Abstract: Methods of forming capping structures on one or more different material surfaces are provided. One embodiment includes disposing a semiconductor structure in a reduced pressure chamber, forming a capping GCIB within the reduced pressure chamber, and directing the capping GCIB onto at least one of the one or more different material surfaces, so as to form at least one capping structure on the one or more surfaces onto which the capping GCIB is directed.

Abstract: Capping layer or layers on a surface of a copper interconnect wiring layer for use in interconnect structures for integrated circuits and methods and apparatus for forming improved integration interconnection structures for integrated circuits by the application of gas-cluster ion-beam processing. Reduced copper diffusion and improved electromigration lifetime result and the use of selective metal capping techniques and their attendant yield problems are avoided. Various cluster tool configurations including gas-cluster ion-beam processing modules for copper capping, cleaning, etching, and film formation steps are disclosed.

Abstract: Various alignment targets are disclosed having improved visibility. A first embodiment includes an alignment target having a first reflective layer of a first material such as tungsten having a roughened surface; and a second layer of a second material, such as aluminum, deposited on the first layer. The surface of the second layer is roughened by conforming with the roughened surface of the first layer to provide both layers with a uniform optical layers. The edges of the second layer provides an optical signal to contrast between the two layers for alignment. A second embodiment includes an alignment target with a plurality of parallel elongated trenches; a first material fills each of the trenches; and a patterned layer of a second material is deposited on top the elongated trenches and the insulator layer.

Abstract: The preferred embodiment of the present invention provides a structure and method for personalizing a semiconductor device in the context of a bump array connection to packaging, substrates and such. The preferred embodiment method uses a plurality of conduction lines on said semiconductor device, including a plurality of landing lines and personalization lines. Vias are opened to the plurality of landing lines and selectively opened to a portion of the personalization lines. Connections are made between the opened personalization lines with bumps deposited as part of the bump array.

Abstract: A metallization composite comprises a refractory metal, nickel, and copper. The refractory metal is preferably titanium (Ti), but other suitable refractory metals such as zirconium and hafnium can also be utilized. An additional optional layer of gold can overlie the copper. The metallization composite is used to connect a solder contact to a semiconductor substrate.
