What happens to capacitance after fingering MOS transistor?

capacitance

By doing 'fingering' of MOS transistor what will happened to "CAPACITANCE".
i think resistance will reduce becoz poly will connect in parallel.

but what about capacitace?

Re: capacitance

because of the sharing of the source and drain.the parasitic source and drain capacitance is reduced.the gate capacitance is WLCox +Cov ,so it doesn,t change.
