Semiconductor device manufacturing method and semiconductor device manufacturing apparatus
Abstract:
A predicted film formation rate value is computed based on a film formation rate prediction formula obtained in advance and apparatus parameters obtained during a previously-performed film formation process. A processing time required for an amount of film formed on a wafer to reach a predetermined target film thickness is computed based on the computed predicted film formation rate value and the target film thickness. Then, according to the computed processing time, a film-formation process is performed on wafers. In addition, it is determined whether the computed predicted film formation rate value is within a predetermined range, and only when it is determined to be within the predetermined range, the film formation process may be performed.
