NEC Succeeds in Fabrication of CNT Transistor Using Coating Process

Tokyo, February 13, 2008 - 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
(1) Based on an NEC device model, design guidelines were established to verify the relationship between transistor characteristics and the length and density of the CNT when the CNT channel is created and to increase CNT transistor performance.
(2) A channel coating-process technology, capable of accurately controlling the density of the CNT, was also developed. CNT transistors were produced based on the new design guidelines and technology. Despite performance variation, extremely high mobility - the speed at which electrons move in the material - for a transistor manufactured using this type of coating process was achieved
