Carbon nanotube fabrication versatility is at the heart of innovative new materials growth tool

23.05.2007
Surrey NanoSystems, a joint venture between the University of Surrey’s Advanced Technology Institute and CEVP Ltd, is making its commercial debut at Nanotech 2007, offering what it believes is the most versatile growth tool for carbon nanotube fabrication ever produced, facilitating material growth at 'standard' temperatures in and around the 450-1000 degrees Celsius range, as well as growth at lower temperatures.

Called NanoGrowth 1000n, the new tool is purpose-designed for nanomaterial fabrication and comes with both CVD (chemical vapour deposition) and PECVD (plasma-enhanced CVD) processing capability. These two techniques provide great versatility for users.

Precision fabrication and configuration repeatability principles have been at the core of the tool's architecture, which has been developed by engineers with many years of experience of creating thin-film tools for both scientific research and commercial fabrication. Among the tool's many quality-oriented architectural features are an ultra-high purity gas delivery system and flexible closed-loop control systems that allow users to define target tolerances to achieve a high level of repeatability during all phases of the process.

A very high degree of hardware modularity allows the tool to be expanded easily and configured to meet current and future fabrication requirements. Among many options are further processing techniques such as ICP (inductively coupled plasma), dual sputter sources for catalyst deposition - including a module for delivery of vapour-phase catalysts like ferrocene - plus modules to add process stages for automated pilot production or high throughput. Included in the latter category are an automated wafer transport load/lock system, integrated etching capability, and a PECVD module for deposition of thin-film silicon-based materials.

"This new type of tool addresses the needs of nanomaterial researchers for stable and repeatable results, combined with the flexibility to accommodate individual development ideas. The tool's intrinsic hardware modularity allows users to gain automated control over all aspect of nanomaterial synthesis, from catalyst generation to final material processing," says Dr Guan Yow Chen, Chief Scientist at Surrey NanoSystems.

Users are provided with ready-to-use fabrication programmes. These provide nanomaterial growth 'recipes' in the form of software templates that may be adapted easily by users for their own applications.

Surrey NanoSystems' new carbon nanotube tool is controlled by unique, touch-screen SCADA-style software (supervisory control and data acquisition) – developed and refined over more than seven years on high-end thin-film deposition tools. This software provides an extremely user-friendly interface that sits between the user and the tool - making complex growth or deposition processes both easy to create and run. MIMIC displays of the tool and other graphical techniques provide simple control over all phases of the material growth process, allowing the user to control every aspect - such as gas flow rate, temperatures, RF power, etc – manually or automatically.

Surrey NanoSystems expects the purpose-designed tool to enable nanomaterial researchers to shorten the path to commercialisation. Nanomaterials are expected to have a huge impact on a wide range of next generation technologies such as sensors, interconnects, thermal heat sinks, displays, etc. One of the major goals behind the flexible architecture of the tool is making it possible to commercialise the use of carbon nanotubes and other nanowires in silicon chips - which are approaching their performance limits.

The recipes and patented fabrication technology inside the new tool are field proven, and derived from ground-breaking work by the Advanced Technology Institute (ATI). IP Group Plc provided funding to create Surrey NanoSystems, a corporation dedicated to commercialising the process technology, which was established with staff and intellectual property from ATI and a leading thin-film deposition system manufacturer.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
