Semiconductor device and associated layouts including linear conductive segments having non-gate extension portions

摘要

A restricted layout region in a layout of a semiconductor device is disclosed to include a diffusion level layout including a plurality of diffusion region layout shapes. The plurality of diffusion region layout shapes are defined in a non-symmetrical manner relative to a centerline defined to bisect the diffusion level layout. A gate electrode level layout is defined to include a number of linear-shaped layout features placed to extend in only a first parallel direction. Each of the number of the linear-shaped layout features within the gate electrode level layout of the restricted layout region is rectangular-shaped. The gate electrode level layout includes linear-shaped layout features defined along at least four different lines of extent in the first parallel direction. Each of a number of interconnect level layouts is defined to pattern conductive features within corresponding interconnect levels above the gate electrode level.
