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.
