    摘要: A structure and method of fabrication of a semiconductor integrated circuit is described. A first patterned electrically conductive layer contains a low dielectric constant first insulating material such as organic polymer within the trenches of the pattern. A second insulating material such as a silicon dioxide or other insulating material having a greater. mechanical strength and thermal conductivity and a higher dielectric constant than the first insulating material is formed over the first patterned electrically conductive layer Vias within the second insulating material filled with electrically conductive plugs and a second patterned electrically conductive layer may be formed on the second insulating material. The structure can be repeated as many times as needed to form a completed integrated circuit.

    摘要: An interconnect structure for microelectronic devices includes a plurality of patterned, spaced apart, substantially co-planar, conductive lines, a first portion of the plurality of conductive lines having a first intralayer dielectric of a first dielectric constant therebetween, and a second portion of the plurality of conductive lines having a second intralayer dielectric of a second dielectric constant therebetween. By providing in-plane selectability of dielectric constant, in-plane decoupling capacitance, as between power supply nodes, can be increased, while in-plane parasitic capacitance between signal lines can be reduced.

    摘要: A device and methods of forming an interconnection within a prepatterned channel in a semiconductor device are described. The present invention includes a method of forming an interconnect channel within a semiconductor device. A first dielectric layer is deposited over a substrate and patterned to form a contact opening that is subsequently filled with a contact plug. A second dielectric layer is deposited over the patterned first dielectric layer and the contact plug. The second dielectric layer is patterned to form the interconnect channel, wherein the first dielectric layer acts as an etch stop to prevent etching of the substrate. The present invention also includes a method of forming an interconnect. A dielectric layer is deposited over a substrate and patterned to form an interconnect chapel. A metal layer is deposited over the patterned dielectric layer and within the interconnect channel. The metal layer is polished with an alkaline solution to remove the metal layer that does not lie within the interconnect chapel to form an interconnect. The present invention further includes a method of forming an interconnect over a silicon nitride layer. The silicon nitride layer is deposited over a semiconductor substrate and patterned to form a contact opening that is subsequently filled with a conductive material. A metal layer is deposited on the patterned silicon nitride layer and the contact plug and patterned to form the interconnect such that all of the interconnect lies on the contact plug and part of the patterned silicon nitride layer.
