Layout of Cell of Semiconductor Device Having Rectangular Shaped Gate Electrode Layout Features Defined Along At Least Four Gate Electrode Tracks with Corresponding p-type and n-type Diffusion Regions Separated by Central Inactive Region

摘要

A layout of a cell of a semiconductor device is disclosed to include a diffusion level layout including a plurality of diffusion region layout shapes to be formed within a portion of a substrate, including a p-type diffusion region layout shape and an n-type diffusion region layout shape separated by a central inactive region. The layout of the cell also includes a gate electrode level layout 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. The gate electrode level layout corresponds to an entire gate electrode level of the cell.
