摘要:
The invention relates generally to processes for producing electrically conductive noble metal thin films on a substrate by atomic layer deposition. According to one embodiment of the invention a substrate with a surface is provided in a reaction chamber and a vaporised precursor of a noble metal is pulsed into the reaction chamber. By contacting the vaporised precursor with the surface of the substrate, no more than about a molecular layer of the metal precursor is formed on the substrate. In a next step, a pulse of molecular oxygen-containing gas is provided in the reaction chamber, where the oxygen reacts with the precursor on the substrate. Thus, high-quality metal thin films can be deposited by utilising reactions between the metal precursor and oxygen. In one embodiment, electrically conductive layers are deposited in structures that have high aspect ratio vias and trenches, local high elevation areas or other similar surface structures that make the surface rough.

PROBLEM TO BE SOLVED: To provide an in-line film forming apparatus capable of suppressing generation of vibrations accompanying an open/close operation of a gate valve and opening and closing the gate valve at a high speed. SOLUTION: Just before a piston 114 in a cylinder 115 reaches an end in one direction, a second valve 117a is fully closed to discharge air through only a second flow rate control valve 117b; and just before the piston 114 in the cylinder 115 reaches an end in the other direction, a first valve 116a is fully closed to discharge air through only a first flow rate control valve 116b. Thereby, shocks due to the contact between the end of the cylinder 115 and the piston 114 are reduced, and generation of vibrations can be suppressed. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a perpendicular medium in which an isolation structure of an underlayer is formed using a simple method as in a conventional manufacturing process for a medium of continuous films, the method suppressing dispersion of alignment and reducing magnetic cluster size in a magnetic recording layer, while achieving high recording density by reducing the thickness of the underlayer. SOLUTION: The perpendicular magnetic recording medium includes at least an underlayer and a magnetic recording layer sequentially laminated on a nonmagnetic substrate. The underlayer consists of crystal grains and an amorphous grain boundary, and the crystal grain has a shape holding a relation (an area of a bottom region at an initial stage of growth)>(an area of a top region).

PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic recording medium, which is difficult to accomplish with a single vacuum film-formation device having an insufficient number of chambers, by connecting vacuum film-formation devices. SOLUTION: In the method for manufacturing the disk-shaped magnetic recording medium, a film-formation device is used which is formed by connecting a plurality of vacuum film-formation devices 101, 201 by a connecting device 301 provided with a disk transport system 302.
