    摘要: Ozonizer (10) which supplies a feed gas to ozone generating cell (11) under application of a high voltage and which delivers an ozone gas through an ozone gas transport path (consisting of pipes (14) and (15)) as it has been generated in said ozone generating cell (11) is characterized in that the ozone gas transport path is furnished with means for removing at least one of NOx, HF and SOx (in the drawings, the means is for removing NOx) and that the ozone gas from the ozone generating cell (11) is passed through said removing means, whereby at least one of NOx, HF and SOx in said ozone gas is removed before it is delivered to a subsequent stage. The product ozone is not contaminated with Cr compounds at all or insufficiently contaminated to cause any practical problems in the fabrication of highly integrated semiconductor devices. Alternatively, ozonizer (10) which comprises an ozone generating cell (11) having an inlet (8) for supplying a feed gas, high voltage applying means (35) and an outlet (29) for discharging the ozone generated, and ozone delivery paths (30) and (31) for delivering the generated ozone is characterized in that oxygen (1) supplemented with 10 - 20 vol% of carbon dioxide and/or carbon monoxide (2) is used as the feed gas. The thus produced ozone is significantly low in the level of Cr compounds and, hence, can suitably be used in the formation of metal oxides, in particular, silicon oxide.

    摘要: In an improved ozonizer, at least those parts of an ozone gas delivery path located downstream of an ozone generating cell which are to come into contact with ozone gas are either composed of or coated with at least one ozone-resistant, Cr-free material selected from among aluminum (Al), an aluminum alloy, Teflon, fluorinated nickel, a nickel alloy, a silicon oxide based glass and a high-purity aluminium oxide. The ozonizer is capable of producing ozone that is not contaminated with Cr compounds at all or which is insufficiently contaminated to cause any practical problem in the fabrication of highly integrated semiconductor devices.

    摘要: In an electric discharge type ozonizer using highly pure oxygen gas having a purity of not lower than 99.99% as a raw material gas, the pressure of a gas in the discharge space of a discharger is raised to a level higher than atmospheric pressure by at least 1.1 kgf/cm² and/or in which a liquid-cooled discharger is used, and the temperature of the cooling liquid is set at a level not lower than 15°C, whereby the ozonizer is capable of stably producing ozone gas at a high ozone concentration without causing lowering of the ozone concentration with time.

    摘要: An ozone generator comprises a pair of spaced opposing electrodes, electrically conductive members connecting the pair of electrodes to a high-voltage alternating-current power source to generate an electric discharge between the electrodes, a dielectric provided between the opposing electrodes, and a gas flow passage for effecting flow of a material gas defined by the surfaces of the electrodes. At least one of the surfaces of the pair of electrodes has a plurality of parallel grooves. The material gas flows in a space between the plurality of grooves and the dielectric, in a direction transverse to the grooves.
