发明名称 Apparatus for integrated monitoring of wafers and for process control in semiconductor manufacturing and a method for use thereof
摘要 The present invention relates to an integrated apparatus for monitoring wafers and for process control in the semiconductor manufacturing process, by means of at least two different measurements that can be installed inside any part of the semiconductor production line, i.e., inside the photocluster equipment, the CVD equipment or the CMP equipment. The apparatus comprises a measuring unit for performing at least one optical measurement in predetermined sites on said wafer, illumination sources for illuminating said wafer via measuring unit, supporting means for holding, rotating and translating the wafer and a control unit. The measuring unit comprises: at least two measuring sub-units, one of them being normal-incidence optical measuring system.
