Patent ID: 7859039

Claim:
A semiconductor capacitor structure comprising: a first metal layer, the first metal layer comprising: a first portion comprising a first section and a plurality of parallel-arranged second sections coupled to the first section; and a second portion comprising a third section and a plurality of parallel-arranged fourth sections coupled to the third section, the plurality of second sections and the plurality of fourth sections interdigitate in parallel; a second metal layer, the second metal layer comprising: a third portion comprising a fifth section and a plurality of parallel-arranged sixth sections coupled to the fifth section; and a fourth portion comprising a seventh section and a plurality of parallel-arranged eighth sections coupled to the seventh section, the plurality of sixth sections and the plurality of eighth sections interdigitate in parallel, and the plurality of sixth sections and the plurality of second sections are not in parallel; a first set of via plugs for electrically connecting the plurality of second sections to the plurality of sixth sections; a second set of via plugs for electrically connecting the plurality of fourth sections to the plurality of eighth sections; and a dielectric layer formed between the first metal layer and the second metal layer; wherein the first section and the third section of the first metal layer do not overlap with any sections in the second metal layer.
