Provided is a film forming apparatus and a film forming method that are capable of enhancing film property uniformity and improving productivity. A film forming apparatus (1) according to the present invention includes substrate temperature adjustment means (heat source 10) for adjusting substrate temperature, and film formation is performed such that sputtered particles are incident on a substrate W on a rotary substrate support table (3) from an oblique direction. By thus retaining the substrate temperature constant in film formation, it is possible to reduce temperature unevenness on the substrate in film formation and to uniformize in-plane film property. Accordingly, the film property, including film thickness, crystallinity, and component composition ratio of a film formation layer can be made uniform, and it becomes possible to manufacture, with high productivity, a resistance change device having stable device characteristics with variations in device characteristics, including in-plane resistance and magnetoresistance effect, suppressed, for example.

When setting of marking on recording data is performed, the marking is automatically performed at a suitable position corresponding to a status during image capturing. While recording of captured images is being performed, a status of a zoom operation, a moving pattern of a camera, and a feature value of video/audio signals are monitored, and a time point at which a predetermined change has occurred regarding this monitored state is detected. A predetermined data position based on this detected time point is then set as a marking position. Setting information of the marking position is stored in a structure of management information, and is stored in a storage section together with the recording data.

Before each content file is recorded first to a recording medium, a flag indicating a recording state of a content file is generated corresponding to a physical area where an index file can be continuously recorded. An index file is generated which associates attribute information with the generated flag added thereto with real data of each content file, and the generated index file is recorded to the recording medium. Since fragmentation of the physical area where the index file is recorded is restrained to a minimum level, a high-speed reading operation is realized.

A film formation apparatus and film formation method that improve film thickness uniformity. A rotation mechanism holds a target having a sputtered surface in a state inclined relative to a surface of a substrate. The rotation mechanism rotatably supports the target about an axis extending along a normal of the sputtered surface. The target supported by the rotation mechanism is sputtered to form a thin film on the surface of the substrate. When forming the thin film, the rotation mechanism maintains the rotational angle of the target.

To provide a technique which cleans an attracting face of a mechanism for electrostatically attracting an object to be processed inside a vacuum processing apparatus and keeps its attracting force constant. The method of the present invention is for cleaning an attracting face of a hot plate which holds the object to be processed inside a vacuum processing chamber through electrostatic attraction. The invention method includes a step of cleaning the attracting face of the hot plate by applying a high-frequency electric power of 13.56 MHz to a metallic base arranged under and near the hot plate in a state in which a cleaning gas is introduced into the vacuum processing chamber.

There is provided an inexpensive sputtering apparatus in which self-sputtering can be stably performed by accelerating the ionization of the atoms scattered from a target. The sputtering apparatus has: a target which is disposed inside a vacuum chamber so as to lie opposite to the substrate W to be processed; a magnet assembly which forms a magnetic field in front of the sputtering surface of the target; and a DC power supply which charges the target with a negative DC potential. A first coil is disposed in a central portion of a rear surface of the sputtering surface of the target. The first coil is electrically connected between the first power supply and the output to the target. When a negative potential is charged to the target by the sputtering power supply, the electric power is charged to the first coil, whereby a magnetic field is generated in front of the sputtering surface.
