  • Publication number: 20140285549
    Abstract: A liquid supply apparatus includes a reservoir for storing a liquid therein, a supply path for supplying the liquid from the reservoir to a liquid consuming apparatus, a pump for feeding the liquid from the reservoir to the supply path, and a controller for outputting a driving signal to the pump to control the supply of the liquid. The controller acquires a target feed volume of the liquid from the pump to gradually change a feed volume of the liquid from the pump from a current feed volume to the target feed volume, based on a request signal from the liquid consuming apparatus serving as a destination to which the liquid is supplied. This suppresses an abrupt change in pressure in the liquid consuming apparatus serving as the destination to which the liquid is supplied.

  • Publication number: 20140273498
    Abstract: In a substrate processing apparatus, provided are an upper nozzle for supplying a chemical liquid having a temperature higher than that of a substrate onto an upper surface of the substrate and a heating liquid supply nozzle for supplying a heating liquid having a temperature higher than that of the substrate onto a lower surface of the substrate. It is thereby possible to suppress or prevent a decrease in the temperature of the chemical liquid supplied on the upper surface of the substrate from a center portion of the substrate toward an outer peripheral portion thereof. In a supply nozzle, the heating liquid supply nozzle is positioned on the inner side of a heating gas supply nozzle for ejecting heating gas in drying the substrate. It is thereby possible to simplify and downsize a structure used for heating the lower surface of the substrate.

  • Publication number: 20140261557
    Abstract: In a substrate processing apparatus, an ejection surface of an ejection head located at a standby position is immersed in an immersion liquid retained in a reservoir during standby of the ejection head. This prevents drying of a plurality of outlets provided in the ejection head and drying of processing liquid flow passages that communicate with the outlets. It is thus possible to suppress or prevent clogging of the fine outlets. When the ejection head resumes processing on a substrate, the immersion liquid in the reservoir is discharged and then a liquid removing part removes the immersion liquid adhering to the ejection surface. Accordingly, it is possible to prevent the immersion liquid remaining on the ejection surface from dropping and adhering to the substrate (so-called “liquid dripping”) when, for example, the ejection head is moved to a position above the substrate.

  • Publication number: 20140267495
    Abstract: An inkjet printer includes a cleaning unit to be brought into contact with a head lower surface of an ejection head, and a unit movement mechanism for moving the cleaning unit. The cleaning unit includes a base part, a cleaning liquid ejecting part protruding above the base part, and a pair of positioning parts. The positioning parts are brought into contact with a block lower surface of a head fixation block on opposite sides of the cleaning liquid ejecting part to keep an under-head gap for holding the cleaning liquid between the cleaning liquid ejecting part and the head lower surface. Since the positioning parts are spaced from the cleaning liquid ejecting part, it is possible to prevent the cleaning liquid that has spread from the under-head gap to the surrounding area from adhering to the block lower surface via the positioning parts.

  • Publication number: 20140261586
    Abstract: In a substrate processing apparatus, an election head from a position above a substrate held by a substrate holding part to an inspection position above a standby pod disposed outside a cup part. At the inspection position, a processing liquid ejected from the ejection head toward the standby pod is irradiated with planar light emitted from a light emitting part. An imaging part acquires an inspection image including bright dots appearing on the processing liquid, and a determination part determines the quality of the ejection operation of the ejection head on the basis of the inspection image. Accordingly, it is possible to eliminate the influence of reflected light from the substrate and droplets, mist, or the like of the processing liquid having collided with the substrate and to accurately determine the quality of the ejection operation of the ejection head.

  • Publication number: 20140270734
    Abstract: Four wafer pins are fixed in a chamber and spaced at intervals of 90 degrees. Four support pins are provided in a wafer pocket of a susceptor and spaced at intervals of 90 degrees. The four wafer pins and the four support pins are disposed concyclically in an alternating manner at intervals of 45 degrees. When halogen lamps irradiate a semiconductor wafer with light to heat the semiconductor wafer, the susceptor is moved upwardly and downwardly, so that the semiconductor wafer is shifted between the wafer pins and the support pins. This eliminates the occurrence of a problem such that the quartz pins which are relatively low in temperature are continuously kept in contact with particular places of the semiconductor wafer to improve the uniformity of the in-plane temperature distribution of the semiconductor wafer.

  • Publication number: 20140261577
    Abstract: An ejection inspection part of a substrate processing apparatus includes a light emitting part and an imaging part. The light emitting part emits light along a predetermined light existing plane to irradiate a processing liquid ejected from outlets of an ejection head with the light. The imaging part captures an image of the processing liquid passing through planar light emitted from the light emitting part to acquire an inspection image including bright dots. In the ejection inspection part, a determination frame setting part sets normal ejection determination frames corresponding to the outlets in the inspection image. The determination part acquires existence information indicating whether or not a bright dot exists in each normal ejection determination frame and uses the existence information to determine the quality of the ejection operation of the outlet corresponding to the normal ejection determination frame.

  • Publication number: 20140267490
    Abstract: In an inkjet printer, a cap part for receiving ink from a head unit during maintenance includes a liquid receiving part and an exhaust part disposed laterally to the liquid receiving part. In the liquid receiving part, a second liquid receiving chamber is disposed further from the exhaust part than is a first liquid receiving part. A second flow path is disposed below the first liquid receiving chamber without passing through the first liquid receiving chamber. In the exhaust part, a first fan part is connected to the first liquid receiving chamber, and a second fan part is connected to the second liquid receiving chamber through the second flow path. Accordingly, it is possible to appropriately exhaust a gas contained within the second liquid receiving chamber, independently of the first liquid receiving chamber. Consequently, a mist in the liquid receiving part can be discharged efficiently.

  • Patent number: 8835813
    Abstract: A light-emission output of a flash lamp for performing a light-irradiation heat treatment on a substrate in which impurities are implanted is increased up to a target value L1 over a period of time from 1 to 100 milliseconds, is kept for 5 to 100 milliseconds within a fluctuation range of plus or minus 30% from the target value L1, and is then attenuated from the target value L1 to zero over a period of time from 1 to 100 milliseconds. That is, compared with conventional flash lamp annealing, the light-emission output of the flash lamp is increased more gradually, is kept to be constant for a certain period of time, and is then decreased more gradually. As a result, a total heat amount of a surface of the substrate increases compared with the conventional case, but a surface temperature thereof rises more gradually and then drops more gradually compared with the conventional case.
