Job Description

Drive reliability robustness for WB-related failure mechanisms (e.g., NSOP/NSOL, wire sweep, heel crack, IMC-related degradation, corrosion/Al pad damage, Cu oxidation, cratering, stitch/bond lift, EFO variability as applicable).

Your role

Key responsibilities in your new role

• Lead investigations into critical excursions and systematic issues using structured methods (8D, DMAIC, DoE, FMEA, Fault Tree Analysis), delivering clear root cause and permanent corrective actions.
• Drive reliability robustness for WB-related failure mechanisms (e.g., NSOP/NSOL, wire sweep, heel crack, IMC-related degradation, corrosion/Al pad damage, Cu oxidation, cratering, stitch/bond lift, EFO variability as applicable).
• Support qualification and monitoring: pull/shear, ball/stitch geometry, intermetallic growth, microsectioning, SAM/X-ray, and environmental stress results interpretation.
• Define key parameters and interactions (US power/force/time, scrub, bonding temperature, EFO, N₂ forming gas, clamp settings, loop profile, ultrasonic transducer health).
• Mentor senior engineers and act as a technical reviewer for WB-related changes, deviations, and risk assessments. Partner with package design, device design, wafer fab (pad stack), materials, equipment engineering, test, and quality to ensure end-to-end manufacturability and reliability.
• Interface with suppliers (wire, capillaries, bonders, consumables) and drive joint development, supplier qualification, and change management. Drive digitalization and automation projects with the vision of autonomous factories.

Your profile

Qualifications and skills to help you succeed

• 8–15+ years in semiconductor assembly/packaging with deep expertise in wire bonding (Al/Cu/Au)
• Proven HVM ownership strongly preferred.
• Strong understanding of bonding physics, metallurgy/intermetallics, pad stack interactions, contamination control, corrosion mechanisms, and thermal-mechanical effects.
• Solid experience with process characterization and statistics: SPC, Cp/Cpk, MSA, GR&R, DoE, capability studies.
• Hands-on familiarity with metrology/failure analysis methods relevant to WB (pull/shear, microsections, SEM/EDS as available, X-ray/SAM).
• Demonstrated ability to lead cross-site/cross-functional teams without direct reporting lines; confident in technical decision-making and escalation handling.
