What's the normal permittivity and conductivity of P-substrate of CMOS technology?

Hi,
What's the normal permittivity and conductivity of P-substrate of standard CMOS technology, such as 130nm?
Thanks a lot.

Why do you care them?

Re: P-substrate

because I need to simulate an on chip inductor on lossy silicon substrate.

Usually, the foundry has designed the model of on chip inductor.

I use the on chip inductor frequently, but never do as you said.

So I　ｓｏｒｒｙ　Ｉ　ｃａｎ＇ｔ　ｈｅｌｐ　ｙｏｕ．

Ok, thanks anyway.

Re: P-substrate

it depends on the substrate u wrkin on whether lightly doped or heavily doped substrate.

it's a kind of company secret.
