There is provided a robot hand for substrate transfer in which the robot hand is so arranged that, even in case a substrate (S) gives rise to warping, the substrate (S) can be stably supported. On an upper surface of the robot hand there is formed a first seating surface on which is seated a lower-surface peripheral portion of the substrate (S) and, on a periphery thereof, there is formed an upwardly extended step. The step is provided with a plurality of stair-shaped stages. On an upper surface of the robot hand inwardly away from the first seating surface there is provided a second seating surface which is inclined downward toward the center of the substrate (S) such that a lower surface of the substrate (S) is seated on the second seating surface when the substrate (S) is warped downward into a concave shape.

A vibration isolator includes layered rubbers interposed between a support body and a movable body, and a pair of dampers attached to the support body at one ends and to the movable body at the other ends. The layered rubbers are arranged to be spaced apart in an anterior and posterior direction and in a left and right direction, with reference to a direction in which an operator faces when seated. One of the dampers is arranged at a position corresponding to a middle of the left and right direction between the layered rubbers arranged in the left and right direction, and aligned in the anterior and posterior direction. The other one of the dampers is arranged closer to an anterior side than a middle of the anterior and posterior direction between the layered rubbers arranged in the anterior and posterior direction, and aligned in the lift and right direction.

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.

One element is taken from a machined shape. When the element is a straight line element, whether or not the distance D between the start point and the end point of the element in a direction orthogonal to the axis of rotation of the workpiece is equal to or greater than a preset value Ds is determined. In addition, whether or not an angle A that the straight line element makes with the Z-axis is equal to or greater than a preset angle Aa is determined. When the distance D is equal to or greater than the preset value Ds and the angle A is equal to or greater than the preset angle Aa, a program is created with the cutting direction reversed from the profile direction.
