A substrate processing device in which a film is formed on a substrate while a magnetic field, by a magnet arranged in the periphery of a substrate holder, is imparted on to the surface of a substrate mounted on the substrate holder while the substrate holder is rotated, wherein a rotation mechanism for the magnet and a rotation mechanism for the substrate holder are independently provided and controlled and, furthermore, in that it is provided with a device for detection of the magnetic field orientation, a device for detection of the prescribed orientation of the substrate, and a mechanism which, using the output of said two detection devices, affords rotation in which the prescribed direction of the substrate and the direction of the magnetic field are aligned within a prescribed angle.
