20120013005 | Packaging Structure and Method - A method of making a semiconductor device includes providing a substrate and forming a conductive layer on the substrate. The conductive layer includes a first metal. A semiconductor die is provided. A bump is formed on the semiconductor die. The bump includes a second metal. The semiconductor die is positioned proximate to the substrate to contact the bump to the conductive layer and form a bonding interface. The bump and the conductive layer are metallurgically reacted at a melting point of the first metal to dissolve a portion of the second metal from an end of the bump. The bonding interface is heated to the melting point of the first metal for a time sufficient to melt a portion of the first metal from the conductive layer. A width of the conductive layer is no greater than a width of the bump. | 01-19-2012 |

20130050571 | CAMERA MODULE HOUSING HAVING BUILT-IN CONDUCTIVE TRACES TO ACCOMMODATE STACKED DIES USING FLIP CHIP CONNECTIONS - A camera module including a housing with embedded conductive traces that allow for an increase in usable surface area of a corresponding printed circuit board (PCB) or multi-layer substrate, a reduced overall thickness of the module, a reduction in tilt management of a lens element of the module, and a facilitation in alignment of the lens element relative to the image sensor. An image sensor is electrically interconnected to first portions of the conductive traces by way of a flip chip process, and then the housing may be mounted over the PCB so that second portions of the conductive traces interconnect with corresponding conductive pads on the PCB to electrically interconnect the image sensor die to the PCB. In one arrangement, another die may be electrically interconnected to the PCB so that as assembled, the die is disposed between the image sensor and the PCB. | 02-28-2013 |
20130083239 | FOLDED TAPE PACKAGE FOR ELECTRONIC DEVICES - Described herein is a folded tape package for electronic devices. The folded tape package uses a flexible tape substrate having two end sections for passive components and a middle section for connecting and stacking multiple dies. The stacked dies are encapsulated or covered with a mold. One side may be left exposed for device functionality and operation with additional components or devices. The passive components may also be covered with a mold. The end sections are folded such that the end sections are in a parallel configuration with the middle section. The flexible tape substrate may be a high density interconnect flexible tape substrate with two layers. A silicon substrate may be used to interconnect a die stack to the flexible tape substrate. The folded tape package has a reduced device footprint, lower substrate warpage effects, and higher substrate yields. | 04-04-2013 |

20130113093 | Semiconductor Device and Method of Forming a Metallurgical Interconnection Between a Chip and a Substrate in a Flip Chip Package - A method for forming metallurgical interconnections and polymer adhesion of a flip chip to a substrate includes providing a chip having a set of bumps formed on a bump side thereof and a substrate having a set of interconnect points on a metallization thereon, providing a measured quantity of a polymer adhesive in a middle region of the chip on the bump side, aligning the chip with the substrate so that the set of bumps aligns with the set of interconnect points, pressing the chip and the substrate toward one another so that a portion of the polymer adhesive contacts the substrate and the bumps contact the interconnect points, and heating the bumps to a temperature sufficiently high to form a metallurgical connection between the bumps and the interconnect points. | 05-09-2013 |
20130128106 | CAMERA MODULE HOUSING HAVING MOLDED TAPE SUBSTRATE WITH FOLDED LEADS - A camera module including a flexible tape substrate (e.g., a flexible printed circuit tape portion) having a plurality of surface mount components and a first frame member mounted to a first side of the substrate and an image sensor and a frame member mounted to an opposing second side of the substrate. The substrate includes a body portion and one or more leads or wing members having conductive contacts thereon extending from the body portion. The wing members may be folded onto the second frame member so that the conductive contacts of the wing members generally face in a different direction than conductive contacts of the body portion to provide an electrical path to the surface mount components in a manner that is free of using vias extending through the substrate. A tubular housing and lens barrel may be mounted to the substrate over the first frame member. | 05-23-2013 |
20140110162 | STACKED PACKAGES USING LASER DIRECT STRUCTURING - Described herein is a stacked package using laser direct structuring. The stacked package includes a die attached to a substrate. The die is encapsulated with a laser direct structuring mold material. The laser direct structuring mold material is laser activated to form circuit traces on the top and side surfaces of the laser direct structuring mold material. The circuit traces then undergo metallization. A package is then attached to the metalized circuit traces and is electrically connected to the substrate via the metalized circuit traces. | 04-24-2014 |

20140239342 | LED BACK END ASSEMBLY AND METHOD OF MANUFACTURING - An LED device and method of manufacture including separately coupling a thin flexible interposer and an LED die to a heat sink structure and then electrically coupling the interposer and the LED die together with a wirebond. A specifically shaped perimeter of an aperture within the interposer negates the need for a cavity or alignment markings within the heat sink structure by limiting the orientation in which the die fits within the aperture. Alternatively, an LED device and method of manufacture include coupling a rigid circuit board to an LED die such that electrical contacts of the die are electrically coupled with electrical input/output terminals of the circuit board. This die/board unit is then able to be coupled to a heat sink structure to form a portion of the device. | 08-28-2014 |
