Title: Difference between N/P –select and n/p - active layers in CMOS layout techniques
Post by VINAY RAO on Feb 23^rd, 2012, 11:48pm

Hi,
What is the significance of using n/p select layers along with n/p active layers to make a CMOS active device? Why we need to draw extra n/p select layers though we can distinguish P and N regions just by using P/N active regions?

Regards,
Vinay Rao.

This isn't a simulator question. Perhaps you should have posted it in "Physical Verification, Extraction and Analysis" ?
