Abstract:
1. A metal capacitor, comprising: a first plurality of L-shaped fingers, residing on a first layer of a semiconductor substrate, connected together and driven to a first voltage level by a first interconnect segment; a second plurality of L-shaped fingers, residing on the first layer of the semiconductor substrate, connected together and driven to a second voltage level by a second interconnect segment; a third plurality of L-shaped fingers, residing on the first layer of the semiconductor substrate, connected together and driven to the first voltage level by a third interconnect segment; and a fourth plurality of L-shaped fingers, residing on the first layer of the semiconductor substrate, connected together and driven to the first voltage level by a fourth interconnect segment, wherein the first interconnect segment, the second interconnect segment, the third interconnect segment, and the fourth interconnect segment have a same length, have a same width, reside on the first layer of the semiconductor substrate, and are physically detached from each other on the first layer, wherein the first interconnect segment, the second interconnect segment, the third interconnect segment, and the fourth interconnect segment form a square configuration.
