  • Patent number: 10026726
    Abstract: Semiconductor devices and method of manufacturing such semiconductor devices are provided for improved FinFET memory cells to avoid electric short often happened between metal contacts of a bit cell, where the meal contacts are positioned next to a dummy gate of a neighboring dummy edge cell. In one embodiment, during the patterning of a gate layer on a substrate surface, an improved gate slot pattern is used to extend the lengths of one or more gate slots adjacent bit lines so as to pattern and sectionalize a dummy gate line disposed next to metal contacts of an active memory cell. In another embodiment, during the patterning of gate lines, the distances between one or more dummy gates lines disposed adjacent an active memory cell are adjusted such that their locations within dummy edge cells are shifted in position to be away from metal contacts of the active memory cell.
