In this paper, we demonstrated the continuous wave (CW,1064nm) laser sintering of nano-sliver electrode patterns printed by an aerosol jet printer on polyethylene terephthalate (PET) substrate. A laser sintering apparatus has been constructued which has precise control of laser spot size to 15um and can effectively minimize the damage of substrates and other functional layer in multilayer devices. The effects of the laser processing parameter on the sintering results including scanning speed and power were investigated. The electrical resistivity of laser sintered nano-silver electrode was measured to be 2.4 × 10 -6Ωm which is similar to that achieved in conventional oven sintering.
