A substrate on which a plurality of gate structures is formed is provided, wherein the gate structure comprises a gate, a gate capping layer, and a gate spacer. An insulating layer is formed on the gate structures and fills between the gate structures. The insulating layer is etched using the gate capping layers, the gate spacers, and the substrate as stop layers to form first contact holes between the gate structures to expose the substrate and the gate spacers and form second contact holes overlying each gate structure to expose the gate capping layers. A protective spacer is formed over each sidewall of the first contact holes and the second contact holes. The gate capping layer under each gate contact hole is etched using the protective spacer as a stop layer to expose the gate. The protective spacers are removed.

    摘要: 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.

    摘要: A method of forming a metal plug. First, a dielectric layer is formed on a substrate. Next, a patterned hard mask is formed on the dielectric layer. The dielectric layer is etched through the patterned hard mask to form a contact hole in the dielectric layer so as to expose parts of the substrate. An isolated layer is formed on the patterned hard mask. A barrier is then formed conformally on the isolated layer and the exposed substrate of the contact hole. A metal layer is formed to fill the contact hole and cover the barrier. A thermal treatment is performed to form a silicide between the barrier layer and the substrate. Finally, parts of the metal layer, barrier, isolated layer, and patterned hard mask are removed. The metal plug with a planar surface is thus formed in the contact hole.
