Zusammenfassung:A structure includes channel regions located between source/drain regions, and a polysilicon gate structure including a plurality of gate fingers, each extending over a corresponding channel region. Each gate finger includes first and second rectangular portions extending in parallel with a first axis, and a connector portion that introduces an offset between the first and second rectangular portions along a second axis. This offset causes each source/drain region to have a first section with a first length along the second axis, and a second section with a second length along the second axis, greater than the first length. A single column of contacts having a first width along the second axis is provided in the first section of each source/drain region, and a single column of contacts having a second width along the second axis, greater than the first width, is provided in the second section of each source/drain region.
