Need PSpice model for CMOS 0.81u process

HI,
I'm looking for A Spice model for CMOS 0.81u process.
If so , plz forward
tahnks

pspice cmos

any process is 0.81u cmos?
or 0.18u cmos?

E-mail to Chartered Semiconductor, TSMC or UMCi or even some Indian foundries (if any on the Internet) for 0.18-µm CMOS models for digital, analog and RF. They usually reply in more than a week if slow or less than a day if fast. Their models are accurate to their processes only.

You can e-mail to Berkeley BSIM Group directed by Professor Hu. They can offer you some models which they think is accurate. Because it is a research group, not an industrial organisation, they might ask if you are looking for 1st order, 2nd order, or unified models or whatever models they have available.

You can also e-mail to Infineon and Philips for European CMOS models. They also very accurate too.

Added after 2 minutes:

STMicroelectronics too have their CMOS models. You can e-mail them as well.

Renesas Technology (Japan) and Samsung-Hyundai too have CMOS models.

Micron too has CMOS models.

E-mail them if you want.

Thanks for fast reply
That is true 0.18u not 0.81u

well, when i use BSIM3 model parameter ,the PSpice cann't simulate and error come out , where if I change the LEVEL form 49 to 6 in the model parameter the simulator work, can you explain that?
also are all parameter of that model are used? , what VERSION stand for in the model parameter? finally how we justify the result mathmatically (can we use squar law?).
thanks

Numbers of refered MOS Level in difference SPICEs are also different i.e. Level 49 in Hspice and Level 7 in Pspice mean the same thing that is BSIM3v3 model.

For tip to convert Level 49 HSPICE models to Level 7 PSpice models can be found here. www.mosis.org/Faqs/pspice.pdf
