    摘要： This invention relates to a method of manufacturing a semiconductor device having elements isolated by a trench. A trench is formed to surround an element region of a silicon substrate by anisotropic etching. A nonoxide film such as a silicon nitride film is selectively formed on the upper surface of the element region. Thermal oxidation is performed using the nonoxide film as a mask to form an oxide film on the inner face of the trench and the upper surface of a field region. Thereafter, a polysilicon layer is buried in the trench, and after the surface of the polysilicon layer is flattened, a capping oxide film is formed on the upper surface of the trench. In addition, a non-oxide film is formed to have an interval between the end of the nonoxide film and the trench of 2 .mu.m or more.

    摘要： A double side cleaning apparatus includes a pair of roll-like brushes and at least one cleaning brush. The roll-like brushes are driven to rotate in opposite directions, and a semiconductor wafer is arranged between them in a non-contact manner. The cleaning brush is arranged near the pair of roll-like brushes. While the semiconductor wafer is arranged between the pair of roll-like brushes and its upper and lower surfaces are being cleaned, the cleaning brush brushes the side surface of the semiconductor wafer. A cleaning agent is supplied from the pair of roll-like brushes to the semiconductor wafer to clean it. Since the upper and lower surfaces of the semiconductor wafer are cleaned in a non-contact manner, dust can be removed efficiently (within a short period of time and a small space).

    摘要： A method of reducing the concentration of metal ions in pure water or ultrapure water and thereby obtaining pure water or ultrapure water. Such purified pure water or purified ultrapure water is used, for example, when washing semiconductor wafers, as a starting material of electrolytic ionic water, or for diluting washing water. A pair of carbon electrodes is disposed in an ultrapure water storage tank containing pure water or ultrapure water or in a purifying tank disposed in a line leading from an ultrapure water storage tank. A D.C. voltage is applied across the electrode pair. A carbon electrode material having a large specific surface area is chosen, and an electrode structure with which there is little detachment of carbon fragments is used. After the carbon electrode is molded, a carbon layer is formed on the surface of the molding by dipping the molding in an amorphous carbon bath. Because the carbon layer penetrates into the pores in the molding surface, the bonds between the carbon elements are strengthened, preventing carbon fragments from detaching. Because the electrode surfaces may be covered with filters, even if carbon fragments do detach, they are caught by the filters, preventing particles from entering the purified pure water or purified ultrapure water.
