Job summary

Syenta seeks an experienced electrochemist to diagnose failed copper deposits, design rapid experiments, and convert findings into robust, repeatable recipes for production. You will partner with process and equipment engineers to shape how plating systems are specified and scaled for advanced packaging interconnects.

You will drive DOE studies, develop electrolyte chemistries, and map process windows that ensure uniform deposition and high-quality RDL/microvia fills.

Qualifications

• Deep practical understanding of electrodeposition, electrochemical kinetics, mass transport and interfacial phenomena.
• Hands‑on experience developing and troubleshooting electrochemical deposition processes.
• Experience with electrolyte chemistry, electrochemical instrumentation and analytical characterisation.
• Strong experimental design, data analysis and root‑cause investigation skills.
• Demonstrated ability to independently solve complex technical problems and deliver measurable results.

Responsibilities

• Set the technical direction for, and lead the development and optimisation of, copper electrodeposition processes for fine‑pitch RDL, microvias and high‑aspect‑ratio structures.
• Investigate electrochemical kinetics, mass transport, current distribution, nucleation and deposition morphology.
• Develop electrolyte formulations, additives and operating conditions to improve uniformity, filling quality and defect performance.
• Identify and eliminate deposition defects, including voids, shorts, overplating, roughness and nonuniform growth.
• Design and execute rigorous experiments (DOE) to establish robust and reproducible process windows, and set the standard for experimental rigour across the team.
• Develop stamp pre‑plating, conditioning, recharging and cleaning processes.
• Apply electrochemical characterisation techniques, including cyclic voltammetry, chronoamperometry, impedance spectroscopy and polarisation measurements.
• Correlate electrochemical behaviour with SEM/FIB cross‑sections, surface metrology, material properties and electrical performance.
• Collaborate closely with process and equipment engineers to translate laboratory results into scalable manufacturing systems.
• Define electrochemical requirements for automated plating equipment, electrolyte delivery, multi‑zone current control and in‑line process monitoring, and influence equipment architecture decisions.
• Document experimental results, establish SOPs and drive continuous improvement in process yield, repeatability and throughput, mentoring colleagues in the process.
