Abstract:
A Cu film deposition equipment for a semiconductor device comprising:a load lock carrying out intermediate steps before and after a plurality of wafer processes; an aligner carrying out an alignment process, said alignment process ensuring a wafer reaches a desired position; a de-gas chamber removing residue produced on a surface of the wafer for said wafer processes; a feeding chamber provided with a robot, said feeding chamber positioning the wafer in and out of chamber for said wafer processes; a pre-cleaning chamber cleaning an inside and an outside of a pattern using plasma on the wafer fed by the feeding chamber; a barrier metal deposition chamber depositing a barrier metal on the pre-cleaned wafer; an adhesion glue layer (AGL) flash Cu deposition chamber depositing flash Cu on the barrier metal to enhance adhesion of the Cu thin film before depositing the film; a CECVD deposition chamber equally processing CE (Chemical Enhancer) and depositing a CVD Cu thin film on the wafer where flash Cu is deposited; and a plasma treatment chamber carrying out a plasma treatment on the wafer to form an equal super-filling after CE and another plasma treatment to remove iodine (I) produced on the surface of Cu thin film after the deposition of the CVD Cu thin film.
