All the process terms in this document are relevant to nanomanufacturing, however, many of the listed
processes are not exclusively relevant to the nanoscale. Terms that are not exclusive are noted within
the definitions. Depending on controllable conditions, such processes can result in material features at
the nanoscale or, alternatively, at larger scales.
There are many other terms that name tools, components, materials, systems control methods or
metrology methods associated with nanomanufacturing that are beyond the scope of this document.
Terms and definitions from other parts of the ISO/TS 80004 series are reproduced in Clause 3 for
context and better understanding.

Nanotechnologien - Fachwörterverzeichnis - Teil 8: Industrieller Nanoherstellungsprozess (ISO/TS 80004-8:2020)

Dieses Dokument legt Begriffe zu industriellen Nanoherstellungsprozessen auf dem Gebiet der Nanotechnologien fest.
Alle in diesem Dokument enthaltenen prozessbezogenen Begriffe sind für die industrielle Nanoherstellung von Bedeutung, viele der aufgeführten Prozesse jedoch sind nicht ausschließlich auf den Nanomaßstab anwendbar. Begriffe, die nicht in dieser Weise exklusiv sind, sind in den Definitionen als solche gekennzeichnet. In Abhängigkeit von regelbaren Bedingungen können derartige Prozesse zu Materialeigenschaften im Nanomaßstab oder alternativ auch in größeren Maßstäben führen.
Es gibt im Zusammenhang mit der industriellen Nanoherstellung viele weitere Begriffe, die Werkzeuge, Teile, Werkstoffe, Verfahren zur Systemkontrolle oder Messtechnik-Verfahren bezeichnen, die aber nicht Gegenstand des Anwendungsbereiches dieses Dokumentes sind.
Um den Zusammenhang zu verdeutlichen und für ein besseres Verständnis zu sorgen, werden in Abschnitt 3 Begriffe aus anderen Teilen der Reihe ISO/TS 80004 wiedergegeben.

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 second 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 document or in companion documents in the ISO/TS 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 that are rationally designed with

specific purpose are expected to radically change the landscape in areas such as biotechnology, water
purification and energy development.
The majority of clauses in this document are organized by process type. In Clause 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 grow 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.
In addition, Annex A identifies the processes that are also applicable to macroscopic materials and are
therefore not exclusively relevant to nanomanufacturing. 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
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 second 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 document or in companion documents in the ISO/TS 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 that are rationally designed with

specific purpose are expected to radically change the landscape in areas such as biotechnology, water
purification and energy development.
The majority of clauses in this document are organized by process type. In Clause 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 grow 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.
In addition, Annex A identifies the processes that are also applicable to macroscopic materials and are
therefore not exclusively relevant to nanomanufacturing. 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.

This document defines terms related to nanomanufacturing processes in the field of nanotechnologies.
All the process terms in this document are relevant to nanomanufacturing, however, many of the listed
processes are not exclusively relevant to the nanoscale. Terms that are not exclusive are noted within
the definitions. Depending on controllable conditions, such processes can result in material features at
the nanoscale or, alternatively, at larger scales.
There are many other terms that name tools, components, materials, systems control methods or
metrology methods associated with nanomanufacturing that are beyond the scope of this document.
Terms and definitions from other parts of the ISO/TS 80004 series are reproduced in Clause 3 for
context and better understanding.
