Summary:PROBLEM TO BE SOLVED: To stably suck and fix even a warped substrate on a table.SOLUTION: A substrate suction device 1 is provided in a table 2 including a plurality of through-holes 2a. The device 1 comprises a flange member 4, a cylinder 5 and a coil spring 6. The flange member 4 comprises a housing part 10a insides, comprises a communication hole 10b that is communicated to a suction source, on a bottom of the housing part 10a and is fixed in such a manner that the housing part 10a is communicated to the through-hole 2a of the table 2. The cylinder 5 is housed in the through-hole 2a of the table 2 and the housing part 10a of the flange member 4, and freely movable upwards and downwards and includes a suction hole 5a insides. The coil spring 6 energizes the cylinder 5 upwards. The cylinder 5 is then formed in such a manner that a projection area in a view from a lower side does not exceed an area of an upper end face.SELECTED DRAWING: Figure 1 【課題】たわみのある基板であっても、安定してテーブル上に吸着して固定することができるようにする。【解決手段】この基板吸着装置1は、複数の貫通孔2aを有するテーブル2に設けられている。この装置1は、フランジ部材4と、シリンダ5と、コイルスプリング6と、を備えている。フランジ部材4は、収容部10aを内部に有するとともに、収容部10aの底部に吸着源に連通する連通孔10bを有し、収容部10aがテーブル2の貫通孔2aに連通するように固定される。シリンダ5は、テーブル2の貫通孔2a及びフランジ部材4の収容部10aに収容され、上下動自在であり、内部に吸引孔5aを有する。コイルスプリング6は、シリンダ5を上方に付勢する。そして、シリンダ5は、下方から視た投影面積が上端面の面積を超えないように形成されている。【選択図】図1
