Abstract:
A semiconductor manufacturing apparatus, which performs predetermined processing for a group of wafers supplied by a pre-processor that performs preliminary processing, comprising:a data storage unit for storing wafer processing history data received from said pre-processor; a target value storage unit for storing a processing target value for said semiconductor manufacturing apparatus; an identification unit for identifying a wafer supplied by said pre-processor based on identification information located on said wafer; a processor for employing said wafer processing history data and said processing target value to determine processing conditions for said wafer identified by said identification unit; a conveying unit for transporting said wafer from said identification unit to a wafer processor; a controller for controlling said wafer processor in accordance with said wafer processing conditions instructed by said processor; and a determination unit for examining the condition of said wafer that has been processed by said wafer processor to determine whether said wafer is good or bad, wherein, in accordance with the results obtained by said determination unit, said processor unit determines whether the processing of said wafer is to again be performed by said wafer processor, and as necessary, again sets said processing conditions.
