Patent number: 8877558Abstract: A method of making an electronic device includes forming an electrically conductive pattern on a substrate, forming a coverlay layer on the substrate and the electrically conductive pattern, forming a partially cured, tacky adhesive layer on the coverlay layer, and forming openings in the coverlay layer and the partially cured, tacky adhesive layer aligned with the electrically conductive pattern. The method includes positioning an IC on the partially cured, tacky adhesive layer and thereafter curing the partially cured tacky adhesive layer to thereby simultaneously mechanically secure and electrically interconnect the IC to the substrate, the IC having bond pads on a surface thereof.Type: GrantFiled: February 7, 2013Date of Patent: November 4, 2014Assignee: Harris CorporationInventors: Andrew Craig King, Michael Raymond Weatherspoon, Louis J. Rendek, Jr.

Patent number: 8847410Abstract: A semiconductor device includes a semiconductor chip, a die pad including an obverse surface on which the semiconductor chip is bonded, a lead spaced apart from the die pad, a bonding wire electrically connecting the semiconductor chip and the lead to each other, and a resin package that seals the semiconductor chip and the bonding wire. The bonding wire includes a first bond portion press-bonded to the semiconductor chip by ball bonding, a second bond portion press bonded to the lead by stitch bonding, a landing portion extending from the second bond portion toward the die pad and formed in contact with an obverse surface of the lead, and a loop extending obliquely upward from the landing portion toward the semiconductor chip.Type: GrantFiled: August 21, 2012Date of Patent: September 30, 2014Assignee: Rohm Co., Ltd.Inventors: Kosuke Miyoshi, Kinya Sakoda, Toshikuni Shinohara

Patent number: 8835225Abstract: A Quad Flat No-Lead (QFN) semiconductor package includes a die pad; I/O connections disposed at the periphery of the die pad; a chip mounted on the die pad; bonding wires; an encapsulant for encapsulating the die pad, the I/O connections, the chip and the bonding wires while exposing the bottom surfaces of the die pad and the I/O connections; a surface layer formed on the bottoms surfaces of the die pad and the I/O connections; a dielectric layer formed on the bottom surfaces of the encapsulant and the surface layer and having openings for exposing the surface layer. The surface layer has good bonding with the dielectric layer that helps to prevent solder material in a reflow process from permeating into the die pad and prevent solder extrusion on the interface of the I/O connections and the dielectric layer, thereby increasing product yield.Type: GrantFiled: December 4, 2013Date of Patent: September 16, 2014Assignee: Siliconware Precision Industries Co., Ltd.Inventors: Fu-Di Tang, Ching-Chiuan Wei, Yung-Chih Lin

Patent number: 8829691Abstract: A light-emitting device package includes: a package body on which a mount portion and a terminal portion are disposed; a light-emitting device chip that is mounted on the mount portion; and a bonding wire that electrically connects an electrode of the light-emitting device chip and the terminal portion. The bonding wire includes a rising portion that rises from the light-emitting device chip to a loop peak, and an extended portion that connects the loop peak and the terminal portion. A first kink portion, which is bent in a direction intersecting a direction in which the rising portion rises, is disposed on the rising portion.Type: GrantFiled: September 25, 2011Date of Patent: September 9, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-yun Lim, Kook-jin Oh, Joon-gil Lee

Patent number: 8829678Abstract: One embodiment provides a semiconductor package by forming a redistribution layer extending from a bonding pad of a semiconductor chip using a photoresist pattern plated with the seed layer. Fabrication of the semiconductor package is relatively simple thereby shortening a manufacturing time and reducing the manufacturing cost, and which can increase an adhered area of input/output terminals and can prevent delamination by connecting and welding the input/output terminals to a pair of redistribution layers.Type: GrantFiled: January 11, 2013Date of Patent: September 9, 2014Inventors: Jeong Seok Lee, In Tae Kim, Jae Sik Park, Dai Hyun Jung

Patent number: 8815730Abstract: A method for forming bond pads on a semiconductor die includes forming a dielectric stack including a bottom and top dielectric layer having a contact hole therethrough over a bond pad. An outer edge of the bottom dielectric layer within the contact hole extends beyond an outer edge of the top dielectric layer to define a bond pad edge. A second metal layer on a first metal layer is deposited. A first photoresist layer is formed exclusively within the contact hole. The second metal layer is wet etched to recess the second metal layer from sidewalls of the bottom dielectric layer in the contact hole. A second photoresist layer is formed exclusively within the contact hole. The first metal layer is wet etched to recess the first metal layer from the top dielectric layer. The first metal layer extends over the bond pad edge onto the bottom dielectric layer.Type: GrantFiled: July 3, 2013Date of Patent: August 26, 2014Assignee: Texas Instruments IncorporatedInventors: Jing Wang, Lin Lin, Qiuling Jia, Qi Yang, Jianxin Liu

Patent number: 8815732Abstract: After forming a pressure-bonded ball and a ball neck by bonding an initial ball to a pad, a capillary is moved upward, away from a lead, and then downward, thereby the ball neck is trodden on by a face portion that is on the lead side of the capillary. Subsequently, the capillary is moved upward and then toward the lead until the face portion of the capillary is positioned above the ball neck, thereby a wire is folded back toward the lead. Then, the capillary is moved downward such that a side of the wire is pressed by the capillary against the ball neck that has been trodden on. After the capillary is moved obliquely upward toward the lead and then looped toward the lead, the wire is pressure-bonded to the lead.Type: GrantFiled: February 15, 2012Date of Patent: August 26, 2014Assignee: Shinkawa Ltd.Inventors: Tatsunari Mii, Shinsuke Tei, Hayato Kiuchi
