Title: Vacuum processing method
Inventor: MAEHIRA KEN
IPC: H01L21/68
Filed: 2000-04-06
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum processing method which can remove or reduce residual charges, while maintaining a attraction to a certain extent, at vacuum processing of an electrostatically attracted substrate. SOLUTION: In this vacuum processing method, reversing time as to minimize the residual charges at the termination of electrostatic attraction is obtained previously, so that during the formation of a film, the polarity of magnetism of a voltage applied to chuck electrodes 5 and 6 is reversed once at the previously obtained reversing time. Thus although the amount of charges between the substrate 30 and the electrostatic chuck plate 4 is large immediately prior to the reversing on time, but it becomes small at termination of electrostatic attraction, whereby reduction in the attraction during electrostatic attraction can be avoided and residual charges after completion of the electrostatic attraction can be reduced. Accordingly, after the removal of electrostatic attraction, the electrostatic attraction due to the residual charges causing the substrate 30 to slip off from lift pins 9 and 10 or to be displaced on the pin 9 and 10 is prevented.
