    why there should be n well spacing

    Hi
    Why is that nwell spacing is required. What happens if I dont give ? Dont tell me that it is in the rule book and thats why we are giving

    wells at different potential needs to be apart orelse it will be in same potential shorting wells

    where should there be N spacing

    CMOS and most devices have spacing to prevent the internal shorting

    Re: why there should be n well spacing

    There's a manufacturability gap where you can't reliably
    pattern below a certain spacing. Zero gets merged, any
    as-printed spacing less than your well depth has a chance
    of the implant drive connecting them anyway.

    Then there's the question of just what a narrow-base
    lateral NPN looks like, to your circuit.

    So you say that it forms an extra npn transistor which is unintended right? Thats the reason we give spacign and one more is the manufacturability thing.
    Thanks for the answer dick
