An electrodischarge apparatus has a nozzle that includes a discharge chamber that has an inlet for receiving a liquid and an outlet. The apparatus has a first electrode extending into the discharge chamber that is electrically connected to one or more high-voltage capacitors. A second electrode is proximate to the first electrode to define a gap between the first and second electrodes. A switch causes the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes from the nozzle ahead of the plasma bubble.

The present inventions relate to the formation of a thin polymer film on a substrate. Apparatus is described for transforming a solid polymer resist into an aerosol of small particles, electrostatically charging and depositing the particles onto a substrate, and flowing the particles into a continuous layer. Apparatus is further described for transforming solid resist into an aerosol of small particles by heating the resist to form a low viscosity liquid such as is compatible with nebulization and applying the techniques of jet or impact nebulization and aerosol particle sizing to form the aerosol. A method is further described of using ionized gas to confer charge onto the aerosol particles and using a progression of charging devices establish an electric field directing the flow of charged particles to the substrate. The progression of charging devices and associated apparatus results in high collection efficiency for the aerosol particles.
