Abstract: Wafers are prevented from getting damaged on delivery thereof from a sucking and carrying device to a table. A wafer before planarization sucked and held by a sucking board is positioned above a table. Next, wafer is vacuum-attracted by the table, and the table is moved upward by that attraction power in a direction to suck the wafer so as to vacuum-suck it on the table. Subsequently, the wafer is sucked and held only by the table by releasing the sucking and holding thereof by the sucking board.

The device includes a dielectric barrier discharge lamp and a feed device for applying a high voltage to this dielectric barrier discharge lamp, wherein the feed device via a set-up transformer applies a high voltage with an essentially periodic waveform to the barrier discharge lamp. Moreover, the applied high voltage first produces a steep rising waveform and then ringing, wherein the ratio of the difference between a second extreme value point and a third extreme value point to the difference between a first extreme value point and the second extreme value point of the ringing is less than or equal to 30%. It is a further object of an embodiment of the present invention to reduce or eliminate the ringing.
