3D Integration Technology for Lab-on-a-Chip Applications
Résumé
A review is presented of advances and challenges in fully integrated systems for personalised medicine applications. One key issue for the commercialisation of such systems is the disposability of the assay-substrate at a low cost. This work adds a new dimension to the integrated circuits technology for lab-on-a-chip systems by employing 3D integration for improved performance and functionality. It is proposed that a disposable biosensing layer can be aligned and temporarily attached to the 3D CMOS stack by the vertical interconnections, and can be replaced after each measurement.

Three-dimensional integrated circuit
A 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.
Circuit intégré
Le 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.
Circuit intégré à signaux mixtes
A 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.
