Abstract:
An aspect of this disclosure is a substrate treatment method of performing a treatment for forming a pattern of a metal-containing resist on a substrate includes changing an acid concentration in a substrate existence space where the substrate exists in a substrate treatment apparatus before a developing treatment of a film of the metal-containing resist.
Abstract:
A liquid treatment apparatus includes: a substrate holder for holding a substrate; a discharge nozzle for discharging a treatment liquid onto the substrate; a liquid supply pipe for supplying the treatment liquid from a treatment liquid storage source to the discharge nozzle; a gas pipe that encompasses the liquid supply pipe and through which an inert gas for adjusting the temperature of the treatment liquid flows in a space between the gas pipe and the liquid supply pipe; a processing container in which the substrate holder, the discharge nozzle, the liquid supply pipe, and the gas pipe are provided; and an atmosphere gas supply part for supplying an atmosphere gas into the processing container. The gas pipe is provided so that an extension portion between an upstream end inside the processing container and an encompassing portion is folded back inside the processing container in a plan view.
Abstract:
A technique for suppressing a metal component from remaining at a bottom of a mask pattern when the mask pattern is formed using a metal-containing resist film. A developable anti reflection film 103 is previously formed below a resist film 104. Further, after exposing and developing the wafer W, TMAH is supplied to the wafer W to remove a surface of the anti-reflection film 103 facing a bottom of the recess pattern 110 of the resist film 104. Therefore, the metal component 105 can be suppressed from remaining at the bottom of the recess pattern 110. Therefore, when the SiO2 film 102 is subsequently etched using the pattern of the resist film 104, the etching is not hindered, so that defects such as bridges can be suppressed.
Abstract:
A substrate treatment method includes: a polymer separation step of phase-separating a block copolymer into a hydrophilic polymer and a hydrophobic polymer; and a polymer removal step of selectively removing the hydrophilic polymer from the phase-separated block copolymer, wherein in the polymer removal step, the hydrophilic polymer is removed by: irradiating the phase-separated block copolymer with an energy ray; then supplying a first polar organic solvent having a first degree of dissolving the hydrophilic polymer, being lower in boiling point than water and capable of dissolving water, and not dissolving the hydrophobic polymer, to the block copolymer; and then supplying a second polar organic solvent having a second dissolving degree lower than the first dissolving degree, being higher in boiling point than water, and not dissolving the hydrophobic polymer, to the block copolymer.
Abstract:
A substrate processing method includes: forming a coating film on a substrate by supplying a resist liquid which is photosensitive to extreme ultraviolet (EUV) light to a surface of the substrate; forming a semi-solidified film by volatilizing a solvent contained in the coating film without heating the solvent; irradiating the semi-solidified film with EUV light thereby exposing the semi-solidified film with EUV light; and supplying a developer to the substrate after the exposure of the semi-solidified film.

Abstract:
There is provided a method of processing a substrate using a block copolymer composed of a first polymer containing an oxygen atom and a second polymer containing no oxygen atom, the method including: coating the block copolymer onto the substrate on which a predetermined pattern is formed; phase-separating the block copolymer into the first polymer and the second polymer; and heating the substrate in a low oxygen atmosphere to selectively remove the first polymer from the phase-separated block copolymer.
