た問題がある。However, in the case where a large number of suction holes are opened on the plate surface by electric discharge machining or micro drilling or the like for suction, the surface accuracy is deteriorated due to the machining, and the work is not filmed. In the case of a thin flexible film such as a film used for a liquid crystal or the like, there is a problem that a hole of the hole is left on the film when the film is sucked because the processing hole diameter becomes large. In addition, since the work is sucked only at the hole portion, large holes formed by machining cannot achieve uniform suction because the hole density on the plate surface becomes coarse, and as a result, heating at a uniform temperature over the entire surface of the work cannot be performed. .

プレートを提供することを課題とした。Accordingly, the present invention is to provide a suction hot plate which has good surface accuracy and does not leave traces of holes due to suction even on a thin and flexible work, and is capable of maintaining the entire surface of the work at a uniform temperature. Assigned.

ワークの表面温度を均一にすることができる。The suction hot plate of the present invention has a good surface accuracy because the suction holes are not formed by machining but are porous fine holes. Even if the work is a thin and flexible one such as a film, the holes are formed by suction. Leave no trace of In addition, the suction by suction does not concentrate on large holes with coarse density like processing holes, but it becomes a state like surface suction over the entire suction plate surface due to fine holes densely present on the entire surface, resulting in the surface of the workpiece The temperature can be made uniform.
