摘要:
In order to realize a device and a method each capable of forming a lens with high accuracy and low costs, a lens forming device of the present invention includes a metal mold, an insulating substrate, a stage, a power source, a switch, and a UV radiating device. Dielectric resin is supplied onto the insulating substrate and a transfer surface of the metal mold is pressed to the dielectric resin so as to transfer a lens shape to the dielectric resin. At that time, the power source applies a voltage on the metal mold to generate an electric field between the metal mold and the insulating substrate so that an electrostatic attraction causes the dielectric resin to be attracted toward the transfer surface of the metal mold while the top of the dielectric resin has a sharp cuspate shape. Consequently, bubbles are less likely to be invade between the transfer surface and the dielectric resin, allowing transferring a highly accurate lens shape to the dielectric resin.

A liquid discharging nozzle of the present invention includes (i) a liquid reservoir for reserving a discharging liquid and (ii) a discharging tube connected to a bottom part of the liquid reservoir. A water-repellent layer is provided on an inner surface of the discharging tube, on an inner surface of the discharging tube, and on an inner surface of the liquid reservoir, and is a fluorinated water-repellent layer. An aluminum oxide layer and a silicon oxide layer are used as foundation layers of the fluorinated water-repellent layer. The aluminum oxide layer, the silicon oxide layer, and the fluorinated water-repellent layer, which are stacked together, have a combined thickness of not more than 25 nm. The fluorinated water-repellent layer alone has a thickness of 1 nm to 4 nm.
