  • Patent number: 7563323
    Abstract: A substrate treating apparatus is capable of promptly heating substrates after exposure, and avoiding an adverse thermal influence on an exposing apparatus. A developing block includes heating modules for heating exposed substrates. An interface block is interposed between the heating modules and the exposing apparatus to isolate the exposing apparatus from the thermal influence of the heating modules. The interface block has a transport mechanism for transporting the substrates to the heating modules, whereby the exposed substrates are promptly transferred to the heating modules.

  • Patent number: 7525650
    Abstract: A substrate processing apparatus for performing a resist coating process and a development process includes an inspection block for making an inspection on a substrate having undergone the development process. The inspection block has an inspection unit for making a predetermined inspection and a transport robot for transferring a substrate to and from the inspection unit. When a substrate to be inspected is transported to the inspection block, the transport robot transports the substrate to the inspection unit. When a substrate not to be inspected is transported to the inspection block, the transport robot transports the substrate directly to the outlet of the inspection block. At this time, a substrate not to be inspected is allowed to pass a preceding substrate to be inspected, at the inspection block. Thus provided is a substrate processing apparatus capable of improving the transport efficiency, to thereby achieve a higher throughput.

  • Patent number: 7497912
    Abstract: A cell controller controls the operation of a transport robot to keep a substrate belonging to a succeeding lot carried into a heating part in the fourth transport cycle from being transported out of the heating part in the next or fifth transport cycle, thereby preventing interference between the transport of substrates belonging to the succeeding lot and the transport of substrates belonging to a preceding lot. If interference is likely to occur between the transport of the substrates belonging to the succeeding lot and the transport of the substrates belonging to the preceding lot, the cell controller causes the substrates belonging to the succeeding lot not to be transported but to remain in processing units. This allows the transport of the substrates belonging to the succeeding lot in consideration of only the next transport cycle.

  • Publication number: 20090014126
    Abstract: A substrate processing apparatus includes a development part for performing a development process on a substrate after being subjected to exposure and a cleaning part. When the processing time in the development part is shorter than the reference time determined in advance, the development part performs all the process steps for development. On the other hand, when the processing time in the development part is longer than the reference time, the development process is split into a first half process step and a second half process step, and the development part performs a processing including the first half process step and the cleaning part performs a processing including the second half process step. Even if the development process takes a long time, it is possible to prevent deterioration in processing capability of the substrate processing apparatus on the whole by splitting the development process.

  • Patent number: 7317961
    Abstract: A substrate processing apparatus includes a plurality of cells each including a predetermined processing unit, a transport mechanism, and a cell controller. The cell controller independently controls operations in each cell in accordance with transport setting and processing condition setting for each cell described in recipe data determined for each substrate unit to be processed. Because the processing and transport are performed independently of the operations of adjacent cells, substrates belonging to different substrate units are received through a feed inlet or the sane substrate inlet, are processed while being present in the same cell, and are transported to a feed outlet and a return outlet which are different substrate outlets. This allows the presence of different process flows in parallel.

  • Patent number: 7229240
    Abstract: When the processing temperature in a heater should be changed between lots, for example, a foremost substrate in a subsequent lot is transported to a position close to the heater such as a substrate holding part, and is held in standby thereat until adjustment of a processing environment (namely, change of the processing temperature) is completed. The substrate held in standby is thereafter transported to the heater. As compared with the case in which substrates are placed in standby in an indexer, substrates can be fed faster to the heater after change of the processing temperature, thereby suppressing throughput reduction.

  • Patent number: 6937917
    Abstract: Provided is a substrate processing apparatus that can reduce power consumption, while maintaining throughput. In addition to a normal mode in which all units are activated, the apparatus is provided with an energy saving mode that is selectable. When the energy saving mode is selected, only essential units that are requisites for a substrate processing are activated and used in the substrate processing. If it is necessary to increase process efficiency, any additional unit may be activated and used in the processing. During standby, only an essential unit can be activated and the rest is halted, or alternatively, all units may be halted. The transition to the energy saving mode can occur when the standby state continues for a predetermined period of time after the normal mode is selected.

  • Patent number: 5184313
    Abstract: An A-phase pulse (S.sub.A) and a B-phase pulse (S.sub.B) are transmitted from a laser interferometic measuring device to a conversion device (5). When the distance-to-be-measured (l) is increasing, a conversion coefficient (D.sub.R) is added to or subtracted from an initial value in an arithmetic calculator (53) at the rising edge and the trailing edge of the pulses (S.sub.A, S.sub.B). The conversion coefficient has a digital value of M-digits and represents a reference distance .lambda./N, where .lambda. is the wavelength of a laser beam (LB.sub.1, LB.sub.2) employed in the laser measuring machine and M and N are positive integers. A predetermined unit distance in the metric system corresponds to a unit number in the (M+1)-th digit. A distance pulse signal (S.sub.L) is generated in response to a carry signal and a borrow signal from the arithmetic calculator, and is used in expressing a change of the distance in the metric system.
