- splash may occur when a SiO vapor deposition film is formed on a polymer film using this SiO vapor deposition material. This splash is a phenomenon in which fine particles of high temperature that are not sublimated are scattered together with the sublimated SiO gas, and when these fine particles adhere to the SiO vapor deposition film on the polymer film, defects such as pinholes are caused. This causes the gas barrier property to deteriorate.
- Patent Document 1 proposes a SiO vapor deposition material having a low hydrogen gas content.
- the same document shows the relationship between the hydrogen gas content in the SiO vapor deposition material and the number of splash occurrences, and it is said that the number of splash occurrences can be greatly reduced by setting the hydrogen gas content to 50 ppm or less. .
