US Patent 10090325 Circuit cells having separated gate electrodes

A device includes first circuit cells. Each of the first circuit cells includes isolation transistors, a first type transistor, a second type transistor, and a first gate contact. The isolation transistors are arranged adjacent to another one circuit cell of the plurality of first circuit cells. The first type transistor includes a first gate electrode. The second type transistor includes a second gate electrode, in which the second gate electrode is disposed with respect to the first gate electrode. The first gate contact is coupled between the first gate electrode and the second gate electrode.
