Key words: carbon nanotubes, integrated circuit

Carbon nanotube devices and integrated circuits because of the speed, power consumption advantages, is considered to be the future most likely to replace silicon integrated circuits, continue Moore theorem of information technology is one of the device. After nearly 20 years of research, preparation of carbon nanotubes in device physics, electronics components and optimizing, simple integrated circuit has made rapid progress and system demonstration.

However, limited by materials and processing technology, the preparation of carbon nanotube transistor size, yield and uniformity is always difficult to reach a higher level, limiting the carbon nanotubes to the industrialization development of integrated circuit technology further.

In recent period, with support from the Beijing municipal science and technology commission, Beijing university professor peng lian spear team on how to make carbon nanotubes from transistor to the worldwide problem of the research of system of integrated circuits, made significant progress. Team through the device of carbon nanotubes material, size and structure, to optimize the preparation technology, implements the yield 100% of the carbon nanotube transistors batch preparation, the use of the material preparation of transistor is close to the commercial 65 nm node of the silicon CMOS transistor level; The carbon nanotubes containing 140 transistors is prepared four full adder circuit and two multiplier circuit, is currently the highest level of integration and complexity in the world the strongest carbon nanotubes integrated circuit, the circuit that successful development of carbon nanotube technology already have the ability to produce large scale integrated circuit, will greatly accelerate the practical process of carbon nanotube integrated circuit.
