A syringe delivery system for dispensing a highly viscous material through a syringe delivery opening. Means for solving A composition for forming a topcoat layer, comprising a solvent and a fullerene derivative having a hydrophilic group; and also a method of forming a pattern by casting the above composition on a resist surface and then by subjecting it to exposure and development. The current limiter circuit includes an interface for coupling to the current loop, and a current source element coupled to the process control equipment. As well, manufacturing costs are diminished by eliminating the UBM between the chip pad and the RDL pattern.
