Abstract: |
Integrated circuit manufacturing, also called chip manufacturing, is becoming more and more important to the entire industrial chain, and surface technologies such as electrochemical deposition (electroplating) have played a very key role.This paper introduces surface technologies such as electrochemical deposition, physical vapor deposition(PVD), chemical vapor deposition(CVD), and polishing used in integrated circuit manufacturing. And many processes such as the copper interconnect electroplating, chemical mechanical polishing (CMP), through silicon via (TSV) vertical interconnect electroplating copper filling.Chip surface rewiring (RDL) copper electroplating process, bonding bump (Bump) electroplating copper/tin process, integrated circuit lead frame/package substrate electrochemical etching process, etc are also discussed.This paper aims to summarize the development of surface technologies such as electrochemical deposition, deeply analyze the new characteristics of traditional electroplating technology in integrated circuit manufacturing, and promote the progress of integrated circuit manufacturing technology. |
