Abstract

The Laser Ablation of Microparticle Aerosol (LAMA) process provides a method for generating high yields of aerosolized nanoparticles (NP). The NP are accelerated through a nozzle and impacted onto substrates to produce films or patterned lines. Using the LAMA process, we have demonstrated the ability to produce thick films and lines from a variety of pure metals, compounds and alloys. The resulting lines and films offer a significant reduction in the post-processing temperatures required to densify the lines/films compared to conventional processes for producing patterned lines such as screen printing. This is demonstrated for Ag lines used to produce seals at low process temperatures.
