This work explores a method to construct metal-coated carbon nanotube (CNT) structures, which are potential candidates for interconnects, transmission lines and contact structures. This simple method is suitable to many applications including flexible substrates. In this work, electroplating is used to coat a carbon nanotube surface with Indium. CNT films are prepared using drop casting method on different substrates: Ni coated silicon wafer, copy paper and photo paper. The CNT dispersion used for this work is prepared using sonication and centrifugation with a surfactant. The resulting dispersion has 0.8 wt. % of multi-walled CNTs and 0.5 wt. % of sodium dodecyl sulfate (SDS) in DI water. This dispersion is modified to reduce resistivity by adding either silver nanoparticle powder or silver ink. Electroplating is done at room temperature with a current density of 0.02 A/cm2. This work addresses two issues about electroplating on CNT: low electrical conductivity of CNT film and low CNT adhesion to substrate. A CNT film on a Ni surface displays poor adhesion; the film peels off easily during ultrasonication and electroplating. After thermal annealing or microwave treatment, adhesion between the CNT film and Ni is greatly enhanced such that no CNT film peel-off is observed during electroplating. A CNT film on paper has a high sheet resistance. As a result, Indium is only plated on the CNT film near the attached electrode. To reduce the film sheet resistance, the CNT solution is modified by adding silver nanoparticle powder or silver ink. Ethanol rinsing is also performed on the CNT film surface to wash away surfactant and further reduce sheet resistance. On-going work involves ink-jet printing of CNT solutions onto flexible substrates. Indium, as an example metallization, will be plated on these ink-jet printing defined transmission lines and interconnects patterns. Performance of these structures will be presented.

The Individual

Over the last decades ink-jet-printing has developed in many applications. The di-rect writing of materials such as silver (for conductive circuits) or polymers (for insulation or second layer) is an attractive method to reduce costs and save raw materials. For conductor paths silver inks with nanoparticles are used. To ensure a good dispersion the nanoparticles are mostly covered with organic compounds. To guarantee electrical conductivity the organic compounds have to be removed and the particles have to be sintered to minimize resistivity. This is done by heating up the silver structures. In this article we compare different meth- ods of sintering conductive paths printed using a silver ink with a particle size of ≤ 50 nm. The methods of sintering are the established thermal sintering in an oven, and alternatively laser sintering as well as electrical resistive sintering. Laser sintering is carried out with a semiconductor laser with a wavelength of 408 nm and different feeding speeds so the energy input in the structures can be varied. For electrical resistive sintering a DC-current is injected to the structures whereby they are heated up by the current. During electrical sintering the actual value of the resistance of the hot structures can be observed. Thereby the sintering can be stopped, when a certain value (of the hot structure) is reached. The best parameters for both sintering alternatives are identified. The conductivity and the deviation of the conductivity of the sintered paths are determined and compared with the results achieved for thermal sintering. As a result, it can be stated, that both alternatives pro-vide specific advantages over thermal sintering such as lower deviations of the measured values or significantly lower process times. On the other hand, specific limitations might occur when using laser or electrical sintering. Additionally, the individual amount of energy input for the three respective sintering pro-cesses is calculated and compared with each other to determine the most energy efficient sintering method. Also the process of direct contacting electrical devices with ink-jet-printing is compared with the standard process wire bonding related to the consumption of material and energy.
