INTERDIGITATED INTEGRATED CIRCUIT CAPACITOR

摘要

The invention relates to the field of microelectronics, more particularly to the structure and layout of integrated circuit capacitors. An integrated circuit capacitor is provided comprising: a first conductive component comprising a plurality of digital sub-components; and a second conductive component comprising a plurality of digital sub-components; wherein the digital sub-components of the first and second conductive components are interleaved and parallel, with a narrow uniform distance therebetween; and wherein the orientation of the interleaved digital sub-components is symmetrical about the center of the integrated circuit capacitor. This symmetrical orientation aids in the creation of a capacitor with well-matched top and bottom plates and capacitor pairs that have well-defined ratios. The arrangement serves to minimize the photolithographic variations by averaging the offsets caused by the different lithographic traces.
