ISO/TS 80004-8:2013(E)
Introduction
Nanomanufacturing is the essential bridge between the discoveries of the nanosciences and real-world
nanotechnology products.
Advancing nanotechnology from the laboratory into volume production ultimately requires careful
study of manufacturing process issues including product design, reliability and quality, process design
and control, shop floor operations, supply chain management, workplace safety and health practices
during the production, use, and handling of nanomaterials. Nanomanufacturing encompasses directed
self assembly and assembly techniques, synthetic methodologies, and fabrication processes such as
lithography and biological processes. Nanomanufacturing also includes bottom-up directed assembly,
top-down high resolution processing, molecular systems engineering, and hierarchical integration with
larger scale systems. As dimensional scales of materials and molecular systems approach the nanoscale,
the conventional rules governing their behaviour may change significantly. As such, the behaviour of a
final product is enabled by the collective performance of its nanoscale building blocks.
Biological process terms are not included in this first edition of the nanomanufacturing vocabulary, but
considering the rapid development of the field, it is expected that terms in this important area will be
added in a future update to this Technical Specification or in companion documents in the 80004 series.
This could include both the processing of biological nanomaterials and the use of biological processes to
manufacture materials at the nanoscale.
Similarly, additional terms from other developing areas of nanomanufacturing, including composite
manufacturing, roll-to-roll manufacturing, and others, will be included in future documents.
There is a distinction between the terms nanomanufacturing and nanofabrication. Nanomanufacturing
encompasses a broader range of processes than does nanofabrication. Nanomanufacturing
encompasses all nanofabrication techniques and also techniques associated with materials processing
and chemical synthesis.
This document provides an introduction to processes used in the early stages of the nanomanufacturing
value chain, namely the intentional synthesis, generation or control of nanomaterials, including
fabrication steps in the nanoscale. The nanomaterials that result from these manufacturing processes
are distributed in commerce where, for example, they may be further purified, be compatabilized to
be dispersed in mixtures or composite matrices, or serve as integrated components of systems and
devices. The nanomanufacturing value chain is, in actuality, a large and diverse group of commercial
value chains that stretch across these sectors:
— the semiconductor industry (where the push to create smaller, faster, and more efficient
microprocessors heralded the creation of circuitry less than 100 nm in size);
— electronics and telecommunications;
— aerospace, defence, and national security;
— energy and automotive;
— plastics and ceramics;
— forest and paper products;
— food and food packaging;
— pharmaceuticals, biomedicine, and biotechnology;
— environmental remediation;
— clothing and personal care.
There are thousands of tonnes of nanomaterials on the market with end use applications in several of
these sectors, such as carbon black and fumed silica. Nanomaterials which are rationally designed with
vi © ISO 2013 – All rights reserved

specific purpose are expected to radically change the landscape in areas such as biotechnology, water
purification, and energy development.
The majority of sections in this document are organized by process type. In the case of section 6, the logic
of placement is as follows: in the step before the particle is made, the material itself is in a gas/liquid/
solid phase. The phase of the substrate or carrier in the process does not drive the categorization of
the process. As an example, consider iron particles that are catalysts in a process by which you seed oil
with iron particles, the oil vaporizes and condenses forming carbon particles on the iron particles. What
vaporizes is the oil, and therefore it is a gas phase process. Nanotubes grown from the gas phase, starting
with catalyst particles that react with the gas phase to grow the nanotubes, thus this is characterized
as a gas process. Indication of whether synthesis processes are used to manufacture nano-objects,
nanoparticles, or both, is provided in Annex A.
A common understanding of the terminology used in practical applications will enable communities of
practice in nanomanufacturing and will advance nanomanufacturing strength worldwide. Extending
the understanding of terms across the existing manufacturing infrastructure will serve to bridge
the transition between the innovations of the research laboratory and the economic viability of
nanotechnologies.

Introduction
La nanofabrication constitue le pont essentiel entre les découvertes du domaine des nanosciences et les

produits du monde réel issus des nanotechnologies.

Le passage des nanotechnologies du laboratoire à la production de masse exige, à terme, une étude

approfondie des questions liées aux procédés de fabrication, y compris la conception, la fiabilité et

la qualité des produits, la conception et la maîtrise des procédés, les opérations en atelier, la gestion

de la chaîne d’approvisionnement, les pratiques de sécurité et de santé sur le lieu de travail durant

la production, l’utilisation et la manipulation de nanomatériaux. La nanofabrication englobe des

techniques d’assemblage et d’auto-assemblage dirigé, des méthodologies de synthèse et des procédés de

fabrication tels que la lithographie et des processus biologiques. La nanofabrication comprend également
l’assemblage dirigé par approche ascendante («bottom-up»), le traitement à haute résolution par approche
descendante («top-down»), l’ingénierie des systèmes moléculaires et l’intégration hiérarchique avec des
systèmes à plus grande échelle. Au fur et à mesure que les échelles dimensionnelles des matériaux et des
systèmes moléculaires se rapprochent de l’échelle nanométrique, les règles conventionnelles régissant
leur comportement peuvent varier considérablement. À ce titre, le comportement d’un produit final est
directement lié à la performance collective de ses constituants de base à l’échelle nanométrique.
Les termes propres aux procédés biologiques ne sont pas inclus dans cette première édition du
vocabulaire de la nanofabrication mais, compte tenu de l’évolution rapide dans ce domaine, il est prévu
que les termes propres à cet important domaine soient ajoutés lors d’une mise à jour ultérieure de la
présente Spécification technique ou dans des documents accompagnant la série de normes 80004. Ces
documents pourraient inclure à la fois le traitement des nanomatériaux biologiques et l’utilisation de
procédés biologiques pour la fabrication de matériaux à l’échelle nanométrique.
De la même manière, des termes supplémentaires issus d’autres domaines de nanofabrication en
développement, y compris la fabrication de composites, la fabrication «roll-to-roll» et autres techniques,
seront inclus dans de futurs documents.
Une distinction doit être faite entre les termes «nanofabrication» et «nanoconstruction». Le
«nanofabrication» englobe un éventail de procédés plus vaste que celui de la «nanoconstruction». Le
«nanofabrication» englobe toutes les techniques de «nanofabrication», ainsi que les techniques associées
au traitement des matériaux et à la synthèse chimique.
Le présent document se veut une introduction aux processus utilisés pour les premières étapes de la
chaîne de valeur de la nanofabrication, c’est-à-dire la synthèse, la production ou le contrôle intentionnels
de nanomatériaux, y compris les étapes de fabrication à l’échelle nanométrique. Les nanomatériaux issus
de ces processus de fabrication sont commercialisés lorsqu’ils peuvent, par exemple, faire l’objet d’une
purification supplémentaire, être rendus compatibles pour une dispersion dans des mélanges ou des
matrices composites, ou servir de composants intégrés dans des systèmes et des appareils. En réalité,
la chaîne de valeur de la nanofabrication est un ensemble important et diversifié de chaînes de valeur

commerciales qui couvrent les secteurs suivants:
— l’industrie des semi-conducteurs (où la pression exercée pour créer des microprocesseurs plus
petits, plus rapides et plus performants a conduit à la création de circuits inférieurs à 100 nm);
— l’électronique et les télécommunications;
— l’aérospatiale, la défense et la sécurité nationale;
— l’énergie et l’industrie automobile;
— l’industrie plastique et l’industrie céramique;
— les produits forestiers et papiers;
— l’alimentation et l’emballage alimentaire;
— l’industrie pharmaceutique, la biomédecine et les biotechnologies;

Sur le marché, des milliers de tonnes de nanomatériaux font l’objet d’applications finales dans plusieurs

des secteurs en question, tels que le noir de carbone et la fumée de silice. Les nanomatériaux qui sont

conçus de manière rationnelle dans un but spécifique sont censés bouleverser le paysage de secteurs

tels que les biotechnologies, l’assainissement de l’eau et le développement énergétique.

La plupart des parties du présent document sont organisées par type de processus. Dans le cas de

l’Article 6, la logique de classement est la suivante: avant la fabrication de la particule, le matériau

lui-même est en phase gazeuse/liquide/solide. La phase du substrat ou porteur dans le processus ne

détermine pas la catégorisation du processus. Par exemple, des particules de fer sont des catalyseurs
pour un processus dans lequel de l’huile est ensemencée par des particules de fer, l’huile se vaporise
puis se condense, formant des particules de carbone sur les particules de fer. Dans la mesure où l’huile
est l’élément qui se vaporise, il s’agit d’un processus en phase gazeuse. Du fait que les nanotubes sont
synthétisés en phase gazeuse, en présence de particules de catalyseur réagissant avec la phase gazeuse
pour produire les nanotubes, ce processus est caractérisé comme étant
