Abstract:
A method of improving an interlayer adhesion property of low-k layers in a damascene process, the method comprising:providing a semiconductor substrate, a first conductive layer being formed within the semiconductor substrate; forming a first low-k layer upon the first conductive layer; performing a shallow ion implantation process for forming an etch stop layer within the first low-k layer; forming a second low-k layer on the surface of the etch stop layer; forming a passivation layer on the surface of the second low-k layer, wherein the first low-k layer, the etch stop layer, the second low-k layer, and the passivation layer together construct a laminated structure; and performing a damascene process to form a damascene opening in the laminated structure, the damascene opening penetrating the laminated structure and connecting with the first conductive layer.
