Semiconductor Advanced Packaging

Semiconductor Advanced Packaging

Overview

In the post‑Moore era, advanced semiconductor packaging has become a core driving force for chip performance improvement. Technologies such as 2.5D/3D IC, SiP, Flip‑Chip and TCB thermal‑compression bonding are being rapidly industrialized across domestic manufacturing lines, while local material substitution is gathering momentum. This field imposes stringent performance benchmarks for micro‑interconnection, low void formation, minimal thermal stress and long‑term operational reliability.

Core Application Scenarios

• AI high‑performance computing chips

• Wide‑bandgap power devices including IGBT, SiC and GaN

• Flip‑Chip & TCB thermal compression bonding processes

• Chip die‑attach and shielding frame assembly

Key Technical Challenges

• Reliable formation of ultra‑fine micro‑solder joints under miniaturized pitch

• Strict control of void ratio and interfacial thermal stress to prevent chip damage

• Satisfy multi‑dimensional reliability validation including temperature cycling and power cycling

• Maintain ultra‑low ionic residue to mitigate electrochemical migration risks
