Viscous substance discharging method using a viscous substance dispenser and pattern forming method using a viscous substance dispenser

摘要

A viscous substance dispenser is provided with a container containing a viscous substance having a viscosity in the range of 1,000 to 1,000,000 cps. The container is provided with a circular orifice or a polygonal orifice of a diameter in the range of 50 mum to 1 mm in its lower portion. An electrode is formed in a portion or the entire portion of the container. A meniscus of the viscous substance is made to bulge out from the orifice and a high voltage pulse is applied to the electrode to pull out the viscous substance through the orifice and a portion of the viscous substance pulled out of the orifice is cut and is made to adhere to a medium.
