摘要:A manufacturing method and manufacturing device for high-precision thin filmdevices is disclosed, whereby the film thickness and film thickness distribution of a
transparent film is measured to a high degree of accuracy during a CMP process withoutbeing affected by the film thickness distribution between LSI regions or within thesemiconductor wafer surface generated by CMP processing. Film thickness is measuredby specifying relatively level measurement regions, according to a characteristic quantityof the spectral waveform of the reflected light from the transparent film, such as thereflection intensity, frequency spectrum intensity, or the like, thereby permitting highlyaccurate control of film thickness. The leveling process in CMP processing can be
optimized on the basis of the film thickness distribution. The film deposition conditions inthe film deposition stage and the etching conditions in the etching stage can also beoptimized. Accordingly, a high-precision semiconductor device can be manufactured.
