Site location analysis of Au dopants in Cu6Sn5 intermetallic compound by Cs-corrected STEM

Wenhui Yang1, Tomokazu Yamamoto1, Kazuhiro Nogita2, Syo Matsumura1 1 Department of Applied Quantum Physics and Nuclear Engineering, Kyushu University, 2 Nihon Superior Centre for the Manufacture of Electronic Materials (NS CMEM), School of Mechanical and Mining Engineering, The University of Queensland

Cu6Sn5 is an important intermetallic compound in soldering and electronic packaging. It is formed at the interface between molten solder and substrate during the soldering process, and the evolution of microstructure and properties also occurs in service. Zeng et.al reveled that Au and Zn are stabilization alloying elements for hexagonal η-Cu6Sn5 intermetallic [1]. To understand of stabilization mechanisms at atom scale, in this work, we performed direct observation for dopants in Cu6Sn5 intermetallic codoped with Au and Ni elements using high-angle annular dark-field (HAADF) imaging and atomic-resolution chemical mapping with aberration-corrected (Cs-corrected) scanning transmission electron microscopy (STEM). It was found that Cu6Sn5 doped with Au and Ni has hexagonal structure. HAADF-STEM and atomic-resolution STEM-EDXS mapping reveled that Au atoms occupy the Cu1 sites in η-Cu6Sn5 although Ni dopant site location is still unclear. 1. G.
