Abstract
A method of forming an integrated circuit structure is provided. In an embodiment, the method includes bonding top dies onto a bottom wafer and then molding a first molding material onto and in between the top dies and the bottom wafer. The bottom wafer, the top dies, and the first molding material are sawed to form molding units. Each of the molding units includes one of the top dies and a bottom die sawed from the bottom wafer. The molding units are bonded onto a package substrate and a second molding material is molding onto the one of the molding units and the package substrate. Thereafter, the package substrate and the second molding material are sawed to form package-molded units.
