摘要： A method and apparatus for forming a semiconductor device. A semiconductor substrate is implanted with dopants. The substrate is subjected to a cleaning process employing electrically neutral nitrogen and fluorine radicals to produce an oxygen-free surface having dangling bonds. Before any further exposure to oxidizing gases, the substrate is annealed by thermal treatment to activate and distribute the dopants. A gate oxide layer is formed over the annealed surface. The apparatus performs all such treatments without breaking vacuum.

摘要： The invention concerns high sensitivity light scattering detection and its application to evaporative light scattering detection in liquid chromatography. The exemplary embodiment includes a detection cell to accept particles suspended in a gas stream and permit a polarized light beam to pass through a trajectory of the particles and gas stream. A sample light detector is disposed to detect light scattered in the detection cell. A light trap accepts the polarized beam after it passes through the detection cell. The light trap includes an elongated housing through which the polarized beam passes, and light absorptive material within the elongated housing. An absorptive filter is aligned such that the angle of incidence of the light beam upon the filter approximates Brewster's angle and the electric field vector of the beam is aligned with the plane of incidence between the beam and the filter. Other embodiments of the invention provide increased light collection. Embodiments of the invention include temperature-controlled entrance and exit ports that control particle trajectory. Embodiments of the invention include a reference cell disposed between a detection cell and a light trap, and the reference cell includes lensing and a spherical mirror to direct light toward a reference light detector. The reference light detector provides a reference signal that may be used with noise cancellation circuitry, operating in either voltage or current mode, to reduce light source noise in the sample signal.

摘要： An appparatus for confining plasma within a process zone of a substrate processing chamber. In one aspect, an apparatus comprises an annular member having an upper mounting surface, an inner confinement wall, and an outer confinement wall. The apparatus is disposed on or otherwise connected to a gas distribution assembly of the processing chamber to prevent plasma edge effects on the surface of a substrate. The apparatus provides a plasma choke aperture that reduces the volume of the process zone around the periphery of the substrate thereby eliminating uneven deposition of material around the edge of the substrate.

摘要： A composite structure comprising a layer of zeolite having a high silica to alumina ratio supported on a support layer acts as a separator in a redox flow battery. The zeolite can be either supported on a rigid substrate, such as alumina, or a flexible substrate, such as a polymeric film. The polymeric film, in particular, can be an ion exchange membrane such as Nafion. The zeolite layer with a high silica to aluminum ratio provides a long-lasting separator for redox flow batteries.

摘要： A focused droplet nebulizer of the invention produces substantially uniform droplets of a predetermined size. Droplets are pushed out through a small outlet orifice by the contraction of a chamber. The droplets can be carried on a substantially non-divergent path in a drift tube. A piezo membrane micro pump acts in response to an electrical control signal to force a droplet out of the outlet orifice. The nebulizer can operate at frequencies permitting a stream of individual droplets of the predetermined size to be sent along the substantially non-divergent path in the drift tube in a preferred embodiment ELSD device.
