摘要:
In a surface treatment apparatus (30) of the face type, a porous dielectric (37) is supported by the outer periphery portion of the supporting member (45) under the bottom surface of a porous electrode (32). The dielectric can be supported by the supporting member to permit the thermal expansion deformation of the dielectric by forming an upward inclined-face (47) and a downward inclined-face (43) on the supporting member (45) and the dielectric (37), respectively. Further, a discharge gas can be supplied uniformly to a discharge region (51) through the electrode (32) and the dielectric (37), both of which are porous. Many gas exhaust ports (41), by which the flow rate of the gas can be regulated, are provided around the discharge region (51). Thus, the gas is uniformly exhausted around the discharge region (51). Especially, if the gap between the dielectric (37) and a work (39) depends on mounting accuracy or the like and varies with location, the gas can be exhausted uniformly around the discharge region (51).
摘要:
High frequency electrical discharge or nonpolar discharge using microwaves is generated in a gas that is introduced into a gas duct formed by a dielectric material, such as glass or ceramic. Surface treatment is applied to components, which are under atmospheric pressure, by exposing them to the gas flow containing the active species generated by the above mentioned electrical discharge. The components are soldered before, during, or after the application of this surface treatment. The surface of the components is exposed to the active species by either directly exposing the components to the electrical discharge, or by directing the reactive gas flow containing the active species at the component surfaces. By selecting an appropriate gas for generating the active species, it is possible to improve the wettability of the surface of the component to be soldered, or to remove organic substances or oxide film surfaces.

摘要:
A method for surface treatment of a substrate is described in which a gas discharge at or about atmospheric pressure produces activated gas or active species which are then used for surface treatment of a substrate. When the discharge gas contains oxygen, for example, surface treatment forms a metal oxide film on a metal circuit on a substrate. If, however, the gas contains hydrogen or an organic substance, a metal oxide film, such as a transparent electrode formed on the surface of a liquid crystal panel, is reduced. Alternatively, by causing discharge to take place adjacent to the surface of a liquid, or bubbled through a liquid, a liquid may be used for surface treatment of a substrate without risk of thermal or electrical damage to the substrate.

The present invention provides a joining, brazing or soldering material wherein solderability is effectively improved without using a flux, and a production method thereof. In production of a joining material, a halogen compound is mixed, a film is formed on the surface of a solder molding or the surface of a solder molding is halogenated. In production of a joining material, a halogen compound is added to a solder melt, a film of a halogen compound is formed on the surface of a processed joining material, or the surface layer of the processed joining material is converted to a halogen compound layer by halogenation. Film formation or surface treatment may be carried out either a dry or wet method.

A method and apparatus for solid bonding without using a bonding agent are provided. A surface of metal, glass, or other bond members 16a and 16b is fluorinated by exposure to a mixture of HF gas from a HF gas supply unit 24 and water vapor from a vapor generator 26 in a fluorination process section 12. The bond members 16a and 16b are then placed in contact at the fluorinated surface on table 36 in bonding process section 14. Argon is then introduced to bonding chamber 34. Pressure is then applied to the first bond member 16a and second bond member 16b by a cylinder 46, and heated to below the melting point by a heater 48, to bond the first and second bond members together.

A mask forming method that can reduce manufacturing cost is disclosed. The method forms a mask on the surface of a member to be processed in order to form a desired pattern using liquid material for patterning. The method also includes applying resist to the entire surface of the member to be processed, drying the applied resist, patterning by removing the resist in a pattern-formation area using photolithography, and heating the resist.

摘要:
Brazing or soldering materials which effectively improve the wettability of the brazing alloy or solder without using flux and a method of manufacturing such materials are provided. A metallic base is placed on turntable inside a vacuum chamber. A copper target is affixed to a sputtering electrode above the metallic base. Air is removed from the vacuum chamber through a vacuum outlet to increase the vacuum therein to a specific pressure, and carbon tetrafluoride and argon are introduced from a gas inlet to control the sputter pressure. Thereafter, turntable is rotated while a high frequency voltage is applied between the target and the metallic base to form a halide layer, such as a layer of copper fluoride, on a surface of metallic base.
