    摘要: A process of cleaning the interior of a semiconductor substrate containing metallic impurities therein is provided. The semiconductor substrate is heated, with one side or the both sides thereof being in contact with a melt of a metal or an inorganic salt, at a high temperature such that the melt does not react with these semiconductor and the semiconductor is not melted. By this process, the impurities present inside the substrate are removed out of the substrate and the interior thereof is cleaned.

    摘要: A polishing apparatus is used for chemical mechanical polishing a copper (Cu) layer formed on a substrate such as a semiconductor wafer and then cleaning the polished substrate. The polishing apparatus has a polishing section having a turntable with a polishing surface and a top ring for holding a substrate and pressing the substrate against the polishing surface to polish a surface having a semiconductor device thereon, and a cleaning section for cleaning the substrate which has been polished. The cleaning section has an electrolyzed water supply device for supplying electrolyzed water to the substrate to clean the polished surface of the substrate while supplying electrolyzed water to the substrate.

    摘要: A wafer dry cleaning method and apparatus capable of eliminating or suppressing adhesion of dust and particles on dried wafer surfaces while minimizing generation of water marks thereon. To achive this, the wafer dryer apparatus is configured including a surface cleaning/drying chamber structure which houses therein a set of spaced-apart silicon wafer workpieces. The dry chamber is operatively associated with a vacuum evacuation device for retaining the interior of this chamber at low pressures required. A water-drain device is provided for forcing water content separated off from the wafer surfaces to drain out of the drying vessel. During such wafer drying process, the wafers may be driven rotating at high speeds to thereby accelerate centrifugal spin-off of residual drops of water on wafer surfaces. Preferably, a chosen purge gas may be fed into the chamber during wafer rotation. The purge gas supply gets started substantially simultaneously upon activation of a vacuum pump for chamber evacuation, or after completion of such vacuum evacuation. In one illustrative embodiment ultrapure water may be used to rinse the wafers in the chamber.

    摘要: In the etching method, ozone water containing an oxidation agent having an oxidation-reduction potential of 2V or more is supplied onto a metal compound film such as SrRuO film or the like, and the metal compound film is etched by oxidation-reduction reaction involving oxygen. The metal compound film, which is conventionally removed by a physical removal method, can be easily removed by wet etching. Manufacture of a capacitor containing an SrRuO film and the like can thus be facilitated.

    摘要: There is proposed an apparatus and method for cleaning a semiconductor substrate, which make it possible to minimize the adhesion of mist in a cleaning tank at the occasion of cleaning a semiconductor substrate, to realize a high removal effect of residual polishing particles, and to enable to obtain a clean surface. In view of preventing a mist generated by the jet of high pressure water from re-adhering to the substrate during the cleaning of a semiconductor substrate, a cover member is disposed at a mist-generating region so as to prevent the splash of the mist. Additionally, a cavity is caused to generate by contacting a high pressure water with a still water, and high-frequency generated by the generation of the cavity is utilized for removing the residual polishing particles. Alternatively, the ejection of high pressure water against the surface of the substrate is performed in a liquid phase such as ultrapure water, thereby preventing the generation of mist.
