  • Patent number: 7406974
    Abstract: A washout container to which are mounted inclined ramps that allow a transit mixer, concrete pumping truck or other concrete handling vehicle to drive up over a portion of the container for dumping excess concrete and washing out waste concrete. The container cross-section may be rectangular to semi-circular, and is preferably fabricated with a steel structure. A watertight latching door assembly is coupled to the container to prevent leakage of collected liquid concrete waste material while allowing solidified concrete materials to be unloaded at a disposal site. The interior of the container is preferably lined with a material to which concrete will not adhere. The liner may be applied as a coating to the interior of the container or as a solid material retained within the container. In this way, solidified waste concrete can be easily removed from the container at the disposal site and preferably crushed for recycling.

  • Patent number: 7404863
    Abstract: A method of thinning a silicon wafer in a controllable cost-effective manner with minimal chemical consumption. The wafer is placed into a process chamber, after which ozone gas and HF vapor are delivered into the process chamber to react with a silicon surface of the wafer. The ozone and HF vapor may be delivered sequentially, or may be mixed with one another before entering the process chamber. The ozone oxidizes the silicon surface of the wafer, while the HF vapor etches the oxidized silicon away from the wafer. The etched oxidized silicon is then removed from the process chamber. As a result, the wafer is thinned, which aids in preventing heat build-up in the wafer, and also makes the wafer easier to handle and cheaper to package. In alternative embodiments, HF may be delivered into the process chamber as an anhydrous gas or in aqueous form.

  • Patent number: 7396418
    Abstract: A process for removing particles from a reticle is described, wherein the process is performed by using a pellicle particle detector (PPD) and a particle removing tool disposed in front of the PPD as well as fixed to the PPD. The particle removing tool includes at least one gas spray member directed toward a surface of the reticle for removing particles. The process includes steps as follows, step (a) loading the reticle into the PPD through the gas spray member to detect whether the reticle has particles thereon; step (b) ejecting the reticle from the PPD; step (c) turning on the particle removing tool as well as going back to step (a) when particles are detected on the reticle, and ending the particle removal process when no particle is detected on the reticle.

  • Patent number: 7314529
    Abstract: A soft spray nozzle discharging a cleaning mist is vertically directed and fixed to an arm. A rinse nozzle discharging rinsing deionized water for suppressing obstruction is vertically fixed to the arm at a prescribed distance from the soft spray nozzle. During cleaning, it follows that both nozzles discharge detergents while keeping relative layout relation. Therefore, the discharged cleaning mist and rinsing deionized water do not interfere with each other before reaching the substrate but the used detergents are entirely horizontally splashed and recovered in a cup. Thus, the cleaning mist is prevented from scattering and adhering to the periphery.

  • Patent number: 7210488
    Abstract: A solids removal system for use in removing sand and silt from well production fluids. The system has a manifold assembly provided with jetting nozzles, which is installed in a liquid and solids-containing vessel, where solids have settled in the walls. The jetting nozzles deliver, in a pre-determined sequence, a solids-dislodging fluid, causing the solids to become suspended in the fluid. The dislodged solids and fluid are then extracted by pump from the vessel and directed to a solid-fluid separator. Solids-free fluid is returned for re-re-circulation through the vessel, while the solids are moved to a containment location.
