A method for cleaning a semiconductor wafer according to the present invention includes the steps of: removing particles on a semiconductor wafer with an alkaline chemical solution to clean the wafer; neutralizing a surface charge of the semiconductor wafer with a weak acid cleaning solution; and removing residual metal impurities on the semiconductor wafer with an acid chemical solution to clean the wafer. The surface of the semiconductor wafer is neutralized and the HPM treatment is then performed with the semiconductor wafer having no charge. As a result, the surface of the semiconductor wafer can be made extremely clean without attaching metal impurities thereto. |

An acidic, aqueous cleaning composition comprising a surfactant; up to about 50% of a higher boiling solvent, typically in alkyl ether of an alkylene glycol, said solvent introducing impurities into the composition in an amount and of a nature normally chemically incompatible with oxidizable dye chromophores; a dye in an amount to provide a desired tinctorial value, and oxalic acid or a salt thereof in an amount effective to retard fading of the dye. In another aspect of the invention, the oxalic acid incorporated into compositions containing a solvent, a surfactant, and water, and optionally a dye provides a beneficial cleaning result. In yet another aspect of the invention, the oxalic acid beneficially retards the development of malodors when the compositions of the present invention are contained in a PVC container. Broadly, the incorporation of oxalic acid in said solvent can be employed to neutralize said impurities. |

Separation of dissolved aluminum, copper, and other heavy metals and/or carbonates from sodium hydroxide or potassium hydroxide containing wash solutions utilized during the mechanical cleaning of metal-clad containers, especially bottles. This separation is accomplished by adding calcium compounds and separating off the thereby formed precipitates from the wash solution. The specific calcium compound is added to the wash solution directly in the form of a solid compound. Calcium oxide or calcium hydroxide are preferably used as the calcium compounds, and are primarily added directly to the wash solution as a solid. |

A quick connect-disconnect coupling for fluid lines has a tubular socket as the female member thereof, has a sleeve which encircles and is movable relative to that socket, has a tubular plug as the male member thereof, and has interacting surfaces on that socket and sleeve which readily permit that sleeve to move successively from a plug-unlocking position through a plug-locking position to a fluid-on position. Those interacting surfaces automatically prevent accidental movement of that sleeve back from either that plug-locking position or that fluid-on position to that plug-unlocking position. |
