Aluminium–copper alloys ( AlCu) are aluminum alloys that consist largely of aluminum (Al) and traces of copper (Cu) as the main alloying elements. Important grades also contain additives of magnesium and silicon ( AlCu (Mg,Si) ), often manganese is also included to increase strength (see Aluminum-manganese alloys ).

The AlCu 3 intermetallic was anisotropic in nature and its formation must either be controlled or prevented. • The AlCu 3 intermetallic was much more cathodic when compared to AlCu with respect to Aluminum. The galvanic coupling created between the Al and AlCu was the main reason for obtaining higher corrosion resistance value.Using Pure Aluminium. Commercially, it would be assumed that a material having the lowest resistivity would be used for IC interconnections. This is because, the lower the resistivity of the material, the smaller the resultant RC-delay, and the faster the signal transmission between devices – in order to be useful, resistivities must be below …

Using the optimum Ti …AlCu x NiTiZr 0.75 high entropy alloy (HEA) films were deposited by magnetron sputtering with an alloy target in combination with a pure Cu metal target. The purpose of this study was to reduce electrical resistivity of the HEA films while maintaining mechanical properties and corrosion resistance by adjusting Cu content of the HEA. We …The last one with composition of AlCu is known to exist in two stable forms: the high temperature phase η 1 (oS32) [14] stable between 847 and 898 K, and the low temperature phase η 2 (C2/m) [22] stable below 854 K. For simplicity, no separation of those phases was considered and hence those phases were modeled as γ, ε, ζ and η in this work.AlCu hot sputter/reflow and high-pressure fill are some of the physical vapor deposition (PVD)-based techniques that have been investigated to fill high-aspect ratio vias 2, 3. However, temperatures in excess of 450°C are typically required and these processes suffer from inconsistent void-free fill of sub-0.25 ...

The electromigration (EM) characteristics of super-thin aluminum-copper alloy (AlCu) interconnects for sub-0.13 μm complementary metal-oxide-semiconductor logic technology were investigated by varying the AlCu underlayers and etched sidewall profile of AlCu wire. Super-thin AlCu wire with a Ti/TiN underlayer and a smooth etched sidewall …

For the AlCu/TiN/Ti structure, on the other hand, the line resistance increased during the EM tests and TEM observation confirmed that the amount of Al 3 Ti compound was very small and it did not form a continuous layer. These results indicated that the above mechanism hardly contributes to the EM. Consequently, the EM of the AlCu/TiN/Ti ...

Results suggest that AlCu and Al 4 Cu 9 are energetically more favorable than Al 2 Cu, which is consistent with the observed IMC forming sequence from Al 2 Cu to AlCu or Al 4 Cu 9 [38], [39]. The formation energy of AlCu is compatible with but slightly lower than that of Al 4 Cu 9, indicating that AlCu tends to be the most stable phase among ...Obtained by using KoBo deformation, microstructures of AlCu alloys are connected with ultrafine near-equiaxed grains of α-Al and Al 2 Cu phase.
