NEC Corporation today announced the successful development of a carbon nanotube (CNT) transistor using a coating process. The basic operation of the new transistor with advanced characteristics has been verified, confirming its application in the printed electronics field.
Main features of the new CNT transistors:
The demand for electronics has rapidly increased in recent years along with environmental concern. This has brought about the need for more advanced electronic products that simultaneously achieve reduced environmental impact.
Organic transistors and other printed electronics are one potential solution to this problem. Printed electronics' technologies are unique in that they allow transistors to be formed by printing directly onto the substrate. This means that manufacturing processes can be dramatically simplified in comparison to conventional semiconductors; waste materials generated through manufacturing processes can be reduced, and CO2 emissions can be reduced by more than 90%.
The channel materials of conventional research organic transistors generally demonstrate little mobility and are therefore considered unsuitable for electronic devices with high-speed operation. The basic operations for a transistor formed using this coating process were confirmed for the newly developed CNT transistor, which adopts CNTs as its channel material to allow 100 times greater mobility than regular organic transistors. The research results prove the potential of CNTs as a core transistor material, even in the field of printed electronics. Further research is expected to show the potential to dramatically expand the scope of printed electronics applications.
The results of this research will be presented at "nano tech 2008 International Nanotechnology Exhibition & Conference" being held at Tokyo Big Sight from February 13 to 15.

At the GSMA Mobile World Congress AMD announced an expanded portfolio of products and technologies to enable such popular, media-rich applications as mobile TV, 3D games and high-fidelity audio, delivering immersive entertainment to tomorrow's mobile phones and handheld devices.
AMD has enhanced its line of innovative, open-standard handheld device technologies with upcoming AMD Imageon processors, as well as next-generation 3D and vector graphics cores available for licensing. These new AMD offerings are designed to allow device manufacturers and network operators to support today's most popular applications, as well as cutting-edge applications that will thrill tomorrow's mobile consumer.
The latest technology offerings to broaden the popular family of AMD Imageon processors will include:
Graphics To Go AMD is committed to delivering graphics to consumers everywhere by licensing intellectual property (IP) to mobile chipset suppliers. AMD announced several IP deals during the past year as part of this business. Building on that success, next-generation AMD graphics cores are available to leverage the same AMD technology that provides graphics platform from PCs to game consoles such as the Microsoft Xbox 360 video game and entertainment system.
New AMD handheld technology will be available for OEMs and silicon supplier licensees to sample beginning this month. Features enabled by these new products and technologies are expected to start appearing in mobile devices in late 2008 and 2009.
