20090045507 | Flip chip interconnection - Methods for forming flip chip interconnection, in which the bump interconnect is defined at least in part by an underfill. The underfill includes a material that is thermally cured; that is, raising the temperature of the underfill material can result in progressive curing of the underfill through stages including a gel stage and a fully cured stage. According to the invention, during at least an early stage in the process the semiconductor chip is carried by a thermode, which is employed to control the temperature of the assembly in a specified way. Also, flip chip interconnections and flip chip packages made according to the methods of invention. | 02-19-2009 |
20090283890 | SEMICONDUCTOR MULTI-PACKAGE MODULE INCLUDING TAPE SUBSTRATE LAND GRID ARRAY PACKAGE STACKED OVER BALL GRID ARRAY PACKAGE - A single metal layer tape substrate includes a patterned metal layer affixed to a patterned dielectric layer. The dielectric layer is patterned to provide openings exposing lands and bond sites on bond fingers on the land side of the metal layer. The metal layer is patterned to provide circuit traces as appropriate for interconnection with the die (on the die attach side) and with other elements (such as other packages in a multi-package module). Interconnection with a die is made by wire bonding to exposed traces on a die attach side of the metal layer, and bond fingers and lands for access to testing the package are provided on the opposite (land) side of the metal layer. | 11-19-2009 |
20100136744 | METHOD FOR MAKING SEMICONDUCTOR MULTIPACKAGE MODULE INCLUDING DIE AND INVERTED LAND GRID ARRAY PACKAGE STACKED OVER BALL GRID ARRAY PACKAGE - A method for making a multipackage module that has multiple die of various types and having various functions and, in some embodiments, the module includes a digital processor, an analog device, and memory. A first die, having a comparatively large footprint, is mounted onto first die attach region on a surface of a first package substrate. A second die, having a significantly smaller footprint, is mounted upon the surface of the first die, on a second die attach region toward one edge of the first die. The first die is electrically connected by wire bonds to conductive traces in the die-attach side of the substrate. The second die is electrically connected by wire bonds to the first package substrate, and may additionally be electrically connected by wire bonds to the first die. | 06-03-2010 |
20100200966 | SEMICONDUCTOR MULTI-PACKAGE MODULE HAVING PACKAGE STACKED OVER DIE-UP FLIP CHIP BALL GRID ARRAY PACKAGE AND HAVING WIRE BOND INTERCONNECT BETWEEN STACKED PACKAGES - A semiconductor multi-package module having stacked second and first packages, each package including a die attached to a substrate, in which the first and second package substrates are interconnected by wire bonding, and in which the first package is a flip chip ball grid array package in a die-up configuration. Also, a method for making a semiconductor multi-package module, by providing a first package including a first package substrate and having a die-up flip chip configuration, affixing a second package including a second package substrate an upper surface of the first package, and forming z-interconnects between the first and second package substrates. | 08-12-2010 |
20100200967 | INTEGRATED CIRCUIT PACKAGE SYSTEM INCLUDING SHIELD - An integrated circuit package system includes: a substrate; a first device attached to the substrate; a shield attached to the substrate and surrounding the first device; apertures formed within the shield; the shield configured to block electromagnetic energy that passes through the apertures; and an encapsulation material deposited through the apertures. | 08-12-2010 |
20110115099 | Flip-chip underfill - A method for flip-chip interconnection includes applying a dielectric film onto the active side of the die, or onto the die mount side of the substrate, or both onto the die and onto the substrate; then orienting and aligning the die in relation to the substrate, and moving the die toward the substrate so that interconnect contact is made; then treating the assembly (for example by heating or by heating and pressing) to complete the electrical connections and to cause the film to soften and to adhere. Also, a method for flip-chip assembly includes completing electrical connection of the flip-chip interconnects on a die with bond pads on a substrate and thereafter exposing the assembly to a CVD process to fill the headspace between the die and the substrate with a dielectric material. Also, a flip-chip assembly is made by the method. Also, a die or a substrate is prepared for flip-chip interconnection by applying a dielectric film on a surface thereof. | 05-19-2011 |
