摘要： According to the invention, when targets are sputtered, each of them moves with respect to a substrate; and therefore, the entire area of the substrate is opposed to the targets during sputtering, so that a film of homogeneous quality can be formed on the surface of the substrate. During the sputtering, not only the targets but also magnetic field forming devices are moved relative to the targets, and therefore, a large area of the targets can be sputtered. In addition, when the magnetic field forming devices are also moved with respect to the substrate, the region of the target which is highly sputtered, moves with respect to the substrate, so that the thickness distribution of the film formed on the substrate can be even more uniform.

摘要： [Object] To provide a sputtering apparatus, a thin-film forming method, and a manufacturing method for a field effect transistor, which are capable of reducing damage of a base layer.[Solving Means] The sputtering apparatus 100 includes a conveying mechanism, a first target Tc1, a second target (Tc2 to Tc5), and a sputtering means. The conveying mechanism conveys a supporting portion, which is arranged in an inside of a vacuum chamber and supports a substrate, linearly along a conveying surface parallel to the surface to be processed of the substrate. The first target Tc1 is opposed to the conveying surface with a first space therebetween. The second target (Tc2 to Tc5) is arranged on a downstream side in a conveying direction of the substrate with respect to the first target Tc1, and is opposed to the conveying surface with a second space smaller than the first space therebetween. The sputtering means sputters each target. According to this sputtering apparatus 100, the damage received by the base layer is small, and hence it is possible to form a thin-film having good film-forming properties.

摘要： A plurality of targets are disposed in parallel with, and at a given distance to, one another. In case a predetermined thin film is formed by sputtering, the occurrence of non-uniformity in the film thickness distribution and the film quality distribution can be restricted. During the time when electric power is charged to a plurality of targets (31a to 31h) which are disposed inside a sputtering chamber (11a) so as to lie opposite to the process substrate (S), and are disposed at a predetermined distance from, and in parallel with, one another, thereby forming a predetermined thin film by sputtering, each of the targets is reciprocated at a constant speed in parallel with the process substrate. Also, magnet assemblies that form tunnel-shaped magnetic flux (M) in front of each target are reciprocated at a constant speed in parallel with each of the targets. When each of the targets has reached a turning position of the reciprocating movement, the reciprocating movement of each of the targets is stopped for a predetermined period of time.

摘要： In a magnetron sputtering apparatus an arrangement is made such that the peripheral portion of a target is uniformly eroded to attain a high efficiency in target utilization and, in addition, that an abnormal discharging hardly occurs to thereby enable satisfactory thin film forming. A magnet assembly is provided behind a target that is disposed opposite to the process substrate. This magnet assembly has a central magnet that is disposed linearly along the longitudinal direction, and a peripheral magnet that is disposed so as to enclose the periphery of the central magnet, while changing the polarity on the side of the target. At this time, among the respective magnetic fluxes generated between the central magnet and the peripheral magnet at the longitudinally end portions of the magnet assembly, the position at which the vertical component of the magnetic field becomes zero is locally shifted to the central magnet within a certain range.
