    Abstract: After rinsing, a liquid mixture (IPA+DIW) is supplied to a substrate surface while rotating a substrate at a first rotating velocity which is relatively high to thereby replace the rinsing liquid adhering to the substrate surface with the liquid mixture. In this way, the rinsing liquid adhering to the gaps between the patterns formed on the substrate surface is replaced with the liquid mixture. Subsequently, DIW is supplied to the substrate surface in a condition that the rotation of the substrate is stopped or that the substrate is rotated at a second rotating velocity which is relatively low to thereby form a puddle-like liquid layer with DIW. In this way, the liquid mixture of the surface layer part is removed from the substrate surface while leaving almost all the liquid mixture adhering to the gaps between the patterns. After that, the liquid layer is removed from the substrate surface to thereby dry the substrate surface.

  • Patent number: 6742285
    Abstract: An air knife constructed in accordance with the present invention directs a curtain of air across a region and most typically is used to direct the stream of air against a surface. In an exemplary embodiment of the invention the air knife includes an elongated housing having an inlet for receiving air into the housing. The housing includes an elongated gap that extends along the housing that allows air entering the housing through the inlet to exit the housing and form a curtain of air. The elongated housing is made from a piece of sheet metal bent to define a hollow region into which air is forced. The sheet metal defines a gap along a length of the housing from which the air exits. The elongated air knife forms an angle with respect to a direction of travel of glass sheets passing the air knife so that a leading edge of those glass sheets passes progressively different parts of the air knife.

  • Patent number: 6735883
    Abstract: Apparatus and a method for enhancing the effectiveness of a water spray (30) to cool and/or remoisten a web (12) of material. The apparatus includes a web dryer, preferably a flotation dryer (100), an electrostatic charge generating device (31) or devices, a water spray (30), an integrated power supply (20) to supply high voltage power to the charge device, and a drainage system (35) for handling excess liquid generated during the cooling and/or remoistening of the web. The cooling apparatus is capable of a modular arrangement to optimize spacing and facilitate the addition of cooling capacity where needed, such as with faster web speeds or heavier web weights. One or more temperature sensors can be used to optimize the amount of and rate of fluid fed to the spray nozzles. The spray nozzles and charge bars can be retractable with respect to the web to facilitate web-up procedures.

  • Publication number: 20040050517
    Abstract: The invention relates to a method in a paper or board machine, in which method water is removed from a paper or board web (W) by pressing in a press section (30), in which pressing stage the web (W) is pressed in at least one press nip (35; 36), and in which method the web (W) is dried after pressing by impingement drying, in which method the web (W) is passed as a closed draw from the press section (30) to a dryer section (40), and the method applies full-width threading from the press section (30) to the dryer section (40). The web (W) is dried by impingement drying by means of impingement units (46) placed around at least one large-diameter impingement roll (45). In the method, the web (W) is passed after impingement drying as a closed draw through the dryer section (40) to a calender (60), and in the method threading is accomplished as of full width through the dryer section (40).

    Abstract: An apparatus for performing contaminant sensitive processing on a substrate. A substrate load chamber receives the substrate from an ambient contaminant laden environment, and isolates the substrate from the ambient contaminant laden environment. The substrate load chamber further forms a first environment of intermediate cleanliness around the substrate. A substrate pass through chamber receives the substrate from the substrate load chamber, and isolates the substrate from the intermediate cleanliness of the first environment of the substrate load chamber. The substrate pass through chamber further forms a second environment of high cleanliness around the substrate. A substrate transfer chamber receives the substrate from the substrate pass through chamber, and isolates the substrate from the high cleanliness of the second environment of the substrate pass through chamber.

  • Publication number: 20030061730
    Abstract: A substrate feed chamber that is equipped in a substrate processing apparatus is provided. The substrate feed chamber has a storage tray capable of storing simultaneously three or more substrate holding trays that hold substrates in a vertical or substantially vertical condition and a horizontal movement mechanism that moves horizontally the storage tray with respect to the substrate feed position in order to effect feeding-in or feeding-out movement of the substrate holding tray between any of the chambers of a group consisting of processing chambers and load lock chambers and, in addition, if required, has a rotary movement device that rotates the storage tray. Improvement in throughput in a substrate processing apparatus can thereby be achieved and increase in the ground-contacting area of the device as a whole can be prevented.
