    摘要: An improved gas injection assembly for mounting in a central bore of a dielectric window of an inductively coupled plasma chamber includes a window having a central bore and cylindrical recess configured to receive an annular insert having a bayonet opening. The gas injector assembly includes a gas injector, an RF shield surrounding the gas injector, and a faceplate surrounding the RF shield, the faceplate including projections at the bottom thereof for engaging the bayonet opening in the annular insert. The window and gas injection assembly are designed to avoid chipping of the window which is typically made of quartz and in prior mounting arrangements the window has a bayonet opening machined therein. Due to the brittle nature of the quartz material, the machined bayonet opening was subject to chipping when the gas injector assembly was inserted into the bayonet opening.

    摘要: The present invention discloses an inductively coupled coil and an inductively coupled plasma device using the same. The inductively coupled coil comprises an internal coil and an exterior coil which are respective from each other and coaxially arranged, internal coil comprising a plurality of internal respective branches having the same configurations which are nested together, the plurality of internal respective branches being arranged symmetrically with respect to an axis of the inductively coupled coil; the to external coil comprising a plurality of external respective branches having the same configurations which are nested together, the plurality of external respective branches being arranged symmetrically with respect to the axis of the inductively coupled coil. The inductively coupled coil is located on the reaction chamber of the inductively coupled plasma device and is connected to a RF source. It can make the plasma distribute uniformly on the wafer in the reaction chamber so that the difference in chemical reaction rate on the surface of the wafer is small and the quality of the etched wafer is improved. They can be applied in a semiconductor wafer manufacturing apparatus, and they can also be adapted to other apparatuses.

    摘要: A method for treating a nonhomogeneous material surface of an object is provided. A plurality of test patches of the surface is treated for different amounts of time wherein the plurality of test patches have a total surface area. A property of each test patch is measured. A calibration curve of the property is generated with respect to time. The calibration curve and a target property are used to obtain a target time. A surface of the object with a surface area, which is greater than the total surface area of the plurality of test patches, is treated for the target time.
