Abstract

A method of fabricating a semiconductor package includes providing a substrate having at least one contact and forming a redistribution layer on the substrate. The formation of the redistribution layer includes forming a dielectric material layer over the substrate and performing a double exposure process to the dielectric material layer. A development process is then performed and a dual damascene opening is formed in the dielectric material layer. A seed metallic layer is formed over the dual damascene opening and over the dielectric material layer. A metal layer is formed over the seed metallic layer. A redistribution pattern is formed in the first dual damascene opening and is electrically connected with the at least one contact.
