Abstract: A method includes providing a die having a contact pad on a top surface and forming a conductive protective layer over the die and covering the contact pad. A molding compound is formed over the die and the conductive protective layer. The conductive protective layer is exposed using a laser drilling process. A redistribution layer (RDL) is formed over the die. The RDL is electrically connected to the contact pad through the conductive protective layer.

Abstract: A package structure and method for forming the same are provided. The package structure includes a substrate and a semiconductor die formed over the substrate. The package structure also includes a package layer covering the semiconductor die and a conductive structure formed in the package layer. The package structure includes a first insulating layer formed on the conductive structure, and the first insulating layer includes monovalent metal oxide. A second insulating layer is formed between the first insulating layer and the package layer. The second insulating layer includes monovalent metal oxide, and a weight ratio of the monovalent metal oxide in the second insulating layer is greater than a weight ratio of the monovalent metal oxide in first insulating layer.
