  • Publication number: 20080288217
    Abstract: The invention relates to the acquisition of log data in an apparatus such as a substrate processing apparatus. The invention permits detailed data related to a premonitory phenomenon preceding the occurrence of an alarm condition to be acquired without increasing the amount of data. A data logging method of the invention has a constitution wherein a difference between the maximum value and the minimum value of the acquired data is determined, wherein a first segment of the acquired data is stored if the difference is not less than a preset value, and if the difference is less than the preset value, a second portion included in the first segment of the acquired data is stored.

  • Patent number: 6742977
    Abstract: An unprocessed substrate is conveyed to a film-processing chamber at the same time a processed substrate is conveyed to a substrate preparation chamber, reducing the substrate processing cycle, thereby increasing the yield per unit time. The substrate preparation chamber has a two-tiered structure for receiving processed substrates and unprocessed substrates. A two-tiered transfer robot allows the substrates to be removed or placed into the preparation and process chambers at the same time, thus decreasing the cycle time for processing a substrate.

  • Publication number: 20010035124
    Abstract: Throughput is increased, the footprint is reduced, heating may be carried out in a short time, and variations in the temperature of the substrate surface may be reduced. A heating chamber 47 for heating the substrate is formed as an upper level of a load/lock chamber 13, and a cooling chamber 48 for cooling the substrate is formed as a lower level of the load/lock chamber 13. An upper heater 51 and a lower heater 56 are formed above and below the heating chamber 47. A shower plate 52 is located between the upper heater 51 and the lower heater 56. A gas heating space 50 is located between the upper heater 51 and the shower plate 52. An N2 gas introducer 42 is connected to the gas heating space 50, such that N2 gas is introduced into the gas heating space 50. The N2 gas introduced from the N2 gas introducer 42 is heated in the gas heating space 50 and is then supplied to the substrate W in the form of a shower via the shower plate 52.

  • Patent number: 5957651
    Abstract: A rotary shaft is supported by a frame so as to be rotatable and movable vertically relative to the frame. A carrying arm is pivoted to the rotary shaft and a substrate receiver is attached to an end of the carrying arm and receives a substrate. A guide base is mounted on the rotary shaft on the lower side of the substrate receiver in such a manner that the guide base is approximately parallel to the substrate receiver, and a substrate alignment mechanism is attached to the rotary shaft via the guide base. The substrate alignment mechanism includes a pair of location correcting members which are coupled to air cylinders. The location correcting members are displaced by air cylinders to correct the location of substrate.

  • Patent number: 5850071
    Abstract: A substrate heating equipment for use in a semiconductor fabricating apparatus includes a heater support frame disposed within a vacuum vessel, opposed panel heaters disposed in a pluri-shelved fashion within the heater support frame, and support means for supporting a substrate to be treated between an adjacent pair of the opposed panel heaters, whereby simultaneous heating of plural substrates to be treated is enabled. By controlling the individual temperature of the panel heaters, it also becomes possible to significantly reduce a tact time and to effect uniform heating of the substrates while the equipment is rendered compact.
