How can capacitance of a gate be reduced?

The capacitance of a gate can be decreased by decreasing their areas or increasing the thickness of the insulating layers. The most effective method is to minimize the area of the capacitors by scaling down the devices. Scaled devices have smaller capacitance values because of their size shrinking.
