Patent number: 9837336Abstract: A semiconductor device has a plurality of conductive vias formed into a semiconductor wafer. A portion of the semiconductor wafer is removed so the conductive vias extend above a surface of the semiconductor wafer. A notch is formed in the semiconductor wafer around each of the conductive vias. The notch around the conductive vias can be formed by wet etching, dry etching, or LDA. A first insulating layer is formed over a surface of the semiconductor wafer and conductive vias and into the notch to provide stress relief between the conductive vias and semiconductor wafer. A portion of the first insulating layer is removed to expose the conductive vias. A first conductive layer and second insulating layer can be formed around the conductive vias. A second conductive layer can be formed over the conductive vias. The notch can extend into the second insulating layer.Type: GrantFiled: April 21, 2014Date of Patent: December 5, 2017Assignee: STATS ChipPAC, Pte. Ltd.Inventors: Won Kyoung Choi, Chang Bum Yong, Jae Hun Ku

Patent number: 9362210Abstract: Metal leadframes, semiconductor packages made using the leadframes, and methods of making the leadframes and packages are disclosed. In one embodiment, the leadframe includes a rectangular frame. A chip pad and a plurality of leads are within the frame. The lower side of the chip pad and the leads includes one or more vertically recessed horizontal surfaces. The upper side of the chip pad may include a groove around a chip mounting region. In a package, the chip pad supports a semiconductor chip electrically connected to the leads. The lower side of the chip pad and leads are exposed at an exterior surface of the package body. Encapsulant material underfills the recessed lower surfaces of the chip pad and leads, thereby locking them to the encapsulant material. A wire may be reliably bonded to the chip pad within the groove formed in the upper side thereof.Type: GrantFiled: February 10, 2013Date of Patent: June 7, 2016Assignee: Amkor Technology, Inc.Inventors: Byung Hoon Ahn, Jae Hun Ku, Young Suk Chung, Suk Gu Ko, Sung Sik Jang, Young Nam Choi, Won Chul Do
