YOUR ROLE
Responsibilities
As a
SeniorWets 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: Minimum Bachelor's Degree in Chemical Engineering, Materials Science, Chemistry, or a related Engineering discipline.
- Experience: 5 to 10 years of direct experience in semiconductor process development, with a heavy emphasis on wet station technologies.
- Wet Process Mastery: * Proven track record in Electroless and Electrolytic plating (experience with NiPdAu chemistry and stabilizer management is a significant plus).
- Deep expertise in Wet Etching and Wafer Cleaning (SC1/SC2, SPM, and advanced solvent chemistries).
- Hands-on experience with Resist Stripping and surface preparation for advanced packaging or Front-End-Of-Line (FEOL) applications.
- Analytical Rigor: Proficiency in Design 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.
