Abstract

The present disclosure provides a method for forming a multilayer wiring structure, which includes: forming a patterned copper-phosphorous alloy layer over a carrier by performing a plating operation, and forming a dielectric layer over the patterned copper-phosphorous alloy layer. The forming the patterned copper-phosphorous alloy layer includes providing a plating solution having a copper source and a phosphorous source.
