  • Publication number: 20090142162
    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: 20070183775
    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.

  • Patent number: 7105074
    Abstract: A substrate treating apparatus is provided for eliminating wasteful consumption of a treating solution in a treating mode in which the treating solution is delivered in a strip form to a substrate from a treating solution delivery nozzle sweeping over the substrate. In a first aspect of the invention, collecting vessels are arranged around a developing cup surrounding a wafer supported by a wafer holder. The collecting vessels collect part of a developer delivered from a discharge opening of a developer delivery nozzle outwardly of a surface of the wafer. In a second aspect of the invention, collecting vessels are arranged below a developer delivery nozzle, with collecting openings of the collecting vessels opposed to a discharge opening or openings of the delivery nozzle. The collecting vessels are moved longitudinally of the discharge openings according to a position of the developer delivery nozzle relative to the wafer.

  • Publication number: 20060147201
    Abstract: An interface transport mechanism employs an upper hand during the transport of a substrate to an exposure device, and employs a lower hand during the transport of the substrate that has been carried out of the exposure device. A fifth central robot employs a lower hand during the transport of a substrate after the exposure processing by an exposure device, and employs an upper hand during the transport of a substrate after the drying processing that has been carried out of a drying processing group. That is, the upper hand is employed to transport a substrate to which no liquid is attached, and the lower hand is employed to transport a substrate to which a liquid is attached after the exposure processing.

  • Patent number: 6963789
    Abstract: A controller is connected to a substrate processing apparatus and an exposure apparatus. A pilot substrate subjected to a series of processing as preprocessing is transported to an inspection unit. An inspection result determination part compares inspection results received from the inspection unit with substrate condition data so that a condition change instruction part changes the processing condition of each processing unit when no requirement is satisfied. This operation is so repeated that a processing control part executes actual processing according to recipe data when the inspection results satisfy the requirement. Thus, the efficiency a step of changing the processing condition of each processing part in response to the inspection results in the inspection part is improved in preprocessing executed in the substrate processing apparatus.

  • Patent number: 6832863
    Abstract: A series of substrate transport paths for transporting substrates is arranged on upper and lower stories. Substrates are transferable between the substrate transport path on the first story and the substrate transport path on the second story. The paths include a going-only path for transporting the substrates forward, and a return-only path for transporting the substrates in the opposite direction, these paths being arranged on the upper and lower stories. An indexer connects one end of the substrate transport path on one story to one end of the substrate transport path on the other story. An interface connects the other end of the substrate transport path on one story to the other end of the substrate transport path on the other story. This construction efficiently reduces a waiting time due to interference between the substrates transported along the going-only path and the substrates transported along the return-only path.
