摘要/描述

Abnormal grain growth in thin Cu films on Si substrates has been investigated as a function of annealing time. Abnormal grains with (110) orientation were observed by transmission electron microscopy. X-ray diffraction patterns showed that the films which underwent extensive abnormal grain growth also underwent a change in texture from (111) to (100), (110) and (311). A simple theoretical analysis showed that these were the results of a strain-energy-driven abnormal grain growth process.
