  • Patent number: 6062852
    Abstract: A substrate heat-treating apparatus includes a heat-treating plate, and support pins extending through the heat-treating plate to be vertically movable relative thereto. The support pins support each substrate at a lower surface thereof such that edges of the substrate are at a higher level than a central region of the substrate. This construction facilitates air flows into and out of a space between the lower surface of the substrate and the upper surface of the heat-treating plate when the substrate is vertically moved.

  • Patent number: 6060697
    Abstract: A substrate processing apparatus reduces an instantaneous maximum power consumption at turn-on. Power receiving parts of a plurality of processing units are connected to one end of a turn-on switch respectively through switches. The other end of the turn-on switch is connected to an external power source through a breaker. Timer values are set in advance in the timers, respectively. When the turn-on switch is turned on, the timers turn on the associated switches respectively after times which are defined by the timer values, whereby the processing units are provided with electric power, each with a delay of a constant time.

  • Patent number: 6051101
    Abstract: A unit arrangement part comprises a chemical cabinet on its lowermost part, while coating units for forming a resist film on a substrate and developing units for developing the substrate after exposure are arranged on four corners of an apparatus above the chemical cabinet. Further, multistage thermal processing units for thermal-processing the substrate are arranged on front and rear portions of the apparatus above these wet processing units. A cleaning unit for supplying a cleaning liquid such as pure water and cleaning the substrate is arranged on a front side of the apparatus between the coating units as a substrate processing unit. Thus provided is a substrate processing apparatus having excellent workability in maintenance with a high degree of freedom in arrangement of processing units.

  • Patent number: 5963753
    Abstract: A substrate processing apparatus comprises a first substrate transfer unit having a first transfer path and a second substrate transfer unit having a second transfer path. A spin coating unit and a spin developing unit are arranged along the first transfer path, and a substrate cassette is arranged along the second transfer path. A substrate transport robot of the second substrate transfer unit selectively introduces a substrate received from a substrate transport robot of the first substrate transfer unit in one of external exposure apparatuses arranged on both end portions of the second transfer path, and discharges the substrate from the exposure apparatus for transfering the same to the substrate transport robot of the first substrate transfer unit. Thereby the substrate processing apparatus can avoid or relieve reduction of operational efficiency even if its throughput is different from that of an exposure apparatus.

  • Patent number: 5899663
    Abstract: A modular ceiling fan assembly and system is disclosed in which the functioning components are standardized, including standardized connections for their assembly, and multiple components are provided with a plurality of alternate parts for assembly into a variety of uniquely differentiating configurations, styles and appearance without substantially increasing the cost to the manufacturer. The motor platform, including the motor, shafts, switch housing and electrical components and wiring, are standardized into a single configuration, and the holes for mounting the fan blades on the lower surface and/or upper surface of the rotor have a standardized size and spacing. A modular motor housing is formed from multiple horizontal sections, preferably two or three, with a standardized height to accommodate the common single motor platform. The various sections of the modular motor housing are selected in order to produce a variety of uniquely different appearances.
