De temps en temps, la technologie du transistor devient important car elle décide quelle ère est on.

En principe, un transistor représente un interrupteur dans le circuit qui permet de faire passer le courant ou pas selon l’entrée de la base, le contact au milieu.

Par exemple:

Pour PMOS, si l’on alimente la base (on appelle aussi la grille G), le transistor devient un interrupteur ouvert. Si elle n’est pas alimentée, le courant traverse le transistor.

Pour CMOS, c’est l’inverse, voir le figure.

Selon la technologie du transistor, on a des catégories différentes:

Program Tracks
equipment, design, fabrication, characterization Fabrication, Characterization & Tools
(MEMS & Nano Design, Simulation & Modeling, Fabrication, Diagnostics, Characterization, Instrumentation)
chemical & materials Advanced Materials
(Particles, CNT, Coatings, Polymers, Composites, Soft & Bio Materials)
electronics & systems Electronics & Microsystems
(MEMS, NEMS, Sensors, Nano Electronics, Photonics, Fluidics, Modeling, WCM)
medical & biotech Medical & Biotech
