Senior Packaging Engineer (Advanced Semiconductor Packaging)

Summary

Designs and develops advanced semiconductor packaging solutions like Flip-Chip and 2.5D/3D, optimizing electrical, thermal, and mechanical performance from concept to mass production.

Key Responsibilities

· Package Architecture & Design: Define and develop semiconductor package solutions (e.g., Flip-Chip, Wirebond, 2.5D/3D, Chiplets, CoWoS, FOWLP, SiP) from concept to mass production.

· Evaluate package architectures, interconnect strategies, substrate stack-ups, and material selections to meet electrical, thermal, mechanical, and reliability requirements.

· Design and define substrate stack-ups, routing strategies, and interconnect structures to meet high-speed, high-density, and manufacturability requirements.

· Collaborate with SI/PI teams to optimize package-level electrical performance including high-speed IO and power delivery.

· Simulation & Multi-Physics Collaboration: Collaborate with thermal and mechanical engineering teams to perform simulations (warpage, stress, CTE mismatch).

· New Product Introduction (NPI) &Manufacturing: Lead package development through NPI to high-volume manufacturing (HVM), ensuring DFM, cost, yield, and reliability targets.

· Collaborate with OSAT vendors and substrate suppliers to ensure process readiness, qualification, and ramp.

· Process Development & Yield Improvement: Develop backend processes (bumping, assembly, molding, underfill).

· Materials & Reliability Engineering: Evaluate packaging materials and define BOM.

· Ensure reliability through qualification and failure analysis.

· Cross-functional Collaboration: Work with IC design, SI/PI, system, and manufacturing teams for chip-package-system co-design.

Requirements:
· Master’s degree or above in Mechanical Engineering, Electrical Engineering, Materials Science, Microelectronics, or related fields.

· 3+ years of experience in semiconductor packaging, preferably in advanced packaging.

· Strong understanding of packaging technologies such as Flip-Chip, FOWLP, WLCSP, and 2.5D/3D integration.

· Hands-on experience in substrate design (stack-up definition, routing, and manufacturability).

· Experience with NPI, OSAT engagement, and high-volume manufacturing.

· Knowledge of package materials, assembly processes, and reliability standards.
