Wells and diffusions

[NaveenNavi]

How to do I know the length of the n+ and p+ diffusions ? and how do I know the depth and length of a n well? Any website or link to research about that and the parameters related to that?

The absolute value of these parameters are technology dependent. One should be able to obtain them from PDK documents or asking the concern foundry for them in specific.

Generally, Length of n+ and p+ diffusion are significantly dependent on the W & L of the Mosfet. You can get a feel of this dependence from the spice model file.
