  • Patent number: 10121648
    Abstract: A maximum height, that corresponds to a width of a pattern formed on a front surface of a substrate to be processed, is searched among a plurality of maximum heights each being a maximum value of a height of a pattern having a particular width when pattern collapse does not occur. Thereafter, it is determined that whether or not a height of the pattern is greater than the maximum height. In a case where the height of the pattern is greater than the maximum height, a hydrophobizing agent is supplied to the substrate such that a hydrophobized region is formed on a whole tip-side region in a lateral surface of the pattern, and a non-hydrophobized region remains on at least a portion of a root-side region in the lateral surface of the pattern. Thereafter the substrate is dried.

  • Patent number: 6434857
    Abstract: A combination closed-circuit washer and drier apparatus having a washing cycle and a drying cycle. The apparatus comprises a unitary housing having a tub and a tumbler within the tub, the tub also having an air inlet and air outlet which allows air to flow through the tub, wherein air flowing from the air inlet is in communication with the tumbler. The apparatus also includes a desiccant recharging system located within the unitary housing having a entrance and an exit, the entrance coupled to the air outlet and the exit coupled to the air entrance, thus allowing a continuous flow of air through the system. The desiccant recharging system also includes a diverting valve that directs the flow of air primarily through the desiccant system in a closed-loop during the wash cycle. The diverting valve alters the air flow between the washing cycle (desiccant regeneration) to the drying cycle (desiccant water adsorption).

  • Patent number: 6430840
    Abstract: A method of and an apparatus for drying a wafer using the Marangoni effect quickly forms an isopropyl alcohol layer on a cleaning liquid in which the wafer is submerged. The isopropyl alcohol is first heated and then supplied in a fluid state onto the cleaning liquid. The isopropyl alcohol liquid thus diffuses rapidly to form the isopropyl alcohol layer. The wafer is thoroughly dried by removing it from the cleaning liquid through the isopropyl alcohol while only supplying more of the heated nitrogen gas into the ambient above the cleaning liquid.

  • Patent number: 6381872
    Abstract: A mixture of lower alcohols whose mean molecular weight is 46 or less is supplied onto a surface of a semiconductor wafer cleansed with water. With this supply, the amount of alcohols left on the semiconductor wafer which has been dried can be suppressed to 2 ng/cm2 or less, and thus a gate oxide film formed on the semiconductor wafer is prevented from deterioration. As a result, a high yield of semiconductor products can be realized.

  • Patent number: 6161300
    Abstract: An alcohol vapor dryer system includes a vapor generating chamber, a heater, a process chamber, a gas supplier, a drain vessel, and a suction device. The vapor generating chamber of cylindrical shape contains liquid alcohol supplied from an outer source and includes a fan installed above the surface of the liquid alcohol. The heater installed below the vapor generating chamber heats the liquid alcohol contained in the vapor generating chamber at a temperature lower than the boiling point of the liquid alcohol. The process chamber communicates with the vapor generating chamber through a plurality of fluid ducts and includes a body and a cover plate for covering the body. The gas supplier generates heated nitrogen gas and supplies the gas in order to transfer the heated nitrogen gas and the alcohol vapors to the fluid ducts which are connected to the process chamber. The drain vessel communicates with the bottom of the body of the process chamber and also with the bottom of the vapor generating chamber.

  • Patent number: 6012233
    Abstract: When drying of garbage is started, the opening and closing valve 61 is opened, and at the same time the processing tank 21 is heated by the heater 31. Due to the foregoing, temperatures in the processing tank 21 and the heating chamber 30 are raised and water contained in garbage in the processing tank 21 starts evaporating. At a point of time when the heating chamber 30 and the condensing chamber 40 are filled with this steam, the opening and closing valve 61 is closed, and the fan 50 is operated, so that steam in the condensing chamber 40 is cooled and condensed. Therefore, steam generated in the heating chamber 30 flows into the condensing chamber 40, and pressure in the heating chamber 30 becomes negative and the boiling point is lowered. Accordingly, it is possible to evaporate water at a low temperature.

  • Patent number: 5956859
    Abstract: A drying apparatus for processing a surface of a substrate wherein, when a nitrogen gas is fed to a nozzle, a jet of the nitrogen gas spouted through a jet hole is generated. The jet becomes film-shaped and is projected upwardly along an inner surface of a side wall of a processing vessel. Then, the jet is collected into an outside through a suction port formed in an upper portion of the processing vessel. The inner surface of the side wall of the processing vessel is covered with the jet. Therefore, an IPA vapor can be prevented from condensing uselessly on the inner surface. As a result, the IPA vapor is effectively utilized for condensation on a surface of the object to be processed which is mounted on a pan. Thus, defective dryness of the object can be prevented.

  • Patent number: 5950328
    Abstract: A drying equipment includes an equipment body including a vapor bath, carrier for carring a semiconductor wafer, receiver tray, inert gas supply unit, cooling pipe, exhaust unit, transportation unit, control unit, etc. An air supply opening of a blower is opposite to a top opening of the vapor bath. The vapor bath contains an organic solvent therein. A vapor is generated by heating the organic solvent. A vapor phase boundary surface is formed on the boundary between the vapor and air overlying the same. When the wafer at low temperature is put into the vapor bath by means of the transportation unit, the organic solvent vapor condenses on the surface of the wafer. The inert gas supply unit supplies an inert gas to the vapor in the vapor bath. The wafer is pulled up slowly from the vapor by means of the transportation unit, and passes the vapor phase boundary surface on the way.
