Patent ID: 6872285

Claim:
A system for depositing a magnetic film or depositing an underlying film, comprising: a chamber in which the film is deposited onto a substrate by sputtering; a target that is provided in the chamber and made of material of the film to be deposited; a sputter power source that applies voltage to the target for the sputtering; a direction control member that controls sputter-particles released from the target during the sputtering; and a rotation mechanism that rotates the direction control member relatively against the substrate, wherein the direction control member is provided between the substrate and the target; the direction control member provides a passage for the sputter-particles; the direction control member lets the sputter-particles selectively pass through, thereby allowing magnetic anisotropy to the magnetic film; the target is provided coaxially to the substrate; the target is ring-shaped and has a center opening coaxial to the substrate; the direction control member is formed with a plurality of louver boards lengthened radially; and width direction of each louver board is perpendicular to the substrate.
