[solved] Are Dual Contacts mandatory?
Hi,
I'm doing the layout for some circuits for the H35B4 Technology from AMS. Normally I use multiple contacts when layout transistors (e.g. for drain, source etc.), but now I have an inverter that is pretty small (0.8 over 0.35 and 0.4 over 0.35). Should I layout the thing with also two contacts per terminal? Until now I never had the problem, since the transistors where not that small...
We learned to use multiple vias when switching metal layers, there it is not a problem, here it starts to look really awkward, since the contact have a minimum size of 0.4...
Regards,
Andreas
