How is it
    different with NWELL?

    P.S The technology is: for xfab 0.35um XC035LV cmos. See document :
    http://www.xfab.com/xfab/frontend/img_db/dl_mg_1064582343.pdf

    page. 3

    Thx.
    -Frank
