A method and apparatus for preventing contamination of a substrate or a substrate surface, and particularly relates to prevention of contamination of raw materials, semi-finished products, base materials of products and substrate surface in a high-tech industry such as an in the production of semiconductors and liquid crystals. A gas coming into contact with a base material or substrate is purified by dust removing apparatus and adsorption and/or absorption apparatus so that the concentration of fine particles in the gas is below class 1,000 and a non-me...


The invention claimed is: 1. A method for cleaning a substrate placed in a housing, which comprises the following steps: passing a gas supplied to the housing through an absorber and/or absorber for decreasing concentrations of non-methane hydrocarbons therein; passing the treated gas through a dust removing means to remove fine particles contained in the gas; and introducing the gas into the housing in which the substrate is placed. 2. The method of claim 1, wherein the absorber and/or absorber, and the dust removing means remove fine particles in t...
