Abstract:
An inkjet printing and a micro-pattern manufacturing method using a plasma surface treatment method are provided to exclude the irregularities of the micro-pattern implemented as the ink droplet. A micro-pattern manufacturing method using the inkjet printing and a plasma surface treatment method comprise the step for dry-cleaning a substrate(10); the step for coating the substrate with hydrophobic fluorination organic film(20); the step for heating the substrate(30); the step for forming the micro-pattern on the substrate. The dry-cleaning is performed in the oxygen plasma or ozone generator. The hydrophobic fluorination organic film is formed by using the gas for the semiconductor implantation. The micro-pattern is formed by spraying the ink droplet(1) onto the top of the substrate having the constant temperature.
Abstract:
A fluidic channeling actuator for biochip analysis is provided to control channeling of more than two kinds of sample fluids using electrowetting phenomenon, thereby being very usefully used for analyzing reaction, diffusion and reaction speed of the fluids. A fluidic channeling actuator for biochip analysis comprises: a lower plate(20) having a plurality of microchannels through which fluid and a sample solution are injected; an electrode(30) installed on the lower plate and applied voltage from an external device and a portion of which is placed between the plurality of microchannels, a hydrophilic pattern formed on the upper side of the electrode; a hydrophobic pattern formed on the hydrophilic pattern upper side; an upper plate(10) which is equipped at the upper side of the lower plate to close the microchannel, has a mixture gate to allow the fluid and the sample solution flown in the microchannel to be mixed and is equipped with an inlet(13) to allow the fluid to be injected; and an air vent which is equipped at the upper plate and allows air in the within of the microchannel to be discharged by the fluid flowing in, wherein the hydrophobic pattern becomes hydrophilic by electrowetting phenomenon when voltage is applied to the electrode.
Abstract:
The present invention relates to a print pattern forming method through the control of a position where an ink droplet is dropped and, more specifically, to form an accurate and fine print pattern by controlling the drop position of the ink droplet. The print pattern forming method through the control of a position where the ink droplet is dropped comprises: forming a region to form a hydrophilic region and a hydrophobic region on the surface of a substrate; dropping a plurality of ink droplets at the hydrophilic region; drying the ink droplet dropped on the surface of the substrate wherein the ink droplets dropped at the hydrophilic region in the step of dropping the plurality of the ink droplets are overlapped.
