  • Publication number: 20240157391
    Abstract: Proposed is a substrate treating apparatus. The substrate treating apparatus includes a treating container having a treating space therein, a support unit supporting and rotate a substrate in the treating space, and a liquid supply unit supplying a treating liquid onto the substrate, wherein the liquid supply unit may include a nozzle member and an actuator for moving the nozzle member, wherein the nozzle member may include nozzles arranged along a first direction so that the nozzles form a first row and nozzles coupled to the body and arranged along the first direction so that the nozzles form a second row, wherein the first row and the second row may be spaced apart from each other in a second direction perpendicular to the first direction when viewed from above. At this time, the nozzles constituting the nozzle member may be observed as a whole from the front.

  • Patent number: 8113141
    Abstract: In a substrate-processing apparatus for performing coating, baking and developing processes on a semiconductor substrate, a first processing block performs a coating process and a developing process. A second processing block is disposed opposite to the first processing block to heat-treat substrates. A main transfer block is disposed between the first and second processing blocks to transfer the substrates. A third processing block is disposed on one side of the main transfer block in a direction perpendicular to an arrangement direction of the first and second processing blocks to adjust a temperature of the substrates. An auxiliary transfer block is disposed adjacent to the second and third processing blocks to transfer the substrates between the second and third processing blocks. Thus, an overload of the main transfer block may be reduced.

  • Patent number: 8115142
    Abstract: In a plate for adjusting a temperature of a substrate, a body of the plate supports the substrate. A first channel and a second channel are disposed within the body of the plate. The first channel has a first inlet and a first outlet and passes therethrough a first fluid to adjust the temperature of the substrate. The second channel has a second inlet adjacent to the first outlet and a second outlet adjacent to the first inlet and passes therethrough a second fluid to adjust the temperature of the substrate. Further, the first and second channels are disposed side by side. Thus, the temperature of the substrate may be adjusted uniformly as a whole.
