In this paper, the growth process of aluminum on a silicon substrate by metalorganic molecular beam epitaxy using dimethyl-ethylamine alane has been described. The crystallographic orientation of the aluminum grains strongly depends on the substrate temperature. The epitaxial single crystalline (111) Al grains grow on a (111) Si substrate at a substrate temperature between 450 and 500°C. The bi-crystalline (110) Al grains grow on a (100) Si substrate at the substrate temperature between 350 and 450°C. For a (100) Si substrate, the orientation of Al is related to the reconstruction of the Si substrate. Furthermore, the selective growth of Al into 1.5-µm-diameter via-holes is shown to be possible.
