    摘要: A method to achieve a very low effective dielectric constant in high performance back end of the line chip interconnect wiring and the resulting multilayer structure are disclosed. The process involves fabricating the multilayer interconnect wiring structure by methods and materials currently known in the state of the art of semiconductor processing; removing the intralevel dielectric between the adjacent metal features by a suitable etching process; applying a thin passivation coating over the exposed etched structure; annealing the etched structure to remove plasma damage; laminating an insulating cover layer to the top surface of the passivated metal features; optionally depositing an insulating environmental barrier layer on top of the cover layer; etching vias in the environmental barrier layer, cover layer and the thin passivation layer for terminal pad contacts; and completing the device by fabricating terminal input/output pads. The method obviates issues such as processability and thermal stability associated with low dielectric constant materials by avoiding their use. Since air, which has the lowest dielectric constant, is used as the intralevel dielectric the structure created by this method would possess a very low capacitance and hence fast propagation speeds. Such structure is ideally suitable for high density interconnects required in high performance microelectronic device chips.

    摘要: The present invention relates to a method of reactive sputtering for depositing an amorphous hydrogenated carbon film (a-C:H) from an argon/hydrocarbon/hydrogen/oxygen plasma, preferably an Ar/acetylene-helium/hydrogen/oxygen plasma. Such films are optically transparent in the visible range and partially absorbing at ultraviolet (UV) and deep UV (DUV) wavelengths, in particular, 365, and 248, 193 nm. Moreover, the films produced by the present invention are amorphous, hard, scratch resistant, and etchable by excimer laser ablation or by oxygen reactive ion etch process. Because of these unique properties, these films can be used to form a patterned absorber for UV and DUV single layer attenuated phase shift masks. Film absorption can also be increased such that these films can be used to fabricate conventional photolithographic shadow masks.

    摘要: Within a method for forming a metal-silicon layer there is first provided a reactor chamber. There is then positioned within the reactor chamber a substrate spaced from a metal source target. There is also provided within the reactor chamber a minimum of a sputter material and a reactive silicon material. There is then sputtered the metal source target positioned within the reactor chamber with the sputter material provided within the reactor chamber in the presence of the reactive silicon material provided within the reactor chamber to form a metal-silicon layer over the substrate. The method is particularly useful for forming metal silicate layers, metal silicon nitride layers and metal silicon oxynitride layers within microelectronic fabrications. An alternative method employs: (1) a silicon source target rather than a metal source target; and (2) a reactive metal material rather than a reactive silicon material.
