发明名称 Guard rings on fin structures
摘要 A device includes a semiconductor substrate, isolation regions extending into the semiconductor substrate, a plurality of semiconductor fins higher than top surfaces of the isolation regions, and a plurality of gate stacks. Each of the gate stacks includes a gate dielectric on a top surface and sidewalls of one of the plurality of semiconductor fin, and a gate electrode over the gate dielectric. The device further includes a plurality of semiconductor regions, each disposed between and contacting two neighboring ones of the plurality of semiconductor fins. The device further includes a plurality of contact plugs, each overlying and electrically coupled to one of the plurality of semiconductor regions. An electrical connection electrically interconnects the plurality of semiconductor regions and the gate electrodes of the plurality of gate stacks.
