The growth of intermetallic phases in Al/Cu bilayers thin film having 2/3 layer thickness ratios were characterized by X-ray powder diffraction (XRD), energy dispersive X-ray (EDX) and transmission electron microscopy (TEM). In annealing temperature of 200 °C, the growth is controlled by Cu diffusion which resulted to formation of θ-Al2Cu, η-AlCu, ζ-Al3Cu4 and γ-Al4Cu9 phase.
