Abstract
Theoretical aspects of kinetics and transport phenomena during the hillocks formation and growth in thin Al films are discussed. Following the suggested methodology, the conceptual relationship of step by step linear and/or parabolic law for hillock volume changes ΔV with time t:(where n = 1 and/or ½; K is the changeable coefficient and (i) is the appropriate time sequence) is proposed.Finally, using the experimental measurements from S. J. Hwang, Y. D. Lee, Y. B. Park, J. H. Lee, C. O. Jeong, and Y. C. Joo: Scripta Mater., 2006, 54, 1841–1846, illustrative calculation results of the proposed concept are presented.
