  • Patent number: 6929985
    Abstract: A material not releasing gaseous organic substances during use is used as a filter medium and a sealing material for tightly sealing between the medium and a frame. Specifically, a synthetic paraffin not containing an aliphatic hydrocarbon having not more than 19 carbon atoms or less is used as a non-silicone type water repellent contained in a treatment agent for forming fibers into a cloth-like filter medium. A carboxylic acid ester having 400 or more molecular weight is used as a plasticizer and a phenolic compound having 300 or more molecular weight is used as an antioxidant to be added to the treatment agent and the sealing material. This enables that the gaseous organic substances are not present in a clean room, a semiconductor production apparatus or the like.

  • Patent number: 6929672
    Abstract: The present invention has as its object to provide an air filter not only for trapping suspended particulate substances but also for not generating hazardous contaminates in the air, which cause trouble in the manufacture of semiconductor devices. As a binder to bind fibers of the air filter together, a polymer dispersion is used in which a copolymer of a hydrophilic monomer and a hydrophobic monomer is dispersed in water. As an initiator for polymerization of the copolymer, an organic peroxide is used. When an air filter (8) is installed downstream of a chemical filter (7), the space (4) placed downstream of the air filter (8) is made substantially free of organic substances and/or inorganic substances that cause trouble in the manufacture of semiconductor devices.
