摘要:
Methods and devices for patterning electroless metals on a substrate are presented. An active catalyst layer on the substrate can be covered with a patterned mask and treated with a deactivating chemical reagent, which deactivates the catalyst layer not covered by the mask. Once the patterned mask is removed, the electroless metal layer can be placed to have a patterned electroless metals. Alternatively, a substrate can be coated with a blocking reagent in a pattern first to inhibit formation of the catalyst layer before a catalyst layer can be placed over the blocking agent layer and then electroless metal layer is placed on the catalyst layer. The pattern of the blocking reagent acts as a negative pattern of the final conductive line pattern.

Process for producing a metal layer on a substrate body. The process includes applying conductive particles to a surface of the substrate body, so that the conductive particles are fixed to the substrate body, and metallizing the substrate body together with the particles chemically and/or by electrodeposition in a metallization bath so as to form the metal layer.

A pre-treatment method of plating and a plating system can perform a uniform plating process in which sufficient adhesivity on a surface of a substrate is obtained. The pre-treatment method of plating includes a coupling layer forming process of forming a titanium-based coupling layer 21b on the surface of the substrate with a titanium coupling agent; and a coupling layer modification process of modifying a surface of the titanium-based coupling layer 21b with a modifying liquid after the coupling layer forming process.

Disclosed herein are various methods of filing voids in copper conductive structures on integrated circuit devices. In one example, the method includes the steps of forming a conductive copper structure in a layer of insulating material and performing an electroless deposition process to selectively form a fill layer comprised of a conductive material on the copper containing structure, the fill layer being adapted to at least partially fill any voids that may exist in the conductive copper structure.

Provided is a method of manufacturing a rotary machine, which includes: a casing forming process of forming a casing of the rotary machine that has multiple opening parts and suctions and discharges a fluid; a surface activating process of supplying a pretreatment liquid into the casing, then discharging the pretreatment liquid from the casing through the opening parts, and activating an inner surface of the casing after the casing forming process; a plating process of performing supply and discharge of a plating liquid into and from the easing through the opening parts to circulate the plating liquid and plating the inner surface of the casing after the surface activating process; and an assembling process of providing a rotating body that is rotatable relative to the casing so as to he covered from an outer circumference side by the casing plated in the plating process.

A method is for plating metal or alloy blanks. The method includes heating the metal or alloy blanks at a recrystallization temperature sufficient to soften the steel for minting; plating the softened metal or alloy blanks with one or more layers of metal or alloy; and heating the plated blanks at a temperature sufficient to reduce plating stresses but below the recrystallization temperature of the outermost plating layer.
