how are MOSFET device models derived....PDK's

[bhanu.somisetty]

Hi all,

any one tell me "how are PDK's made,for Transistors?i meant to ask how are mos device models made,which are used for circuit simulations?

Thanks

In brief:
When a process is being characterized, MOSFETs of different W/L's are fabricated and various voltages and currents applied and their responses measured using high precision equipment. The captured data is then used to build compact models (BSIM3 for MOSFETs etc) using tools like Agilent IC-CAP.

Thanks a lot..if you have any material on how PDK's are made,i request you to pls upload...
