    摘要: A method suitable for cleaning the interior surfaces of a process chamber is disclosed. The invention is particularly effective in removing silicon nitride and silicon dioxide residues from the interior surfaces of a chemical vapor deposition (CVD) chamber. The method includes reacting nitrous oxide (N2O) gas with nitrogen trifluoride (NF3) gas in a plasma to generate nitric oxide (NO) and fluoride (F) radicals. Due to the increased density of nitric oxide radicals generated from the nitrous oxide, the etch and removal rate of the residues on the interior surfaces of the chamber is enhanced. Consequently, the quantity of nitrogen trifluoride necessary to efficiently and expeditiously carry out the chamber cleaning process is reduced.

    摘要: A valve structure is provided for destroying pressure difference between incoming fluids. The valve body includes two inlet passages and a merging passage that is communicated to an outlet. A pressure-balancing device is mounted in the merging passage and includes a shaft supported by two supports or end closures. Two bladed wheels are mounted to the shaft and may be impacted by the incoming fluids to thereby destroy the pressure difference between the incoming fluids.

    摘要: A pressure difference adjusting device is provided for a valve having a first inlet for a first fluid of a first pressure, a second inlet for a second fluid of a second pressure not equal to the first pressure, and an outlet. The pressure difference adjusting device includes two rotatable elements that are mounted in a meeting area of the incoming fluids. The elements mesh with each other to drive each other when the elements are subjected to impact from the incoming fluids.
