    Abstract: The present disclosure provides a photoresist stripping device and a photoresist stripping method. The photoresist stripping device including a conveyor belt, a liquid storage tank, a filtering device, a lighting device and a stripping tank. Through disposing a metal-organic framework (MOF) material in a filter element, the MOF material is configured to adsorb a dissolved oxygen of the stripping solution in a visible light environment, thereby reducing the difference in oxygen concentration between the inside and outside of the gap, and alleviating hollowing out phenomenon of copper caused by stripping the photoresist of the substrate. Further, when reaching a saturation step, can heat or emit ultraviolet light to release the dissolved oxygen to make the filter material recyclable.

  • Patent number: 8439051
    Abstract: The present invention provides a substrate processing system in which a processing liquid is supplied to a substrate W from a processing nozzle 50a situated above the substrate W so as to process the substrate W, and which makes it possible to prevent unintended dripping of the processing liquid from the processing nozzle. A substrate processing system 20 comprises a processing nozzle 50a capable of supplying a processing liquid to a substrate to be processed, an arm 54 supporting the processing nozzle, and droplet removing nozzles 60, 62 capable of blowing a gas to the processing nozzle. The arm is movable between a processing position and a waiting position, the processing nozzle being above a substrate when the arm is in the waiting position and being outside a substrate when the arm is in the processing position. The droplet removing nozzles are so situated that they are in the vicinity of the processing nozzle when the arm is in the waiting position.

  • Patent number: 8434501
    Abstract: A cleaning system which includes an enclosure and having a door with a transparent window. The door is opened and closed to load and unload products to be cleaned. An operator puck on the outside of the enclosure couples magnetically to another actuator puck on the inside of the enclosure. This coupling allows an operator to move and direct the inside puck to actuate spray or air blast functions, without opening the enclosure. The outside operator puck includes one or more switches which turn on the various electronic components such as the liquid pump, light, or air blast valve. The cleaning system enables a user to efficiently direct cleaning action to parts inside to minimize the cleaning time, and to prevent exposure of chemicals. The cleaning fluid is cycled out of the enclosure continuously, and into a “trap” box, through a pump and back into the cleaner box in a closed loop cycle.
