摘要:
Embodiments of the present invention provide methods for fabricating a semiconductor device with buried local interconnects. One method may include providing a semiconductor substrate with fins etched into the semiconductor substrate; forming a first set of spacers along the sides of the fins; depositing a tungsten film over the top surface of the substrate; etching the tungsten film to form a buried local interconnect; forming a set of gates and a second set of spacers; forming a source and drain region adjacent to the fins; depositing a first insulating material over the top surface of the substrate; and creating contact between the set of gates and the source and drain region using an upper buried local interconnect.
