    Abstract: A fabrication method for a damascene bit line contact plug. A semiconductor substrate has a first gate conductive structure, a second gate conductive structure and a source/drain region formed therebetween. A first conductive layer is formed in a space between the first gate conductive structure and the second gate conductive structure to be electrically connected to the source/drain region. An inter-layer dielectric with a planarized surface is formed to cover the first conductive layer, the first gate conductive structure, and the second gate conductive structure. A bit line contact hole is formed in the inter-layer dielectric to expose the top of the first conductive layer. A second conductive layer is formed in the bit line contact hole, in which the combination of the second conductive layer and the first conductive layer serves as a damascene bit line contact plug.

    Abstract: A method for fabricating interconnects is provided. The method comprises forming a conducting line on a first dielectric layer; forming a first liner layer on the surfaces of the first dielectric layer and the conducting line; forming a second liner layer on the first liner layer; forming a second dielectric layer on the second liner layer, wherein the etching selectivity rate of the second dielectric layer is higher than the etching selectivity rate of the second liner; and patterning the second dielectric layer to form a contact window opening through the second liner layer and the first liner layer to expose the surface of the conducting line. Because the second dielectric layer having an etching rate higher than the etching rate of the second liner layer, the second liner layer can be used as an etch stop layer while patterning the second dielectric layer.

    Abstract: A method of forming interconnects. An oxide masking layer with patterns is formed overlaying the metal layer. The patterns of the masking layer are transferred into the metal layer so as to form an opening. Then, a silicon nitride liner is conformally formed on the masking layer, the metal layer and the first insulating layer. Next, the silicon nitride liner and the masking layer are partially removed by reactive ion etching to leave a facet mask to reduce the aspect ratio of the opening followed by removal of the remaining silicon nitride liner. Then, an insulating layer is deposited to fill the opening.

    Abstract: This invention relates to a method of fabricating metal wiring, whereby sputtered metal is rapidly cooled down by a post-metal quenching process, to prevent deleterious CuAl2 precipitation. The main embodiments are the formation of a TiN reactively sputtered bottom barrier layer, followed by a sputtered Al—Cu alloy wiring layer immediately followed by an in situ post-metal quench (key step), then followed by a reactively sputtered second TiN top barrier layer. The “in situ” post-metal quench is especially effective by employing wafer backside cooling using low temperature helium gas or argon gas, cooling the substrate from a high temperature range of 450 to 150 °C., to a low temperature range near room temperature, in a short time interval of between 30 to 180 seconds. The CuAl2 precipitates if allowed to form, block the etch removal of the underlying TiN layer causing electrical shorts between closely spaced lines.
