Abstract: A semiconductor processing chamber is cleaned by introducing a cleaning gas into a processing chamber, striking a plasma in a remote plasma source that is in communication with the processing chamber, measuring the impedance of the plasma, vaporizing a ruthenium containing deposit on a surface of the processing chamber to form a ruthenium containing gas mixture, and flowing the gas mixture through an analyzer and into an exhaust collection assembly. The measurement of the impedance of the plasma in combination with the ruthenium concentration provides an accurate indication of chamber cleanliness.

Abstract: A substrate on the surface of which the liquid film is formed in a cleaning unit is transported to a freezing unit by a substrate transporting mechanism. The liquid film is frozen in the freezing unit and the volume of the liquid film increases. Accordingly, adhesive forces between the substrate and the particles are reduced and the particles even come to separate from the substrate surface. Then the substrate which has been processed freezing is transported from the freezing unit to the cleaning unit again by the substrate transporting mechanism. In the cleaning unit, a physical and/or chemical cleaning is executed to the substrate, and the frozen film is removed from the substrate surface. Thus, the liquid film formation and the freezing of the liquid film is performed as a preprocessing of the physical and/or chemical cleaning in this way, whereby the particles are removed from the substrate surface efficiently.

Abstract: Pure water dissolving nitrogen gas and containing microbubbles is supplied to a substrate. Since microbubbles are very minute in size and also have the electrostatic property, they can efficiently adsorb particles on the substrate surface or in the pure water. Further, since pure water dissolving nitrogen gas is unlikely to be charged, the pure water itself never carries new particles from each component of the apparatus. These functions allow efficient particle removal from the substrate surface or the liquid.

Abstract: A filling system for a toilet tank prevents continual flow to the tank in the event of a leak from the tank by providing a hydraulically actuated safety valve for halting water flow to the filling valve in the event that the water flow continues for a time longer than an expected time of filling. The safety valve has a valve member connected to a piston mounted in a cylinder defining a first chamber on one side of the piston and a second chamber on the other side. A venturi in the supply duct provides in a low pressure chamber of the venturi a water pressure lower than the supply pipe pressure such that a pressure difference across the piston caused by the difference in pressure between the supply pressure and the low pressure chamber causes the piston to move from the first end toward the second end. A flow control orifice regulates a rate of flow of water such that a time of movement of the piston is greater than an expected time required to fill the toilet tank.
