Patent ID: 7789653

Claim:
An imprinting apparatus comprising: a mount to support a subject body; a support to support a template configured to imprint a pattern on the subject body, the support defining an axis and being controllably movable toward the mount along the axis and swingable around the axis; three or more regulation sets attached to the support and arranged around the axis at intervals, each of the regulation set including an actuator in contact with the support so as to swing the support to position the support in a desired angular orientation relative to the subject body and maintain the angular orientation, and a distance measurement device configured to measure a distance to the subject body, the actuators and the distance measurement devices of the three or more regulation sets being respectively arranged correspondently to each other; and a controller configured to calculate regulation voltages to drive the actuators from values respectively measured by the distance measurement devices so that the orientation is three-dimensionally regulated to keep parallelism between the imprinting face of the template and a surface of the subject body.
