【 摘 要 】

Direct write technology assists the electronic industry in their effort tominiaturize electronic circuits and enhance speed of printing capability. Thetechnology allows printing various patterns without employing a mask or a resistwith an enhanced speed with the aid of computer.This paper describes the current status of the synthesis of conductive inks, akey to success in this technology. There are numerous factors to overcome inmanufacturing inks which meet all the necessary conditions of conductivity,viscosity, and stability. In order to achieve the required conductivity,nano-particles used in the ink have to be made from gold, silver or copper.Inherent problems involved in these metal powders include high melting point,coagulation, impurities, cost, and, in the case of copper, oxidation. Thedirection of research currently being carried out in meeting and overcomingvarious challenges in this technology is reviewed and discussed. Other salientapplications of nano-sized metal powders are also briefly examined.
