Integrated circuit including at least six linear-shaped conductive structures forming gate electrodes of transistors with at least two different extension distances beyond conductive contacting structures
Abstract:
A cell of a semiconductor device is disclosed to include a diffusion level including a plurality of diffusion regions separated by inactive regions. The cell also includes a gate electrode level including conductive features defined to extend in only a first parallel direction. Adjacent ones of the conductive features that share a common line of extent in the first parallel direction are fabricated from respective originating layout features that are separated from each other by an end-to-end spacing having a size that is substantially equal across the gate electrode level region and is minimized to an extent allowed by a semiconductor device manufacturing capability. The gate electrode level includes conductive features defined along at least four different virtual lines of extent in the first parallel direction. A width of the conductive features is less than a wavelength of light used in a photolithography process for their fabrication.
