Abstract:
1. A particle sprayer for disposing charged particles selectively on a substrate having a plurality of electrodes which comprises a nozzle for spraying charged particles onto the substrate, a conductive stage having a fixed position and serving to hold the substrate onto which charged particles are to be sprayed, a plurality of push-up pins for mounting the substrate on and dismounting the substrate from the conductive stage, a probe for applying a voltage identical in polarity with the charged particles to a plurality of electrodes on the substrate disposed on the conductive stage, and a conductor is electrically insulated from the conductive stage, said conductor being a conductive frame provided with an opening smaller in size than the substrate, being disposed on the top of the substrate disposed on the conductive stage, and being applied a voltage of the same polarity as the charged particle polarity thereto.
