Efficient semiconductor device cell layout utilizing underlying local connective features
摘要:
Provided are semiconductor device cells, methods for forming the semiconductor device cells and a layout style for the semiconductor device cells. The device cells may be repetitive cells used throughout an integrated circuit. The layout style utilizes an area at the polysilicon level that is void of polysilicon and which can accommodate conductive leads therein or thereover. The conductive leads are formed of material typically used for contacts or vias and are disposed beneath the first metal interconnect level which couples device cells to one another. The subjacent local conductive leads may form subjacent signal lines allowing for additional power mesh lines to be included within the limited number of metal tracks that can be accommodated within a device cell and in accordance with metal track design spacing rules.
