Patent ID: 7273768

Claim:
A wafer-level package and an IC module assembly method for the wafer-level package comprising: forming a metal bump on a wafer: printing a conductive metal paste on an I/O pad of the wafer with a steel plate printing technique, then solidifying to form the metal bump; applying a high polymer resin coating: applying the high polymer resin coating to the surface of the wafer over the metal bump with a printing technique and solidifying the resin coating; grinding a surface of the resin coating: grinding the solidified resin coating on the surface of the wafer until the metal bump is exposed and a required thickness of the resin coating is reached; printing an endpoint on the exposed metal bump: an endpoint referring to a joint point of a wafer die part and an antenna or a substrate; grinding and cutting: grinding a back side of the wafer to a required thickness, then cutting the wafer into multiple chips to complete a package process; and bonding the chips to an antenna or substrate with SMT (surface mounting technology).
