Abstract:
1. A method of making capacitor structure, the method comprising: arranging a first-layer first-polarity conducting strip and a first-layer second-polarity conducting strip on a first layer of an integrated circuit chip such that the first-layer second-polarity conducting strip is arranged adjacent to and spaced apart from the first-layer first-polarity conducting strip, and the first-layer first-polarity conducting strip and the first-layer second-polarity conducting strip are arranged as respective piecewise spirals; arranging a second-layer first-polarity conducting strip and a second-layer second-polarity conducting strip on a second layer of the integrated circuit chip such that the second-layer second-polarity conducting strip is arranged adjacent to and spaced apart from the second-layer first-polarity conducting strip, the second-layer first-polarity conducting strip and the second-layer second-polarity conducting strip are arranged as respective piecewise spirals, the second-layer second-polarity conducting strip is arranged overlying and electrically separated from the first-layer first-polarity conducting strip, and the second-layer first-polarity conducting strip is arranged overlying and electrically separated from the first-layer second-polarity conducting strip; electrically connecting the first-layer first-polarity conducting strip with the second-layer first-polarity conducting strip; and electrically connecting the first-layer second-polarity conducting strip with the second-layer second-polarity conducting strip.
