Patent ID: RE39124

Claim:
An integrated circuit, comprising: a first supply track to be connected to a first supply potential; a second supply track to be connected to a second supply potential, the first supply potential and the second supply potential supplying a supply voltage, said first supply track and said second supply track forming a first metallic layer; at least one second metallic layer having at least one third supply track to be connected to one of the first supply potential and the second supply potential and disposed in each case above said first metallic layer; at least one first capacitive element disposed below said first metallic layer; and at least one second capacitive element defined by said at least one third supply track and at least one of said first supply track and said second supply track; said at least one first capacitive element and said at least one second capacitive element being connected in parallel and smoothing over the supply voltage; said at least one first capacitive element being one of a plurality of first capacitive elements disposed below both said first supply track and said second supply track, and said at least one second capacitive element being one of a plurality of second capacitive elements; said second capacitive elements each having a capacitance and said first capacitive elements each having a capacitance being at least a factor of 10 greater than said capacitance of said second capacitive elements.
