Abstract:
1. A method for static elimination of a cleaning target in a cleaning step, the method comprising the steps of: disposing in a cleaning apparatus a conducting means capable of coming into contact with and separating from the cleaning target at a plurality of portions thereof, the conducting means comprising a plurality of conducting members each having a shape of a pin and a substrate which holds the conducting members in such a way that they are capable of advancing and retreating in a direction substantially perpendicular to the cleaning target; moving the conducting members substantially perpendicular to the cleaning target such that the conducting members come into contact with the plurality of portions of the cleaning target; maintaining contact between the conducting members and the plurality of portions of the cleaning target; and eliminating, by grounding via the conducting means, the static electrification on the cleaning target that is caused by a cleaning member during cleaning.
