Imc gold boundaries
Witryna1 lis 2009 · In the interdiffusion of gold and indium for solid–solid state reactions at room temperature, four different IMCs of Au–In were reported to form as AuIn 2, AuIn, Au 7 In 3, and Au 4 In [].However, several researches have reported that when annealing temperature ranging from 200 to 300 °C was applied, only AuIn 2 was formed in the … WitrynaThe observed total IMC thickness and time relationships at 70, 100 and 150 oC, are shown in Figures 2 (a), (b), and (c). They all obey the predicted parabolic relationship. The slopes of the lines in Figure 2 indicate the rate of IMC growth. As expected, as the temperature increased, the rate of IMC layer growth increased. At all three
