Abstract:
An inline processing system for patterning magnetic recording layers on hard discs for use in a hard disc drive. Discs are processed on both sides simultaneously in a vertical orientation, in round plate-like holders called MDCs. A plurality (as many as 10) discs are held in a dial carrier of the MDC, and transferred from one process station to another. The dial carrier of the MDC may be rotated and/or angled at up to 70° from normal in each process station, so that one or a plurality of process sources may treat the discs simultaneously. This configuration provides time savings and a reduction in the number and size of process sources needed. A mask enhancement process for patterning of magnetic media, and a filling and planarizing process used therewith, are also disclosed.
Abstract:
A rotating disk reactor for chemical vapor deposition includes a vacuum chamber and a ferrofluid feedthrough comprising an upper and a lower ferrofluid seal that passes a motor shaft into the vacuum chamber. A motor is coupled to the motor shaft and is positioned in an atmospheric region between the upper and the lower ferrofluid seal. A turntable is positioned in the vacuum chamber and is coupled to the motor shaft so that the motor rotates the turntable at a desired rotation rate. A dielectric support is coupled to the turntable so that the turntable rotates the dielectric support when driven by the shaft. A substrate carrier is positioned on the dielectric support in the vacuum chamber for chemical vapor deposition processing. A heater is positioned proximate to the substrate carrier that controls the temperature of the substrate carrier to a desired temperature for chemical vapor deposition.
Abstract:
A linear cluster deposition system includes a plurality of reaction chambers positioned in a linear horizontal arrangement. First and second reactant gas manifolds are coupled to respective process gas input port of each of the reaction chambers. An exhaust gas manifold having a plurality of exhaust gas inputs is coupled to the exhaust gas output port of each of the plurality of reaction chambers. A substrate transport vehicle transports at least one of a substrate and a substrate carrier that supports at least one substrate into and out of substrate transfer ports of each of the reaction chambers. At least one of a flow rate of process gas into the process gas input port of each of the reaction chambers and a pressure in each of the reaction chambers being chosen so that process conditions are substantially the same in at least two of the reaction chambers.
Abstract:
Method and apparatus for processing a substrate (44) with an energetic particle beam (42). Features (66) on the substrate (44) are oriented relative to the energetic particle beam (42) and the substrate (44) is scanned through the energetic particle beam (42). The substrate (44) is periodically indexed about its azimuthal axis (45) of symmetry, while shielded from exposure to the energetic particle beam (42), to reorient the features (66) relative to the major dimension (49) of the beam (42).
