Cu Trace Formation Technology by SAP using Dry Process


Compared to the conventional Cu trace structure by electroless Cu plating on the rough resin surface, a high-quality Cu trace structure by dry process has been achieved on smooth surface without undercut.


  • Fine Cu traces using semi-additive process (SAP).
  • Advanced dry processes such as plasma etching and sputtering used in conventional semiconductor technologies.
