The redistribution layers excluding the lands and a first dielectric layer are covered with a second dielectric layer. After forming a first under bump metallurgy (UBM) layer on the land, a solder ball is reflowed to the first UBM layer. A second UBM layer is widely formed on the entire second dielectric layer that is the outer circumference of the first UBM layer and is connected to the redistribution layer through a via-hole. Therefore, the second UBM layer having a large area can be used as a ground plane or a power plane. In addition, the second UBM layer can electrically connect the redistribution layers physically separated from each other. Therefore, the plurality of redistribution layers can cross each other without being electrically shorted with each other.Type: GrantFiled: August 27, 2009Date of Patent: July 12, 2011Assignee: Amkor Technology, Inc.Inventors: No Sun Park, Young Suk Chung, Jae Beom Shim

Publication number: 20110163443Abstract: Methods for packaging microelectronic devices, microelectronic workpieces having packaged dies, and microelectronic devices re disclosed herein. One aspect of the invention is directed toward a microelectronic workpiece comprising a substrate having a device side and a backside. In one embodiment, the microelectronic workpiece further includes a plurality of dies formed on the device side of the substrate, a dielectric layer over the dies, and a plurality of bond-pads on the dielectric layer. The dies have integrated circuitry and a plurality of bond-pads electrically coupled to the integrated circuitry. The ball-pads are arranged in ball-pad arrays over corresponding dies on the substrate. The microelectronic workpiece of this embodiment further includes a protective layer over the backside of the substrate. The protective layer is formed on the backside of the substrate from a material that is in a flowable state and is then cured to a non-flowable state.Type: ApplicationFiled: July 12, 2010Publication date: July 7, 2011Applicant: ROUND ROCK RESEARCH, LLCInventor: James L.

FLIP-CHIP FAN-OUT WAFER LEVEL PACKAGE FOR PACKAGE-ON-PACKAGE APPLICATIONS, AND METHOD OF MANUFACTURE
Publication number: 20110156250Abstract: A flip-chip fan-out wafer level package for package-on-package applications includes a semiconductor die with solder bumps on an upper surface in a flip chip configuration. The die is inverted, with an upper surface facing an upper side of a redistribution layer, with the solder bumps in electrical contact with respective chip contact pads of the redistribution layer. The redistribution layer includes conductive traces that place each of the solder bumps in electrical contact with one or both of one of a plurality of upper redistribution contact pads and one of a plurality of lower redistribution contact pads. Each of the plurality of upper redistribution contact pads has an upper solder ball in electrical contact therewith. The die and the upper solder balls are at least partially encapsulated in a layer of mold compound positioned on the upper surface of the redistribution layer, and whose lateral dimensions are defined by the lateral dimensions of the redistribution layer.Type: ApplicationFiled: December 31, 2009Publication date: June 30, 2011Applicant: STMICROELECTRONICS ASIA PACIFIC PTE.
