Job description

Job Summary:

• Location: Tampines Industrial Crescent




• Salary: Basic up to $5500 + AWS




• Working Hours: 5 days per week
  

Job Responsibilities:

• Lead process integration across the full product lifecycle, from concept, prototyping to mass production for MEMS microphone products.




• Translate device designs into robust and scalable manufacturing processes with strong focus on DFM, cost, and reliability.




• Collaborate with foundry partners to develop, qualify, and optimize key MEMS processes (e.g. DRIE, deposition, lithography, release).




• Drive yield improvement and resolve process-related issues through failure analysis (FA) and root cause analysis (RCA).




• Act as the technical interface between foundries and internal teams (design, packaging, reliability, test) to ensure smooth development.




• Prepare and maintain process documentation including process flows, FMEA, control plans, and qualification reports.




• Support R&D activities, including experimentation, new materials/process development, and technology roadmap initiatives.




• Lead and support NPI activities, including Lab-to-Fab and Fab-to-Fab transfers, ensuring process readiness and yield performance.
  

Job Requirements:

• Bachelor’s degree in Electrical/Electronic Engineering, Microelectronics, Materials Science, Mechanical Engineering, or a related field.




• Minimum 1 year of experience in MEMS/CMOS processing, semiconductor fabrication, or microfabrication R&D.




• Knowledge of MEMS devices (e.g., microphones, sensors) and key fabrication processes such as DRIE, LPCVD/PECVD, lithography, and release techniques.




• Hands-on experience with cleanroom operations, metrology, and failure analysis tools (e.g., SEM, AFM), along with DOE and data analysis tools (e.g., JMP, Python).
