    摘要: A method for forming interconnections for semiconductor fabrication and semiconductor devices have such interconnections are described. A first patterned dielectric layer is formed over a semiconductor substrate and has a first opening filled with conductive material. Another patterned dielectric layer is formed over the first dielectric layer and has a second opening over at least a portion of the conductive material. The first patterned dielectric layer may serve as an etch-stop in patterning the other patterned dielectric layer. Also, a dielectric etch-stop layer may be formed over the first patterned dielectric layer and over the conductive material before the other patterned dielectric layer has been formed. This dielectric etch-stop layer may serve as an etch-stop in patterning the other patterned dielectric layer. The second opening exposes a portion of the dielectric etch-stop layer. The exposed portion of the dielectric etch-stop layer is removed. The second opening is filled with conductive material.

    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.

    摘要: Silicon-rich silicides of titanium and tantalum have been found to be suitable for use as the gate metal in semiconductor integrated circuits replacing polysilicon altogether. Such silicon-rich silicides, formed by sintering a cosputtered alloy with silicon to metal ratio of three as in deposited film, are stable even on gate oxide. The use of these compounds leads to stable, low resistivity gates and eliminates the need for the high resistivity polysilicon gate.

    摘要: An interconnect structure for microelectronic devices indudes 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.
