Title: Vacuum treatment method
Inventor: FUWA KO
IPC: B65G49/06
Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a technique for detaching a substrate easily from an electrostatic absorber for a short time after finishing carrying it in the case of carrying the substrate in the state of absorbing and holding it by the electrostatic absorber. SOLUTION: After the first voltage V1 is applied to an electrode within the electrostatic absorber to absorb the substrate by the electrostatic absorber, the voltage to be applied to the electrode is changed to the second voltage V2 during moving to lower an absorbing power. Thus, when moving of the substrate is finished, compared with a conventional method which applies the same voltage to the electrode, the quantity of residual electric charges between the substrate and the electrostatic absorber is reduced and residual absorptive power is lowered. Thus, a time required until the substrate becomes detachable from the electrostatic absorber can be reduced compared with conventional embodiments.  In particular, in the case of extinguishing the residual electric charge by applying voltage of a reverse polarity to the electrode for a short period after finishing moving, it is possible to extinguish the residual electric charge without applying with high voltage as in the conventional method.
