Title: Method of detecting a charge source of residual charges on a wafer
Inventor: YIM SANG MAN
IPC: H01L21/66
Filed: 2020-12-28
Abstract: Disclosed is a method for detecting a charge source of residual charges of a substrate of a plasma processing device. The method generates a part replacement time table in which each component part of a substrate processing device is aligned by replacement dates, and detects the residual charge density of a substrate unloaded from a process chamber after a processing process is completed to generate a residual charge time table in which the residual charge density is aligned by detection dates. The method calculates the average charge density prior to the replacement of a part of interest from the most recent part replacement day before the replacement day of the part of interest to acquire non-replacement charge density, and calculates the average charge density up to the detection day of the charge density after the replacement of the part of interest to acquire replacement charge density. If the difference between the replacement charge density and the non-replacement charge density exceeds an allowed range, the part of interest is detected with a charging source of residual charges. Component parts affecting residual charges of substrates can be simply detected to be discharged or replaced.
