Cell architecture and method

摘要

A method includes selecting a cell stored in a non-transient computer readable storage medium, arranging a plurality of the cells on a model of a semiconductor device, and creating a mask for the semiconductor device based on the model of the semiconductor device. The cell is designed according to a design rule in which a first power-supply-connection via satisfies a criterion from the group consisting of: i) the first power-supply-connection via is spaced apart from a second power-supply-connection via by a distance that is greater than a threshold distance such that the cell can be fabricated by a single-photolithography single-etch process, or ii) the first power-supply-connection via is coupled to first and second substantially parallel conductive lines that extend along directly adjacent tracks.
