Job summary

AAC Technologies Pte. Ltd. located in Singapore seeks a MEMS/CMOS process engineer to lead process integration across the full product lifecycle for MEMS microphone products.

You will translate device designs into robust manufacturing processes focusing on DFM, cost, and reliability. Collaborate with foundry partners to develop and optimize MEMS processes (DRIE, deposition, lithography, release). Drive yield improvements through FA and RCA, interface with design, packaging, reliability and test

Qualifications

• Bachelor’s degree in Electrical/Electronic Engineering, Microelectronics, Materials Science, Mechanical Engineering, or a related field.
• Minimum 1 year of 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 (SEM, AFM), along with DOE and data analysis tools (JMP, Python).

Responsibilities

• Lead process integration across the full product lifecycle from concept to mass production for MEMS microphone products.
• Translate device designs into robust and scalable manufacturing processes with 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.
