Abstract
A lamination method includes measuring a flatness of a first stage on which an object to be processed is placed, measuring an amount of sagging of an attachment roller which presses a film to attach the film to the object to be processed, primarily adjusting the flatness of the first stage based on the amount of sagging of the attachment roller, and secondarily adjusting the flatness of the first stage in a way such that a flatness of an end of the first stage relative to a center of the first stage has a smaller step than the first stage adjusted primarily.
Claims19
A lamination method comprising:
- measuring a flatness of a first stage on which an object to be processed is placed;
- measuring an amount of sagging of an attachment roller which presses a film to attach the film to the object to be processed;
- primarily adjusting the flatness of the first stage based on the amount of sagging of the attachment roller;
- and
- secondarily adjusting the flatness of the first stage in a way such that a flatness of an end of the first stage relative to a center of the first stage has a smaller step than the first stage adjusted primarily.

A lamination device comprising:
- a first stage on which an object to be processed is placed;
- a first sensor which measures a flatness of the first stage;
- an attachment roller which presses a film to attach the film to the object to be processed;
- a second stage on which the film is placed, wherein the second stage is movable in a tilted position;
