Abstract
A coated substrate includes a substrate, a zirconium-containing layer disposed over the substrate, and one or more copper alloy layers disposed over the substrate. Variations include coated substrate with a single copper alloy layer, alternating copper layers, or a combined copper alloy/zirconium-containing layer.
Claims28
A coated substrate comprising:
- a substrate;
- a zirconium-containing base layer disposed over the substrate, the zirconium-containing base layer being a zirconium carbonitride base layer or a zirconium nitride base layer wherein the zirconium-containing base layer includes a compound having formula:
- Zr1-x-yCxNy,
- where x is 0.0 to 0.3 and Y is 0.1 to 0.5;
- and
- one or more copper alloy layers disposed over and contacting the zirconium-containing base layer;
- and
- a metal adhesion layer interposed between the substrate and the zirconium-containing base layer, the metal adhesion layer having a thickness from about 20 to 80 nm, wherein the one or more copper alloy layers are color matched to the zirconium-containing base layer.

A coated substrate comprising:
- a substrate;
- a zirconium-containing base layer disposed over the substrate, the zirconium-containing base layer being a zirconium carbonitride base layer or a zirconium nitride base layer;
- and
- one or more copper alloy layers disposed over the zirconium carbonitride base layer, each copper alloy layer including copper and nickel wherein nickel is present in an amount from about 10 to 25 weight percent of the total weight of each copper alloy layer with copper being present in an amount from about 75 to 90 weight percent of the total weight of each copper alloy layer;
- and
- a metal adhesion layer interposed between the substrate and the zirconium-containing base layer, the metal adhesion layer having a thickness from about 20 to 80 nm.
