IEST has released two landmark documents to support facilities involved in research and production at the nanometer scale:
· Recommended Practice IEST-RP-NANO200.1, Planning of Nanoscale Science and Technology Facilities: Guidelines for Design, Construction, and Start-up
Draft International Standard ISO/DIS 14644 Cleanrooms and associated controlled environments - Part 3: Classification of air cleanliness by nanoscale particle concentration
These new documents reflect the expanding role of IEST and its members in the advancing field of nanotechnology. Details about these documents and other IEST activities in the nano arena can be found by visiting the Nanotechnology Institute on the IEST website.
Nanotechnology facilities are among the most complex in existence and require extremely stringent environmental control. IEST-RP-NANO200.1 addresses the unique considerations facing owners, designers, builders, and users of these high-technology facilities.
"Before this RP, there was not really a design guide for nano facilities," said Ahmad Soueid, Chair of IEST Working Group 200, which developed the RP. "With this RP, we didn't set out to create a document for solutions, because the solutions are unlimited. We wanted to identify potential pitfalls as well as some of the questions that need to be addressed along the way."
Each new nano facility represents a learning experience and this RP is the result of a collaborative effort reflecting the experiences of all the project constituents. Novices and experts alike will benefit from this overview that will take them from the earliest planning stages to start-up, helping to avert potential roadblocks during each project phase.
Controlled environments are critical to research and production at the nanometer scale. The first of the documents developed by ISO Technical Committee (TC) 209 to address the requirements of the field of nanotechnology, this entry in the ISO 14644 series of cleanroom standards covers the classification of air cleanliness by particles (ACP) in terms of concentration of airborne nanoscale particles. For classification purposes, only populations of particles with a lower size limit of 0.1 micrometers (100 nanometers) or less are considered. The classification given in the document is for use mainly in "in operation" states. This classification extrapolates the particulate classification equation specified in 14644-1 Classification of air cleanliness into the nanoscale region.
IEST Nano Facility Resources
IEST is well established as the preeminent technical society in the areas of contamination control; design, test, and evaluation; and product reliability. Several areas of nanotechnology intersect with these fields, and IEST has taken steps to provide related resources.
IEST Working Groups have been established to write Recommended Practices (RPs) related to nanotechnology facilities. In addition to the first published document, IEST-RP-NANO200, a facility-safety document is in development. Topics being explored for future RPs include vibration and acoustics, electromagnetic and radio frequency effects, testing aerosol-nanomaterial containment devices, and others.
A technical session on Fabrication Facility Operations was introduced at ESTECH 2013, the 59th Annual Technical Meeting of IEST, held April 29-May 2, in San Diego, California. This new track was established in response to interest from participants in the biennial University/Government/Industry Micro-Nano (UGIM) Symposium in attending an event during alternate years. Presentations were given on the following topics and may be accessed via the Nanotechnology Institute:
Building a Publicly Funded University Cleanroom
CLEAN: A Holistic (and Agile) Approach to LIMS·
Components of an Effective Emergency Response Team in an Urban University Setting
Multidisciplinary Research Center Infrastructure
Safety, Productivity, and Quality in Semiconductor Manufacture with On-site Hydrogen Production
Laboratory Staff Evaluation Process
Software Solutions for Fabrication Facilities
Towards a Supermassive Research Center: Scaling Rules for Laboratory Operations
In addition, the Journal of the IEST issued a special supplement on micro/nano facilities in March 2013. Articles in this issue include a case study on the design and construction of the Draper Laboratory Microfabrication Center; facilities planning for safety and emergency response; and results of a financial and operational survey of 12 university nanofabrication facilities.
The Nanotechnology Institute is part of the IEST website at www.iest.org and is accessible to everyone.
Founded in 1953, IEST is an international not-for-profit technical society of engineers, scientists, and educators that serves its members and the industries they represent (simulating, testing, controlling, and teaching the environments of earth and space) through education and the development of recommended practices and standards.
IEST is an ANSI-accredited standards-developing organization; Secretariat of ISO/TC 209 Cleanrooms and associated controlled environments; Administrator of the ANSI-accredited US TAG to ISO/TC 209; and a founding member of the ANSI-accredited US TAG to ISO/TC 229 Nanotechnologies.
