As it has been described above, according to the processing unit (plant) 1 of embodiment, have the central authorities beyond position detecting mechanism 124 The wafer W of the periphery of workbench 124a carries out guide portion 124c supported, and the wafer W of convexly warpage is rectified Just becoming level.Thus, owing to when by central authorities' workbench 124a attracting holding wafer W, wafer W is level, Therefore the holdings face 124e of central authorities workbench 124a carries out face with the back side WR of wafer W and contacts, therefore, it is possible to lead to The holding face 124e of mistake reliably attracting holding wafer W.
And, although the position of the outer peripheral edge WE of the wafer W of warpage when top view with actual wafer W The position of outer peripheral edge WE different, but in the present invention, owing to by the wafer W level of correcting into, therefore overlooking During observation, it is identical with the position of the outer peripheral edge WE of actual wafer W, it is possible to detect the center of wafer W exactly Position.Further, it is level owing to wafer W is corrected, also therefore is able to reliably detect the position of recess N.
[shape example]
Guide portion 124c have employed the shape of word "U", but as long as can be to beyond central authorities workbench 124a The wafer W of periphery carries out the shape supported, it is possible to be any shape.Such as, guide portion 124c can also be Word " U " or the shape of " C ", it is also possible in the way of utilizing multiple dot point wafer W, arrange multiple guide portion.
Further, position-detection sensor 124d uses the example of optical pickocff be illustrated, but the most also may be used To be shot the outer peripheral edge WE of wafer W by filming apparatus.In this case, crystalline substance is inferred according to shooting image The bias of sheet W.
And, although first infer that the center of wafer W detects the position of recess N again but it also may in inspection The center of wafer W is inferred after surveying the position of recess N.Thereby, it is possible to avoid being detected as by recess N by mistake Outer peripheral edge WE.
