An integrated circuit product includes a first layer of insulating material above a device layer of a semiconductor substrate and with a lowermost surface above an uppermost surface of a gate of a transistor in a device layer of the semiconductor substrate. A metallization blocking structure is in an opening in the first layer of insulating material and has a lowermost surface above the uppermost surface of the gate and includes a second insulating material that is different from the first insulating material. A metallization trench is in the first layer of insulating material on opposite sides of the metallization blocking structure. A contact structure is in the second insulating material and entirely below the metallization trench. A conductive metallization line includes first and second portions positioned in the metallization trench on opposite sides of the metallization blocking structure and a long axis extending along the first and second portions.
