Abstract:
Reliability of a plating process and reliability of a component manufactured through the plating process can be improved by suppressing peeling between plating layers formed by electroless plating. In a plating method, a plated component manufactured by the plating method, and a plating system 1 configured to manufacture the plated component by the plating method, a second electroless plating layer 39, which is made of a copper alloy and formed by the electroless plating, is formed on a surface of a first electroless plating layer 38 formed by the electroless plating. The first electroless plating layer 38 is a barrier layer configured to suppress diffusion of copper and is made of cobalt or a cobalt alloy. The second electroless plating layer 39 is a seed layer for forming an electrolytic plating layer of copper on a surface thereof and is made of an alloy of copper and nickel.
Abstract:
An electroless plating process is performed on an Al layer, which is made of aluminum or an aluminum alloy, with an electroless plating liquid which is alkaline and contains a complexing agent. A plating method includes preparing a substrate 10 having a surface (for example, bottom surface of TSV 12) at which an Al layer 22 made of aluminum or an aluminum alloy is exposed; forming a zincate film 30 on a surface of the Al layer by performing a zincate treatment on the substrate; and forming a first electroless plating layer (for example, Co barrier layer 14a) on the surface of the Al layer with an electroless plating liquid (for example, Co-based plating liquid) which is alkaline and contains a complexing agent.

A plating apparatus 20 includes a substrate holding device 110 configured to hold a substrate W; a discharging device 21 configured to discharge a plating liquid 35 toward the substrate W held by the substrate holding device 110; and a plating liquid supplying device 30 connected to the discharging device 21 and configured to supply the plating liquid 35 to the discharging device 21. A gas supplying device 170 is configured to heat a heating gas G having a higher specific heat capacity than air and supply the heated heating gas G toward the substrate W held by the substrate holding device 110. Further, a controller 160 is configured to control at least the discharging device 21, the plating liquid supplying device 30, and the gas supplying device 170.
Abstract:
Adhesivity between a catalyst adsorption layer on a substrate and a barrier metal plating layer can be improved. The catalyst adsorption layer 22 containing a catalyst metal is formed on the substrate 2 by supplying a catalyst solution onto the substrate 2, and a bonding metal layer 22A containing a bonding metal different from the catalyst metal is formed on the catalyst adsorption layer 22 by performing a plating process with the catalyst metal as a catalyst. A barrier metal plating layer 23 is formed on the bonding metal layer 22A by performing a plating process with the bonding metal as a catalyst.

Abstract:
A plating method can improve adhesivity with a substrate. The plating method of performing a plating process on the substrate includes forming a vacuum-deposited layer 2A on the substrate 2 by performing a vacuum deposition process on the substrate 2; forming an adhesion layer 21 and a catalyst adsorption layer 22 on the vacuum-deposited layer 2A of the substrate 2; and forming a plating layer stacked body 23 having a first plating layer 23a and a second plating layer 23b which function as a barrier film on the catalyst adsorption layer 22 of the substrate 2. By forming the vacuum-deposited layer 2A, a surface of the substrate 2 can be smoothened, so that the vacuum-deposited layer 2A serving as an underlying layer can improve the adhesivity.
