  • Publication number: 20090269936
    Abstract: A thermal processing unit of a thermal processor for anti-reflection films includes: a covering nozzle for covering a substrate from above supported by a thermal processing plate and discharging an adhesion enhancing agent to a periphery of a substrate supported by the thermal processing plate; and a vaporization processor for supplying an adhesion enhancing agent in the vapor phase to the covering nozzle. While a substrate placed over the thermal processing plate is being subjected to thermal process, a control part causes the covering nozzle to discharge an adhesion enhancing agent in the vapor phase onto a periphery of a substrate to realize adhesion enhancement process. Thus, the adhesion between a resist coating film and a substrate surface in the periphery of a substrate is enhanced. Further, parallel implementation of thermal process and adhesion enhancement process exerts no influence on throughput.

  • Publication number: 20090253078
    Abstract: A method of processing a substrate includes forming a first layer having a photosensitive response to incident radiation on the substrate, forming a first pattern in the first layer, and exposing the first pattern to ultra-violet radiation. The exposure of the first pattern to ultra-violet radiation increases the resistance of the first pattern to a developer. The method also includes forming a conformal protective layer over the first pattern and at least a portion of the substrate. The method further includes forming a second layer having a photosensitive response to incident radiation over the conformal protective layer and forming a second pattern in the second layer.

  • Publication number: 20090165711
    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.

  • 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: 20090120362
    Abstract: A substrate processing apparatus is configured to provide in series a plurality of processing blocks, each block including a processing unit and a transport robot transporting a substrate. A substrate rest is provided in a connecting portion of adjacent processing blocks. A sensor plate with sensor coils is provided spanning over support pins of the substrate rest. Once a temperature-measurement substrate with temperature-measuring elements, each element formed by connecting a coil to a quartz resonator, is placed on the support pins, a transmitter-receiver transmits transmission waves corresponding to the characteristic frequencies of the quartz resonators to the temperature-measuring elements through the sensor coils. After the stop of the transmission, the transmitter-receiver receives electromagnetic waves from the temperature-measuring elements through the sensor coils, and the temperature computer computes the substrate temperature based on the frequencies of the electromagnetic waves.
