ABSTRACT:
A method for depositing controlled quantity of particles on a substrate comprises providing aerosolized particles in a deposition zone having first and second electrodes, and creating an electrostatic field between the first electrode and the second electrode to create a pool of ions at the first electrode, charging particles within the deposition zone with the ions, and moving the particles towards and depositing the particles onto the substrate. In order to prevent excessive charge build up on the substrate, the electrostatic field is periodically reversed.
