Abstract:
A shield for shielding a portion of an electronic component from undesirable emissions from neighboring components. The shield comprises a metal body configured to be attached to a substrate, and solder selectively applied to a lower portion of the metal body in manner that allows for both location and volume of the solder to be controlled. A bond is created between the solder and the metal body. The bond may be a metallurgical bond created by proximity of the solder to the at least one leg and sufficient heat and time to bring the solder to a melting temperature of the solder; or a diffusion bond created by heat and pressure. A method of attaching the shield to the substrate is also described.
Abstract:
Disclosed herein are integrated circuit (IC) packages with temperature sensor traces, and related systems, devices, and methods. In some embodiments, an IC package may include a package substrate and an IC die disposed on the package substrate, wherein the package substrate includes a temperature sensor trace, and an electrical resistance of the temperature sensor trace is representative of an equivalent temperature of the temperature sensor trace.

Abstract:
Die Erfindung betrifft ein Verfahren zum Montieren eines elektrischen Bauelements (12) auf einen Substrat (13). Erfindungsgemäß wird das Fügen durch eine Haube (11) vereinfacht, indem in diese Haube eine Kontaktierungsstruktur (16) vorgesehen ist und diese beim Aufsetzen der Haube (11) auf verschiedenen Fügeleveln (28, 29) gleichzeitig mit einem Zusatzwerkstoff (35) gefügt wird. Weiterhin bezieht sich die Erfindung auf eine Haube, welche zur Anwendung in dem genannten Verfahren geeignet ist. Erfindungsgemäß besteht die Haube aus einem thermisch erweichbaren oder thermisch aushärtbaren Material, vorzugsweise aus einem Harz oder einem thermoplastischen Kunststoff. Die Haube wird vorzugsweise beim Fügen der Verbindungen soweit erwärmt, dass diese sich plastisch verformen lässt. Vorteilhaft werden auf diese Weise Toleranzen beim Fügen ausgeglichen, so dass es zu einer zuverlässigen Ausbildung aller Verbindungen kommen kann. Außerdem kann über die Haube ein erforderlicher Fügedruck aufgebaut werden, wie er beispielsweise bei Diffusionsverbindungen oder Sinterverbindungen der elektrischen Kontakte erforderlich ist.
Abstract:
Methods for temporary wafer molding for chip-on-wafer assembly may include bonding one or more semiconductor die to an interposer wafer, applying a temporary mold material to encapsulate the bonded die, and backside processing the interposer, which may be singulated to generate assemblies comprising the bonded die, the interposer die, which may be bonded to packaging substrates. The temporary mold material may be removed and the bonded die may be tested. Additional die may be bonded to the assemblies based on the electrical testing. The interposer may be singulated utilizing one or more of: a laser cutting process, reactive ion etching, a sawing technique, and a plasma etching process. The backside processing may comprise thinning the interposer wafer to expose through-silicon-vias (TSVs) and placing metal contacts on the exposed TSVs. The die may be bonded to the interposer utilizing a mass reflow or thermal compression process.

Abstract:
A shielding apparatus useful in the attenuation of electronic noise or spurious electric signals is disclosed. In one embodiment, the shielding apparatus is encapsulated with an electronic component such as an integrated circuit. At least parts of the apparatus are formed using a selective metal deposition process (e.g., electroforming) that increases manufacturing efficiency and provides enhanced mechanical and structural features, as well as reduced cost. In another embodiment, the shielding apparatus comprises an array. Methods of manufacturing and utilizing the shielding apparatus are also disclosed.
Abstract:
The invention relates in one aspect to a method of micro-packaging a component. At least a first and a second semi-conductor substrate are provided, one of which has electrical through connections (vias). A depression in either one of said substrates or in both is etched. A component is provided above vias and connected thereto. The substrates are joined to form a sealed package. The invention also relates to a micro-packaged electronic or micromechanic device, comprising a thin-walled casing of a semi-conductor material having electrical through connections through the bottom of the casing. An electronic or micromechanic component is attached to said electrical through connections, and the package is hermetically sealed for maintaining a desired atmosphere, suitably vacuum inside the box.
