A method of fabricating a node contact on a substrate, which contains a first conductive device and an insulating layer covering the substrate and the first conductive device, includes forming at least two conductive lines on the insulating layer, wherein the conductive lines are separated by a first distance; forming at least two second conductive devices on the insulating layer, wherein the second conductive devices are separated by a second distance, and wherein one of the conductive lines and one of the second conductive devices are separated by a third distance, and wherein both the first and second distances are greater than the third distance; forming an isolation layer of a thickness on the substrate to cover the insulating layer, the conductive lines and the second conductive devices, wherein the isolation layer comprises a dished area located between the second conductive devices; removing a portion of the isolation layer to form a spacer around the second conductive devices, and to deepen the dished area to form an opening exposing the insulating layer; deepening the opening to expose the first conductive device; and filling the opening with a conductive material.
