From this graph, it can be seen that the vapor pressure of WO 3 is larger than the vapor pressure of Au, and the vapor pressure of WO 2 is close to the vapor pressure of Au. Therefore, WO 2 and WO 3 are contained in the melt of the Au base material. If it is done, it is clear that bumping easily occurs.

- Table 8 shows the number of splashes when a metal evaporation material using Ti as an additive metal is placed in a refractory metal container 22 made of W and melted.
- Ti has a smaller number of splashes than Ta and Zr, but as shown in Table 9, the resistivity of the Au thin film obtained from the metal evaporation material containing Ti as an additive metal is that of the additive-free Au base material. Since the resistivity of the Au thin film obtained from the metal evaporation material is higher than that of Ti, the Au thin film is considered to contain Ti at a high concentration.
- the resistivity is about the same as the resistivity of an Au thin film obtained from a metal evaporation material made of an additive-free Au base material. It can be seen that the additive metal is not contained.
- the base material is not limited to a single metal and may be an alloy.
