  • Patent number: 12217989
    Abstract: A semiconductor apparatus and a method for collecting residues of curable material are provided. The semiconductor apparatus includes a chamber containing a wafer cassette, and a collecting module disposed in the chamber for collecting residues of curable material in the chamber. The collecting module includes a flow-directing structure disposed below a ceiling of the chamber, a baffle structure disposed below the flow-directing structure, and a tray disposed on the wafer cassette. The flow-directing structure includes a first hollow region, the baffle structure includes a second hollow region, and the tray is moved together with the wafer cassette to pass through the second hollow region of the baffle structure and is positioned to cover the first hollow region of the flow-directing structure.

  • Publication number: 20240387215
    Abstract: A method for collecting residues of curable material includes: performing a curing process on a semiconductor wafer in a chamber, where the semiconductor wafer is held by a wafer cassette, and residues of curable material is formed in the chamber; and collecting the residues of curable material. A first portion of the residues dripping from a ceiling of the chamber is directed toward a tray using a flow-directing structure, where the flow-directing structure is below the ceiling of the chamber, the flow-directing structure includes a central opening and a slanted surface sloped to direct the first portion of the residues toward the central opening. The first portion of the residues is collected on a collecting surface of the tray which covers the central opening of the flow-directing structure.
