Abstract: A method and a system for providing event information to targeted parties based on a determination that the targeted parties are likely to have a high level of interest in the respective events are provided. The method includes: receiving information that relates to an event; retrieving, from a memory, information that relates to a user; analyzing the event-related information and the user-related information; determining, based on a result of the analysis, an interest level of the user with respect to the event and whether to recommend that the user attend the event; and generating and transmitting a message to the user that includes at least part of the event-related information. The analysis may be performed by applying an artificial intelligence (AI) algorithm that is trained by using the user-related information and uses a natural language processing (NLP) technique to analyze the event-related information and the user-related information.

Abstract: System, including methods, apparatus, and kits, for bone fixation using a fixation device including a mounting portion and a fastener that attaches to the mounting portion. In some embodiments, the fixation device may include first and second mounting portions configured to be disposed across a bone from each other and secured with a fastener that extends from one of the mounting portions, through the bone, and to the other mounting portion. The system also may include a tool to facilitate installation of the fixation device.

Abstract: A electromagnet array structure including multiple electromagnetic coils captured in a rigid encapsulant, for example, of cured epoxy resin, to form a unitary free-standing structure which can be placed around the walls of a plasma processing chamber. A liquid cooling coil may also be captured in the encapsulant between the electromagnetic coils. The structure may additionally include water fittings, locating pins, through tubes for chamber bolts, and lifting brackets.

Abstract: A quadruple electromagnetic coil array coaxially arranged in a rectangular array about a chamber axis outside the sidewalls of a plasma sputter reactor, preferably in back of an RF coil within the chamber. The coil currents can be separately controlled to produce different magnetic field distributions, for example, between a sputter deposition mode in which the sputter target is powered to sputter target material onto a wafer and a sputter etch mode in which the RF coil supports the gas sputtering the wafer. The coil array may include a tubular magnetic core, particularly useful for suppressing stray fields. A water cooling coil may be wrapped around the coil array to cool all the coils. The electromagnets can be powered in different relative polarities in a multi-step process.

Abstract: A multi-step process performed in a plasma sputter chamber including sputter deposition from the target and argon sputter etching of the substrate. The chamber includes a quadruple electromagnetic coil array coaxially arranged in a rectangular array about a chamber axis outside the sidewalls of a plasma sputter reactor in back of an RF coil within the chamber. The coil currents can be separately controlled to produce different magnetic field distributions, for example, between a sputter deposition mode in which the sputter target is powered to sputter target material onto a wafer and a sputter etch mode in which the RF coil supports the argon sputtering plasma. A TaN/Ta barrier is first sputter deposited with high target power and wafer bias. Argon etching is performed with even higher wafer bias. A flash step is applied with reduced target power and wafer bias.
