  • Publication number: 20070071655
    Abstract: The present invention is directed to a semiconductor apparatus that enables in situ wet processing of semiconductor wafers, and prevents creation of a static pressure within the in situ wet processing system. The apparatus comprises multiple exhaust receptacles. Each exhaust receptacle is operable in an open and closed position and receives an associated toxic wet processing byproduct only in the open position. An exhaust is connected to each exhaust receptacle and suctions the contents of said exhaust receptacle in both the open and closed positions. An intake is connected to said exhaust receptacle only when the exhaust receptacle is in a closed position. The intake introduces a gas chemically compatible to the toxic wet processing byproduct associated with the exhaust receptacle. The exhaust releases the toxic wet processing byproduct and the chemically compatible gas to the same waste stream at the semiconductor factory.

  • Publication number: 20060180922
    Abstract: A dielectric material formed by contacting a low dielectric constant polymer with liquid or supercritical carbon dioxide, under thermodynamic conditions which maintain the carbon dioxide in the liquid or supercritical state, wherein a porous product is formed. Thereupon, thermodynamic conditions are changed to ambient wherein carbon dioxide escapes from the pores and is replaced with air.

  • Patent number: 6968577
    Abstract: This is a portable male urinal, which has a separate valve mechanism to prevent the urine from spilling from the device, but also allowing the device to be filled at the appropriate times by moving a handle in a certain direction. It improves the prior art be enabling the user to lock the valve in the “open” position.

  • Publication number: 20050224748
    Abstract: A composition which includes liquid or supercritical carbon dioxide and an acid having a pKa of less than about 4. The composition is employed in a process of removing residue from a precision surface, such as a semiconductor sample, in which the precision surface is contacted with the composition under thermodynamic conditions consistent with the retention of the liquid or supercritical carbon dioxide in the liquid or supercritical state.

  • Publication number: 20050211269
    Abstract: A surface cleaning apparatus comprising a chamber, and a thermal transfer device. The chamber is capable of holding a semiconductor structure therein. The thermal transfer device is connected to the chamber. The thermal transfer device has a surface disposed inside the chamber for contacting the semiconducting structure and controlling a temperature of the semiconductor structure in contact with the surface. The thermal transfer device has a thermal control module connected to the surface for heating and cooling the surface to thermally cycle the surface. The thermal control module effects a substantially immediate thermal response of the surface when thermally recycling the surface.

  • Patent number: 5217929
    Abstract: A foamable lining composition to be used as an expendable lining over a permanent refractory lining in a molten metal handling vessel, e.g. a tundish, comprises a particulate refractory filler material, a binder, a foaming agent and water. Calcined magnesite is the preferred refractory filler material and the binder is preferably an acid phosphate or acid sulphate. The water is included in the composition in an amount of from 5 to 15 per cent by weight.
