- a pump for pumping the supplied humidified air, a valve for controlling the discharge of the humidified air (neither of them is shown), and the like are provided. May be good. Further, in this example, the spraying area of the spray nozzle 26 cannot cover all of one or more objects 130 supported by the support base 22.

- the saturated water vapor pressure at this temperature Ta is Ha. If air having a water vapor pressure exceeding the saturated water vapor pressure Ha comes into contact with the joint surface, dew condensation will occur on the joint surface. Therefore, the humidified air may have a water vapor pressure equal to or higher than the saturated water vapor pressure Ha at the ambient temperature Ta (that is, the temperature of the joint surface).
- the humidity of the surrounding atmosphere is sufficiently low, and the dew condensation evaporates.
- OH groups remain attached to the surface of the joint surface even if the droplets evaporate thereafter. In other words, according to the method, an appropriate amount of OH groups can be easily attached to the joint surface, while the residual droplets can be effectively prevented.

- the conditions of the humidified air when the object 130 is cooled by the cooler 24 will be described with reference to FIG.
- the object 130 When cooling the object 130, it is necessary to suppress the cooling temperature to a temperature at which dew condensation does not occur in the surrounding atmosphere. Specifically, when the temperature of the surrounding atmosphere is Ta and the humidity is Aa%, the water vapor pressure contained in the surrounding atmosphere is Hc. Since the dew point of the water vapor pressure Hc is Tc, dew condensation occurs in the surrounding atmosphere at a temperature of Tc or less. Therefore, when cooling the object 130, the joint surface temperature must exceed the dew point of the water vapor pressure contained in the surrounding atmosphere, or Tc in the example of FIG.
- the surface temperature of the frame member is the same as the temperature Ta of the surrounding atmosphere.
- the humidity difference may be utilized to cause dew condensation only on the joint surface of the cooled object 130 and not to cause dew condensation on the surface of the uncooled frame member.

That is, in the example of FIG. 7, if the joint surface of the object 130 is cooled to the dew point temperature Tc or less of the water vapor pressure Hc in the surrounding atmosphere, dew condensation occurs on the joint surface without blowing humidified air. However, it takes some time to raise the once cooled object 130 to a temperature at which dew condensation evaporates. Therefore, when the object 130 is cooled to cause dew condensation, the dew condensation continues until the object 130 rises to a temperature at which the object 130 can evaporate, and a large amount of droplets are generated on the joint surface.
- the spray nozzle 26 since the spraying area of the spray nozzle 26 is smaller than the total area of the plurality of objects 130 mounted on the support base 22, the spray nozzle 26 is moved and scanned.
- the configuration of such a spray nozzle 26 may be changed as appropriate.
- the spray nozzle 26 may have a spray area that can cover all of the plurality of objects 130.
- a plurality of spray holes 26a provided in the spray nozzle 26 may be provided. With such a configuration, humidified air can be more reliably and evenly dispersed.

- the configuration of the spray nozzle 26 can be simplified. Further, the humidified air may be blown in a columnar shape as shown in FIG. 9 (b), or may be blown in a conical shape as the diameter increases as it goes downstream, as shown in FIG. 9 (c).
- the chip 110 is conveyed from the chip supply unit 12 to the first surface treatment device 20f (S10).
- the chip 110 is carried into the first surface treatment device 20f in a state of being adhered to the dicing tape 120 stretched inside the dicing ring 122.

- the hydrophilic treatment of the wafer 100 is also performed. That is, the wafer 100 that functions as a substrate is conveyed from the substrate supply unit 14 to the second surface treatment device 20s (S14). Subsequently, the transferred wafer 100 is subjected to a hydrophilization treatment (S16). Specifically, in a state where the wafer 100 is placed on the support base 22, the wafer 100 is cooled and humidified air is blown to the joint surface of the wafer 100 by the spray nozzle 26.
- the chip 110 is temporarily bonded to the wafer 100 by hydrogen bonding (S18).
- the hydrophilized wafer 100 is conveyed to the bonding unit 16 and placed on a table provided in the bonding unit 16. Further, the bonding tool provided in the bonding unit 16 sucks and holds the hydrophilized chip 110 and places it on the upper surface of the wafer 100.
- the bonding surfaces of the chip 110 and the wafer 100 come into contact with each other, the OH groups attached to both bonding surfaces form hydrogen bonds. As a result, the chip 110 and the wafer 100 are temporarily joined with a certain degree of joining force.
- the temporarily bonded wafer 100 and the chip 110 are subsequently heated, and the two are finally bonded (S20).
- S20 By heating the chip 110 and the wafer 100, water molecules at the bonding interface evaporate, and the Si atoms of both are firmly bonded to each other. So to speak, the silicon of the chip 110 and the silicon of the wafer 100 are atomically bonded. This provides a strong bond.
- the production of the semiconductor device is completed.
- the chips 110 are not laminated
- two or more chips 110 may be laminated in the thickness direction.
- the upper surface of the chip 110 located on the lower side serves as a joining surface with other chips 110 laminated on the upper side thereof, but the upper surface of the lower chip 110 may be hydrophilized. It does not have to be.
- the upper surface of the lower chip 110 is hydrophilized, for example, after the lower chip 110 is placed on the wafer 100, the lower chip 110 is placed on the surface treatment device 20 again together with the wafer 100. , Just put it in.
- the configuration described so far is an example, in which the surface treatment device 20 has at least a support base 22 that supports a surface of the object 130 on the side opposite to the joint surface, and the joint surface at the temperature of the joint surface.
- Other configurations may be appropriately modified as long as it has a spray nozzle for blowing humidified air having a water vapor pressure equal to or higher than the corresponding saturated water vapor pressure.
- both the chip 110 and the wafer 100 are hydrophilized, but the hydrophilization treatment may be applied only to at least one of the chip 110 and the wafer 100. Therefore, the manufacturing apparatus 10 may have only one of the first surface treatment apparatus 20f and the second surface treatment apparatus 20s, and may not have the other. Further, in this example, the object 130 is cooled in the hydrophilization treatment, but the object 130 does not have to be cooled.
- the hydrophilization treatment is performed on the joint surface, but prior to the hydrophilization treatment, another surface treatment, for example, irradiating the joint surface with plasma to activate the atoms on the joint surface.
- Plasma treatment may be performed.
- the surface treatment device 20 is incorporated in the manufacturing device 10 of the semiconductor device, but the surface treatment device 20 may be incorporated in another device for joining the object 130 by utilizing hydrogen bonds. .. Further, the surface treatment device 20 may be used alone without being incorporated in another device.
