Senior
Wets 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:
