for 0.18u technalogy how much gate voltage required for oxide breakdown???

Regards
 

check your technology documentation or just sweep it in simulation until you see the warning message comes up.

Genarally for 1.8V 0.18u tech, the oxide breakdown is about 3V.... Anyway, it is very much depend on the process that you are using
 

szekit, as my experience, simulation can't give the answer of gate oxide breakdown volt. So, check the fab's EC table to find the maximun rating.

For .18 process, 2.5 to 3 volts will be danger.

u may see the process specification document, and the gate oxide breakdown voltage is specified in the document. This document should be supported by ur foundry.
 

Oxide voltage breakdown is about 0.8 ... 1.0 V / nm.
Oxide thickness is about 3 nm for 0.18 um technology.
So 3 nm * ( 0.8 ... 1.0 ) V / nm = 2.4 ... 3.0 V .
 
what happen if there's transient spike (~10us) of 3 to 4V on the 0.18um devices during power up and power down? does it pose any dangerous?
