  • Patent number: 11916038
    Abstract: Substrates that are bonding targets are bonded in ambient atmosphere via bonding films, including oxides, formed on bonding faces of the substrates. The bonding films, which are metal or semiconductor thin films formed by vacuum film deposition and at least the surfaces of which are oxidized, are formed into the respective smooth faces of two substrates having the smooth faces that serve as the bonding faces. The bonding films are exposed to a space that contains moisture, and the two substrates are overlapped in the ambient atmosphere such that the surfaces of the bonding films are made to be hydrophilic and the surfaces of the bonding films contact one another. Through this, a chemical bond is generated at the bonded interface, and thereby the two substrates are bonded together in the ambient atmosphere. The bonding strength ? can be improved by heating the bonded substrates at a temperature.
