Abstract:
A method includes forming a gate stack over a semiconductor fin, wherein the semiconductor fin forms a ring, and etching a portion of the semiconductor fin not covered by the gate stack to form a recess. The method further includes performing an epitaxy to grow an epitaxy semiconductor region from the recess, forming a first contact plug overlying and electrically coupled to the epitaxy semiconductor region, and forming a second contact plug, wherein the second contact plug is overlying and electrically coupled to the gate stack.

Claim (Index 1):
A device comprising:\n a semiconductor substrate; and a guard ring comprising:\n a first plurality of semiconductor fins aligned to a first ring, wherein the first ring encircles a portion of the semiconductor substrate; \n a plurality of gate stacks on sidewalls and top surfaces of the first plurality of semiconductor fins; \n a plurality of semiconductor regions, with each being between two of the first plurality of semiconductor fins; and \n a well region overlapped by the plurality of semiconductor regions and the first plurality of semiconductor fins, wherein the plurality of semiconductor regions and the well region are of a same conductivity type.
