Abstract:
Disclosed is a substrate treating apparatus. The substrate treating apparatus includes a housing having a space for treating a substrate in the interior thereof, a spin head which supports and rotates the substrate inside the housing, and an ejection unit having a first nozzle member for ejecting a first treatment liquid onto the substrate positioned on the spin head. The first nozzle member includes a body having an ejection passage, through which the first treatment liquid flows, therein and a first discharge hole communicated with the ejection passage to eject the first treatment liquid onto the substrate, and a vibrator installed in the body to provide vibration for the first treatment liquid flowing through the ejection passage. The vibrator has an interference preventing recess for preventing an interference by reflective waves therein.
Abstract:
An apparatus for treating a substrate includes a process chamber having a treatment space defined therein, a support unit for supporting the substrate in the treatment space, a fluid supply unit for supplying supercritical fluid to the treatment space, and a controller configured to control the fluid supply unit, wherein the fluid supply unit is configured to selectively supply the supercritical fluid at a first density or a second density higher than the first density into the treatment space. Thus, drying efficiency of the substrate when drying the substrate using the supercritical fluid may be improved.
Abstract:
Disclosed is a nozzle for supplying a treatment liquid to a substrate, the nozzle including a body having a passage, through which the treatment liquid flows, in the interior thereof, and having a discharge hole communicated with the passage and through which the treatment liquid is discharged, and a piezoelectric element that pressurize the treatment liquid flowing through the body to discharge the treatment liquid through the discharge hole in a state of droplets, wherein an average diameter of the droplets discharged through the discharge hole is equal to or greater than 5 micrometers and is less than 15 micrometers.
Abstract:
A substrate treating apparatus and a substrate treating method are provided. The substrate treating apparatus includes a first process chamber to apply an organic solvent to a substrate applied with a developer and introduced, and a second process chamber to treat the substrate applied with the organic solvent and introduced, through a supercritical fluid.
Abstract:
An apparatus for supplying chemical liquid may include at least two ink jet heads, a reservoir for receiving a chemical liquid provided onto a substrate from each of the at least two ink jet heads, a chemical liquid for supplying member providing the chemical liquid to each of the at least two ink jet heads, and a chemical liquid collecting member for drawing and collecting a chemical liquid remained in each of the at least two ink jet heads. One path of the chemical liquid from the chemical liquid supplying member to the chemical liquid collecting member via one of the at least two ink jet heads may be substantially the same as a length of another path the of chemical liquid from the chemical liquid supplying member to the chemical liquid collecting member via the other of the at least two ink jet heads.
Abstract:
A nozzle for supplying a fluid to a substrate, the nozzle including a body having a liquid discharge line through which the liquid flows and a gas discharge line that surrounds the liquid discharge line and through which a gas flow, wherein the body includes a plurality of liquid discharge holes that discharge the liquid flowing through the liquid discharge line, and a gas discharge hole that discharges the gas flowing through the gas discharge line.
Abstract:
Disclosed is an apparatus and method for treating a substrate. The method includes supplying cleaning particles to the substrate to clean the substrate. The cleaning particles are solid particles. The solid particles provide a shock wave to the substrate.
Abstract:
A substrate processing apparatus includes a chamber including an upper chamber and a lower chamber coupled to each other to provide a space for processing a substrate, a substrate support configured to support the substrate within the chamber, an upper supply port provided in the upper chamber and configured to supply a supercritical fluid on an upper surface of the substrate within the chamber, a recess provided in a lower surface of the upper chamber, the recess including a horizontal extension portion extending in a direction parallel with the upper surface of the substrate in a radial direction from an outlet of the upper supply port and an inclined extension portion extending obliquely at an angle from the horizontal extension portion, and a baffle member disposed within the recess between the upper supply port and the substrate.
Abstract:
Disclosed is a method of treating a substrate. In one embodiment, supercritical fluid is supplied to a treatment space in a chamber such that the substrate in the treatment space is treated. The supercritical fluid is supplied to the treatment space while exhausting the treatment space. A temperature of the supercritical fluid supplied when exhausting the treatment space is higher than a temperature of the supercritical fluid supplied to the treatment space for treating the substrate.
Abstract:
An ink tank for a liquid chemical discharging apparatus capable of preventing equipment failure and improving durability by preventing scattering and backflow of a liquid chemical. To this end, the present invention provides an ink tank for a liquid chemical discharging apparatus including: a liquid chemical receiving portion in which a liquid chemical is stored; a liquid chemical discharge port supplying the liquid chemical to an inkjet head; a pressure control port for controlling pressure of the liquid chemical receiving portion; and a partition wall which is provided in the liquid chemical receiving portion to partition the liquid chemical receiving portion. According to the present invention, it is possible to prevent contamination due to a liquid chemical by suppressing the liquid chemical from sloshing and improve durability of an ink tank by preventing the liquid chemical contained therein from flowing backward out of the ink tank.
