Abstract: A bonding method using a bonding agent is provided, which has the steps of forming an underlayer on a first member, providing a bonding agent on the underlayer, forming a contact member, different from the bonding agent, on a second member, bringing the bonding agent into contact with the contact member so that the first member and the second member are bonded to each other. In the method described above, the wettability of the bonding agent to the underlayer is superior to that of the bonding agent to a surface of the first member before the underlayer is formed thereon, and the bondability of the bonding agent to the contact member is superior to that of the bonding agent to a surface of the second member before the contact member is formed thereon.

Abstract: A joining material like an In film having a low melting point forms a surface oxide film when melted. If the oxide film is thick, an uneven surface shape will remain as it is, and can cause vacuum leakage during vacuum sealing. This problem is solved, for example, by placing particles of a refractory material inside the low melting joining material. The particles of the refractory material serve as a holding member for the low melting material and break the oxide film during a joining operation to bring the seal bonding with the low melting material to perfection.

Abstract: In a manufacturing method of forming a hermetically sealed container by bringing a pair of substrates into intimate contact via a supporting frame between them, one of the substrates is warped in a depressurized atmosphere before getting into intimate contact and is thereby separated from the other substrate so as to evacuate inside of the hermetically sealed container by releasing the depressurized atmosphere therein. Relative positions of the substrates are restored by having the warp undone thereafter. Therefore, it is possible to achieve evacuation inside the hermetically sealed container without causing the relative positions of the substrates to deviate.

Abstract: An electron-emitting device having an electroconductive film including an electron-emitting region arranged between a pair of device electrodes is manufactured. The electroconductive film is formed by applying a liquid containing the material of the film to a substrate by using an ink-jet method, then drying and heating the applied liquid. Defective conditions, if any, in the applied liquid or the precursor film formed by drying the liquid or the electroconductive film formed by heating the precursor film are detected and remedied by applying the same liquid again to the area detected for a defective condition. The detection and remedy of any defective condition may be conducted after the liquid-applying, drying or baking step.
