  • Patent number: 9063429
    Abstract: After a developing step, a substrate is spun at high speeds without supplying a cleaning liquid to a surface of the substrate. This causes a large centrifugal force to act on a developer on a resist film. Consequently, the developer can be removed rapidly from the surface of the substrate. As a result, development can be stopped at an expected timing. Moreover, a circuit pattern having an expected dimension can be obtained. At this time, a dissolved product is also removable with the developer from the substrate. This can avoid failure in development caused by the dissolved product. Consequently, suitably maintained quality of negative development can be achieved with a reduced usage amount of the cleaning liquid.

  • Publication number: 20140342558
    Abstract: A treating section has substrate treatment lines arranged one over the other for treating substrates while transporting the substrates substantially horizontally. An IF section transports the substrates fed from each substrate treatment line to an exposing machine provided separately from this apparatus. The substrates are transported to the exposing machine in the order in which the substrates are loaded into the treating section. The throughput of this apparatus can be improved greatly, without increasing the footprint, since the substrate treatment lines are arranged one over the other. Each substrate can be controlled easily since the order of the substrates transported to the exposing machine is in agreement with the order of the substrates loaded into the treating section.

    Abstract: A substrate treating apparatus includes a plurality of substrate treatment lines arranged vertically. Each substrate treatment line has a plurality of main transport mechanisms arranged horizontally, and a plurality of treating units provided for each main transport mechanism for treating substrates. A series of treatments is carried out for the substrates, with each main transport mechanism transporting the substrates to the treating units associated therewith, and transferring the substrates to the other main transport mechanism horizontally adjacent thereto. The substrate treating apparatus realizes increased processing capabilities by treating the substrates in parallel through the substrate treatment lines.

  • Publication number: 20140120477
    Abstract: A method of processing a substrate in a substrate processing apparatus that is arranged adjacent to an exposure device and includes first, second and third processing units, includes forming a photosensitive film on the substrate by said first processing unit before exposure processing by said exposure device and applying washing processing to the substrate by supplying a washing liquid to the substrate in said second processing unit after the formation of said photosensitive film and before the exposure processing. The method also includes applying drying processing to the substrate in said second processing unit after the washing processing by said second processing unit and before the exposure processing and applying development processing to the substrate by said third processing unit after the exposure processing. Applying the drying processing to the substrate includes the step of supplying an inert gas onto the substrate, to which the washing liquid is supplied.

  • Patent number: 8708587
    Abstract: The invention provides coating units, heat-treating units, and a first main transport mechanism for transporting substrates to each of these treating units. The substrates are transferred from the first main transport mechanism to a second main transport mechanism through a receiver. When a substrate cannot be placed on the receiver, this substrate is placed on a buffer. Thus, the first main transport mechanism can continue transporting other substrates. The other substrates in the treating units are transported between the treating units without delay, to receive a series of treatments including coating treatment and heat treatment as scheduled. This prevents lowering of the quality of treatment for forming film on the substrates.

  • Publication number: 20110170855
    Abstract: A joint nozzle that delivers a developer, a rinsing liquid and nitrogen gas is disposed adjacent the spin center of a substrate in plan view. A controller operates electromagnetic switch valves to continue supply of the developer, while spinning the substrate, in a developing process, and to start supply of the rinsing liquid in a rinsing process, immediately after the supply of the developer ends, thereby achieving a shortened period of the developing process. A switching is made to a drying process by starting supply of the nitrogen gas immediately after completion of the rinsing process. Thus, even if the substrate has a large angle of contact, formation of droplets of the rinsing liquid is inhibited to prevent post-develop defects.
