Abstract

A method for the deposition of a liquid on a substrate provides a liquid reservoir for holding the liquid, a nozzle being connected to the liquid reservoir and having a nozzle opening through which the droplets are ejected, a first electrode being in mechanical contact with the nozzle or the liquid reservoir; and a second electrode being arranged above or below the nozzle. The method comprises the application of a potential difference between the first electrode and the second electrode to generate an electric field at a surface of the liquid in the nozzle. The electric field causes the liquid to bend out of the nozzle so as to form a meniscus and to subsequently eject the liquid in the form of individual droplets or in the form of a continuous or intermittently released jet from the meniscus towards the substrate. The ejected liquid is deposited onto a sessile droplet on the substrate at a volumetric ejection flow rate. The sessile droplet is evaporating at a volumetric vaporization rate, and the volumetric ejection flow rate is chosen such that the sessile droplet is sustained by the ejected liquid.
