oxide thickness.......

why oxide thickness wont be<25nm......why ckt wont work if it is less......
 

Re: oxide thickness.......

I assume you are asking about SiO2 used as gate oxide. I'm not sure if 25nm is really a turning point, but the main issue is that with decreasing oxide thickness, leakage currents will increase. New technology nodes (<=45nm) will rely on hafnium based gate oxides, which exhibit much lower leakage currents.
Does that answer your question?

Regards,

C.
