Sr. Staff Packaging Engineer- Process Package Integrity & Bumping

Company:

Job Area:

General Summary:

The engineer will be a key member of the Process Package Integration and bumping process team, driving technology development and new product introduction (NPI) with primary ownership of wafer bumping (Far-BEOL) process integration, qualification, and high-volume readiness across multiple silicon technology nodes, foundries, bumping lines, and assembly houses (OSATs). Key responsibilities include defining bumping process flows (passivation/UBM/RDL/bump), establishing process windows and controls, leading DOE-based optimization, and partnering with suppliers to improve yield, reliability, and cost. The role works closely with foundry FBEOL teams, bumping/assembly partners, and internal package design, process, quality, test, and product development teams to deliver robust bumping solutions enabling advanced packaging (flip-chip, RDL/fan-out, and 2.5D/3DIC). The candidate will also lead bumping house/line bring-up, qualification, and ongoing performance management to expand capacity and ensure multi-source readiness.

Skill/Knowledge:

• Expertise in Far-BEOL bumping process modules and integration, including passivation openings, UBM, RDL (as applicable), solder/Cu pillar bump formation, and associated materials/equipment.
• Deep knowledge of flip-chip bump design intent and assembly interactions (bump metallurgy, pitch scaling, coplanarity, warpage interactions), and wafer-level packaging (RDL) / fan-out process considerations impacting bumping.
• Strong technical skills in bumping process/material/equipment characterization (metrology and inline controls), failure analysis, DOE design, statistical data analysis, and FMEA to drive yield and reliability improvements.
• Experience leading bumping process qualification and production release activities (process window definition, control plans/SPC, GR&R, and risk mitigation) for NPI and high-volume manufacturing.
• Proven track record enabling package development through robust bumping solutions for flip-chip, RDL/fan-out RDL, and advanced packaging technologies (2.5D/3DIC).
• Expertise in manufacturing execution for Far-BEOL bump structures and bump line operations, including new bumping line bring-up, tooling/equipment qualification, and production ramp (HVM readiness).
• Hands-on experience in project leadership and supplier management for external bumping houses/OSATs, including KPI definition, yield excursions containment, and continuous improvement programs.
• Experienced interfacing with foundries and bumping houses on process integration, change control, line qualification, and multi-source/capacity expansion.
• Understanding of heterogeneous integration (2.5D/3DIC) packaging flows and how bumping/interconnect schemes (micro-bumps, fine-pitch RDL) impact downstream assembly and reliability.
• Ability to design and drive novel test vehicles/structures for bump/RDL process characterization and process-package interaction (reliability, electromigration, mechanical integrity).
• Experience with chip and substrate design tools such as Calibre, Virtuoso, CAD, SiP, and GDS.
• Understanding of chip-top physical design flow and communication with package design teams.
• Minimum of 8-10 years hands-on experience in silicon interconnect process, bumping and/or RDL process, new technology qualification and production.

Additional Skills

• Good analytical and project management skills.
• Excellent capability of innovation and creativity.
• Highly motivated and committed to success of the individual and the team.
• Superior interpersonal communication skills. Publish technical reports.
• Able to work flexible hours. Occasional domestic/international travels needed.

Minimum Qualifications:

OR

Master's degree in Chemical Engineering, Electrical Engineering, Mechanical Engineering, or related field and 5+ years of System/Package Design/Technology Engineering or related work experience.

OR

PhD in Chemical Engineering, Electrical Engineering, Mechanical Engineering, or related field and 4+ year of System/Package Design/Technology Engineering or related work experience.
