摘要： A method for patterning a magnetic thin film on a substrate includes: providing a pattern about the magnetic thin film, with selective regions of the pattern permitting penetration of energized ions of one or more elements. Energized ions are generated with sufficient energy to penetrate selective regions and a portion of the magnetic thin film adjacent the selective regions. The substrate is placed to receive the energized ions. The portion of the magnetic thin film is subjected to thermal excitation. The portions of the magnetic thin film are rendered to exhibit a magnetic property different than selective other portions. A method for patterning a magnetic media with a magnetic thin film on both sides of the media is also disclosed.

摘要： A method for defining magnetic domains in a magnetic thin film on a substrate, includes: coating the magnetic thin film with a resist; patterning the resist, wherein areas of the magnetic thin film are substantially uncovered; and exposing the magnetic thin film to a plasma, wherein plasma ions penetrate the substantially uncovered areas of the magnetic thin film, rendering the substantially uncovered areas non-magnetic. A tool for this process comprises: a vacuum chamber held at earth potential; a gas inlet valve configured to leak controlled amounts of gas into the chamber; a disk mounting device configured to (1) fit within the chamber, (2) hold a multiplicity of disks, spacing the multiplicity of disks wherein both sides of each of the multiplicity of disks is exposed and (3) make electrical contact to the multiplicity of disks; and a radio frequency signal generator electrically coupled to the disk mounting device and the chamber, whereby a plasma can be ignited in the chamber and the disks are exposed to plasma ions uniformly on both sides.

摘要： A system for supplying processing fluid to a substrate processing apparatus having walls, the inner surfaces of which define a processing chamber in which a substrate supporting susceptor is located. The system consists of a number of fluid storages, each which stores a separate processing fluid, at least two fluid conduits along which processing fluid flows from the fluid storages to the processing apparatus and a fluid inlet which connects the fluid conduits to the processing chamber. The inlet has a separate fluid passage, corresponding to each of the fluid conduits, formed along it. Each fluid passage opens at or near an inner surface of a wall to define a fluid mixing zone, so that fluid moving along one fluid passage is prevented from mixing with fluid moving along any other passage until reaching the mixing zone.

摘要： A barrier to prevent reactant gases from reaching the surfaces of a susceptor support for a substrate upon which polysilicon films are to be deposited provides improved uniformity of the depositing film across the substrate, and prevents substrate-to-substrate variations during sequential depositions. A suitable barrier includes a preheat ring extension that mates with an extension of the susceptor support.

摘要： Thin, uniform films of silicon nitride can be deposited onto a single substrate in a low pressure chemical vapor deposition process at a practicable rate from a gas mixture including a silane precursor gas and ammonia by maintaining the pressure at between about 5 and about 100 Torr. Deposition rates of up to about 185 angstroms per minute are readily achieved.
