StepperA stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. Stepper is short for step-and-repeat camera. Steppers are an essential part of the complex process, called photolithography, which creates millions of microscopic circuit elements on the surface of silicon wafers out of which chips are made. These chips form the heart of ICs such as computer processors, memory chips, and many other devices.
NanotechnologieLes nanosciences et nanotechnologies (d’après le grec , « nain »), ou NST, peuvent être définies au minimum comme l’ensemble des études et des procédés de fabrication et de manipulation de structures (physiques, chimiques ou biologiques), de dispositifs et de systèmes matériels à l’échelle du nanomètre (nm), qui est l'unité la plus proche de la distance entre deux atomes. Les NST présentent plusieurs acceptions liées à la nature transversale de cette jeune discipline.
Embarrassingly parallelIn parallel computing, an embarrassingly parallel workload or problem (also called embarrassingly parallelizable, perfectly parallel, delightfully parallel or pleasingly parallel) is one where little or no effort is needed to separate the problem into a number of parallel tasks. This is often the case where there is little or no dependency or need for communication between those parallel tasks, or for results between them. Thus, these are different from distributed computing problems that need communication between tasks, especially communication of intermediate results.
