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.

Abstract: A foam mat with a differently colored border includes an upper layer and a lower layer overlaid with the upper layer. The upper and lower layers are made of foaming materials of different colors, and each peripheral side of the foam mat is processed into an inclined edge where the lower layer extends further outward than the upper layer. The inclined edges show differently colored layers which are both easily identifiable and esthetically pleasing. The inclined edge at each peripheral side of the foam mat also provides a slope which reduces the chance of a user's feet hitting the foam mat by accident when the user is stepping on the foam mat.

Abstract: An exercise soft pad with ventilation includes a pad body made of a foam material. The pad has a pad surface for its user to exercise thereon. The pad surface has several vent holes going through the pad body. Therefore, the hot air produced by the user exercising thereon can go out through the ventilation holes.
