YOUR ROLE

As aSeniorWets Process Development Engineer, you will be the technical anchor for our end-to-end wet process portfolio. You will be responsible for the following:

• Process Architecture:Lead the design and optimization of advanced plating processes (including NiPdAu/ENEPIG), wet etching, resist stripping, and precision cleaning modules.
• Root Cause Analysis:Tackle complex, localized process defects—such as thickness non-uniformity or interfacial passivation—using advanced analytical tools (SEM/EDX, AFM).
• Technology Scaling:Drive the transition of new wet processes from initial lab-scale concepts to robust, high-volume manufacturing (HVM) readiness.
• Chemical Innovation:Evaluate and integrate next-generation chemistries, including the management of complex stabilizer systems and additive interactions to improve process margins.
• DOE Leadership:Design and execute sophisticated multi-variate experiments to isolate variables in electrochemical reactions and surface preparation.
• Cross-Functional Integration:Collaborate with Lithography, PVD, CVD, R&D, and Assembly teams to ensure seamless process compatibility across the entire device fabrication flow.

YOUR SKILLS & EXPERIENCES

We are looking for a seasoned expert who combines hands-on laboratory discipline with a deep theoretical understanding of wet bench dynamics.

Requirements

• Education:MinimumBachelor’s Degreein Chemical Engineering, Materials Science, Chemistry, or a related Engineering discipline.
• Experience:5 to 10 yearsof direct experience in semiconductor process development, with a heavy emphasis on wet station technologies.
• Wet Process Mastery:Proven track record inElectroless and Electrolytic plating(experience with NiPdAu chemistry and stabilizer management is a significant plus).
• Deep expertise inWet EtchingandWafer Cleaning(SC1/SC2, SPM, and advanced solvent chemistries).
• Hands-on experience withResist Strippingand surface preparation for advanced packaging or Front-End-Of-Line (FEOL) applications.
• Analytical Rigor:Proficiency inDesign of Experiments (DOE)and Statistical Process Control (SPC).Ability to interpret complex material characterization data to identify chemical stratification or surface poisoning issues.
• Soft Skills:Strong communication skills to present R&D findings to stakeholders and the "grit" to solve challenges.
