Encapsulation (électronique)In electronics manufacturing, integrated circuit packaging is the final stage of semiconductor device fabrication, in which the block of semiconductor material is encapsulated in a supporting case that prevents physical damage and corrosion. The case, known as a "package", supports the electrical contacts which connect the device to a circuit board. In the integrated circuit industry, the process is often referred to as packaging. Other names include semiconductor device assembly, assembly, encapsulation or sealing.
Circuit intégréLe circuit intégré (CI), aussi appelé puce électronique, est un composant électronique, basé sur un semi-conducteur, reproduisant une ou plusieurs fonctions électroniques plus ou moins complexes, intégrant souvent plusieurs types de composants électroniques de base dans un volume réduit (sur une petite plaque), rendant le circuit facile à mettre en œuvre. Il existe une très grande variété de ces composants divisés en deux grandes catégories : analogique et numérique.
Package on a packagePackage on a package (PoP) is an integrated circuit packaging method to vertically combine discrete logic and memory ball grid array (BGA) packages. Two or more packages are installed atop each other, i.e. stacked, with a standard interface to route signals between them. This allows higher component density in devices, such as mobile phones, personal digital assistants (PDA), and digital cameras, at the cost of slightly higher height requirements. Stacks with more than 2 packages are uncommon, due to heat dissipation considerations.
WaferEn électronique, un wafer (littéralement en français « tranche ») est une tranche ou une plaque très fine de matériau semi-conducteur monocristallin utilisée pour fabriquer des composants de microélectronique. En français, les termes de « tranche », « plaque » (voire, « plaquette ») ou « galette » sont également utilisés. Cependant, l'usage de l'anglais est très répandu dans les unités de fabrication de semi-conducteurs et dans le langage des ingénieurs.
Active packagingThe terms active packaging, intelligent packaging, and smart packaging refer to amplified packaging systems used with foods, pharmaceuticals, and several other types of products. They help extend shelf life, monitor freshness, display information on quality, improve safety, and improve convenience. The terms are often related and can overlap. Active packaging usually means having active functions beyond the inert passive containment and protection of the product.
Packaging and labelingPackaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use. Packaging contains, protects, preserves, transports, informs, and sells. In many countries it is fully integrated into government, business, institutional, industrial, and personal use.
SolderSolder (UKˈsɒldə,_ˈsəʊldə; NA: ˈsɒdər) is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling. Metals or alloys suitable for use as solder should have a lower melting point than the pieces to be joined. The solder should also be resistant to oxidative and corrosive effects that would degrade the joint over time. Solder used in making electrical connections also needs to have favorable electrical characteristics.
Brasagethumb|Brasage de composants électroniques. Le brasage des métaux, aussi appelé brasure, est un procédé d'assemblage permanent qui établit une liaison métallique entre les pièces réunies. Contrairement au soudage (soudure), il n'y a pas fusion des bords assemblés. Selon les cas, il peut y avoir ou non utilisation d'un . Le mécanisme du brasage consiste en la diffusion/migration atomique de part et d'autre de l'interface solide/solide dans le cas d'un brasage sans métal d'apport et de l'interface solide/liquide/solide lorsqu'un métal d'apport est utilisé.
Wafer-level packagingWafer-level packaging (WLP) is a process where packaging components are attached to an integrated circuit (IC) before the wafer – on which the IC is fabricated – is diced. In WSP, the top and bottom layers of the packaging and the solder bumps are attached to the integrated circuits while they are still in the wafer. This process differs from a conventional process, in which the wafer is sliced into individual circuits (dice) before the packaging components are attached.
System in packagethumb|Un SiP avec un processeur, mémoire et mémoire flash, combiné sur un seul substrat. Un SiP, acronyme de « System in Package » (système dans un boîtier, en français), aussi connu sous le nom de System-in-a-Package ou de Multi-Chip Module (MCM), désigne un système de circuits intégrés confinés dans un seul boîtier ou module. Le SiP permet de réaliser la totalité (ou presque) des fonctions habituelles d'un système électronique, tels que ceux présents à l'intérieur d'un téléphone mobile, d'un PC, d'un baladeur numérique, etc.
Multi-chip moduleA multi-chip module (MCM) is generically an electronic assembly (such as a package with a number of conductor terminals or "pins") where multiple integrated circuits (ICs or "chips"), semiconductor dies and/or other discrete components are integrated, usually onto a unifying substrate, so that in use it can be treated as if it were a larger IC. Other terms for MCM packaging include "heterogeneous integration" or "hybrid integrated circuit".
Three-dimensional integrated circuitA three-dimensional integrated circuit (3D IC) is a MOS (metal-oxide semiconductor) integrated circuit (IC) manufactured by stacking as many as 16 or more ICs and interconnecting them vertically using, for instance, through-silicon vias (TSVs) or Cu-Cu connections, so that they behave as a single device to achieve performance improvements at reduced power and smaller footprint than conventional two dimensional processes. The 3D IC is one of several 3D integration schemes that exploit the z-direction to achieve electrical performance benefits in microelectronics and nanoelectronics.
Packaging engineeringPackaging engineering, also package engineering, packaging technology and packaging science, is a broad topic ranging from design conceptualization to product placement. All steps along the manufacturing process, and more, must be taken into account in the design of the package for any given product. Package engineering is an interdisciplinary field integrating science, engineering, technology and management to protect and identify products for distribution, storage, sale, and use.
Câblage par filDans le domaine des semi-conducteurs, le câblage par fil ou pontage (traduction de wire bonding) est une des techniques utilisées pour effectuer les connexions électriques entre le boîtier et le die d'un circuit intégré. Le câblage est simplement réalisé par un fil (ou pont) soudé entre les deux plots de connexion prévus à cet usage sur chacun des éléments. La soudure est généralement réalisée par ultrasons. Le matériau du fil est de l'aluminium, de l'or ou du cuivre. Le diamètre du fil est de l'ordre de 20 μm.

En électronique, un die (de l'anglais) est un petit morceau rectangulaire résultant de la découpe d'un en sur lequel un circuit intégré a été fabriqué. Par extension, « en » désigne le circuit intégré lui-même sans son boîtier, et il est synonyme de puce électronique.
Linear integrated circuitA linear integrated circuit or analog chip is a set of miniature electronic analog circuits formed on a single piece of semiconductor material. The voltage and current at specified points in the circuits of analog chips vary continuously over time. In contrast, digital chips only assign meaning to voltages or currents at discrete levels. In addition to transistors, analog chips often include a larger number of passive elements (capacitors, resistors, and inductors) than digital chips.
Circuit intégré à signaux mixtesA mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die. Their usage has grown dramatically with the increased use of cell phones, telecommunications, portable electronics, and automobiles with electronics and digital sensors. Integrated circuits (ICs) are generally classified as digital (e.g. a microprocessor) or analog (e.g. an operational amplifier). Mixed-signal ICs contain both digital and analog circuitry on the same chip, and sometimes embedded software.
Hybrid integrated circuitA hybrid integrated circuit (HIC), hybrid microcircuit, hybrid circuit or simply hybrid is a miniaturized electronic circuit constructed of individual devices, such as semiconductor devices (e.g. transistors, diodes or monolithic ICs) and passive components (e.g. resistors, inductors, transformers, and capacitors), bonded to a substrate or printed circuit board (PCB). A PCB having components on a Printed Wiring Board (PWB) is not considered a true hybrid circuit according to the definition of MIL-PRF-38534.
Integrated circuit layout design protectionLayout designs (topographies) of integrated circuits are a field in the protection of intellectual property. In United States intellectual property law, a "mask work" is a two or three-dimensional layout or topography of an integrated circuit (IC or "chip"), i.e. the arrangement on a chip of semiconductor devices such as transistors and passive electronic components such as resistors and interconnections.
Plastic Leaded Chip CarrierUn boîtier de type PLCC (Plastic Leaded Chip Carrier) est un boîtier en plastique carré ou rectangulaire, portant des pattes de composants de type-“J” (à contacts plats) sur ses 4 côtés. Le nombre des pattes peut varier selon les types de 20 à 84. Elles sont espacées entre elles de 1,27 mm (0.05"). Les PLCCs sont conformes au standard JEDEC. L'un des avantages du boîtier PLCC est le gain de place du fait de l'utilisation de ses quatre côtés pour accéder au signaux du composant.
