Abstract(in English) | In Si-ULSI metallization technology, the growth of a Cu(111) preferentially oriented film is an important factor in the improvement of the electromigration reliability. We examined the application of a randomly oriented ZrN film with an extremely N-rich composition as a diffusion barrier, on which a highly oriented Cu(111) film will be obtained. This is because the good lattice matching between the ZrN(111) and Cu(111) planes is obtained by expanding the ZrN lattice due to incorporating the excess nitrogen atoms into the ZrN film. It is revealed that the Cu(111) preferred orientation (ω-FWHM value of ~5°) is realized on the randomly oriented ZrN barrier with good barrier properties. |
