Patent attributes
A method includes mounting a wafer-level package substrate over a carrier, and pre-cutting the wafer-level package substrate to form trenches extending from a top surface of the wafer-level package substrate into the wafer-level package substrate. A plurality of dies is bonded over the wafer-level package substrate. The plurality of dies is molded in a molding material to form a wafer-level package, with the wafer-level package including the wafer-level package substrate, the plurality of dies, and the molding material. The carrier is detached from the wafer-level package. The wafer-level package is sawed into a plurality of packages, with each of the plurality of packages including a portion of the wafer-level package substrate and one of the plurality of dies.
