Abstract Laser sintering of interconnects printed on flexible substrate with silver nanoparticle ink is studied as an alternative to convection oven sintering. Interconnects of 80 μm and 250 μm line width are printed using an aerosol jet printer and sintered using an 830 nm continuous wave laser. A conductivity that is 4.5× higher than that of an oven sintered interconnect is achieved at optimal laser power and sintering speed set using a full factorial statistical design.

Gold Microstructures

Employing the fountain pen principle, a micropipette is used to write an Au nanoparticle ink on glass substrates. A continuous-wave laser (488–515 nm) is subsequently used as a controlled, localized energy source to evaporate the carrier liquid (toluene) in the ink and sinter the nanoparticles together thus fabricating continuous gold stripes 5 micrometers in width and a few hundred nanometers in height. The scanning speed, the laser intensity, and the degree of defocusing are identified as important parameters to the successful manufacturing of the gold microstructures. The electrical resistivity of the stripes, within the parametric domain of the present work, is measured to be the order of 10−6 ohm-m.
