摘要	Interfacial reactions between eutectic SnIn and single crystalline Cu during solid-state aging at low temperature were investigated systematically. Three types of phase transformations between Cu(In,Sn)(2) layer and Cu-2(In,Sn) layer were observed, which are Cu(In,Sn)(2) grows and Cu-2(In,Sn) consumes at 40 degrees C, Cu(In, Sn)(2) and Cu-2(In,Sn) grow simultaneously at 60 degrees C, as well as Cu(In,Sn)(2) consumes and Cu-2(In, Sn) grows at 80 and 100 degrees C. According to physicochemical approach, the chemical reactions at Cu/Cu-2(In,Sn)/Cu(In,Sn)(2)/SnIn interfaces were discussed in detail. It was concluded that the diffusion ability of Cu and In atoms dominated different phase transformations. When diffusion constants k(1In2) > 8/3k(1Cu2) Cu(In,Sn)(2) will grow, and if k(1Cu2) >> k(1In2) Cu-2(In,Sn) will grow. Both Cu(In,Sn)(2) and Cu-2(In,Sn) can grow in the condition of k(1In2) approximate to k(1Cu2). The values of k(1Cu2) and k(1In2) at different temperatures on (100)Cu and (111)Cu substrate were also calculated or estimated by analyzing the growth kinetics of the compound layers.
