Abstract: An aluminum nitride-based sintered body is disclosed, which includes aluminum nitride as a main ingredient and magnesium and has a polycrystalline structure composed of aluminum nitride crystals.
Abstract: The invention is embodied in a coil antenna for radiating RF power supplied by an RF source into a vacuum chamber, the coil antenna including plural helical conductors each having a first end and a second end, the first ends being adapted for connection to a first common RF potential, the second ends being adapted for connection to a second common RF potential, each of the plural conductors being wound about a common axis of helical symmetry, each of the second ends being spaced substantially equally from the axis and from each other.
Abstract: The invention is embodied in an antenna for radiating RF power supplied by an RF source into a vacuum chamber, the antenna including plural concentrically spiral conductors, each having a first end located in a first common region and a second end located in a second common region, and each being wound about a common axis passing through both regions, the regions being concentric with the axis, the conductors being substantially the same length, substantially the same shape, and substantially evenly spaced with respect to each other about the common axis.

Abstract: An inductive plasma torch operating at atmospheric pressure is used for wafer or glass substrate processing. Said torch employs a linear type of plasma confinement. This linear torch is particularly suitable for photoresist etching and processes in which it has the advantages of high chemical isotropic etch rate and low plasma damage.
