摘要:
A syringe for dispensing liquid materials to a substrate. In one embodiment, the syringe includes a barrel having a first end, a second end, and an interior reservoir. A piston is slidably disposed within the reservoir and is movable to increase or decrease a volume of the interior reservoir near the first end of the barrel. A first end of the piston has a hemispherically-shaped surface profile, with an elongated apex extending therefrom, to dispense liquid from the first end of the barrel when the piston is moved in a direction toward the first end.
