  • Patent number: 8011315
    Abstract: A thin film forming apparatus such that a substrate can be easily fixed/removed to/from the outer circumferential surface of a drum type substrate holder through a simple arrangement. The drum type substrate holder (5) is supported in a horizontal posture rotatably about a horizontal rotational shaft in a film deposition chamber A jig (13) holding a substrate (12) fixedly is transferred by an arm horizontally onto the outer circumferential surface of the drum type substrate holder (5), and an end part (13b) of the substrate fixing jig (13) can be secured by a securing device (14) provided at the corner part (5a) of the outer circumferential surface of the drum type substrate holder (5).

  • Patent number: 7927472
    Abstract: To provide a method of controlling film thickness of dielectric multilayer film, such as optical thin film, with high precision, an optical film thickness controlling apparatus and a dielectric multilayer film manufacturing apparatus that can control the film thickness based on the same method, and dielectric multilayer film manufactured using the controlling apparatus or manufacturing apparatus. An optical film thickness controlling apparatus includes a film formation device 15 having a rotatable substrate 23 and a sputtering target 28, a photodiode 16 that detects each of a plurality of monochromatic light beams applied to the rotatable substrate along a radius thereof at predetermined intervals, and an A/D converter 17, in which a movable shutter 29 that moves along the direction of the radius of the rotatable substrate 23 to shut off film formation on the substrate 23 is provided between the substrate 23 and the target 28.

    Abstract: A method of controlling film thickness of dielectric multilayer film with high precision, an optical film thickness controlling apparatus and a dielectric multilayer film manufacturing apparatus that can control the film thickness. An optical film thickness controlling apparatus includes a film formation device having a rotatable substrate and a sputtering target, a photodiode that detects each of a plurality of monochromatic light beams applied to the rotatable substrate along a radius thereof at predetermined intervals, in which a movable shutter that moves along the direction of the radius of the rotatable substrate to shut off film formation on the substrate between the substrate and the target. From each of the monochromatic light beams, a quadratic regression function of reciprocal transmittance is calculated by a least squares method, and a CPU and a motor driver move the movable shutter to shut off the film formation at the film formation region.
