Dear Folks,

I am using the IBM 0.13um CMRF8SF design kit DM option. The transistors (pfer & rfet) auto-generated by IBM in layout contain such errors:

1) The auto-generated contact (CA) to finger poly (PC) is less than 0.14um

2) The auto-generated contact (CA) to RX is less than the minimum extension distance.

I use the "Recommended" DRC, it will give me errors.

Could somebody please explain? This is Urgent and the fab deadline is coming!

Thank you.
 

Ask your fab. They usually "waive" (sanction) such DRC violations caused by their own layouts -- not those caused by yours! Perhaps they suggest to use a relaxed DRC rules set instead of the recommended one.
