What confuses us is that replacing the silane gas source and the filter on the pipeline can only temporarily improve the abnormal polycrystalline particles, and problems will occur in the sixth process.
To our bewilderment, replacing the silane gas source and the filter on the pipeline can only briefly improve the polysilicon particle anomaly, and the process will have problems by the sixth time.
