METHOD AND APPARATUS FOR APPLYING A MATERIAL ON A SUBSTRATE

摘要

The invention provides a method for applying a material onto a substrate using a droplet printing technique wherein a gas stream is released into the direction of a substrate, which gas stream comprises a carrier gas and droplets of a suspension of the material or droplets of a solution of a precursor of the material or droplets of a precursor of the material as such, whereby the droplets in the gas stream are first maintained in a steady flow and subsequently in a converging flow before the droplets are contacted with the substrate. The invention further provides an apparatus for carrying out said method.
