Device Engineer

About the role

STMicroelectronics is seeking a Device Engineer to drive yield and D0 improvements for its semiconductor technologies. You will analyse silicon data, support technology and product development, and work on parametric yield and reliability enhancements.

Key responsibilities

• Analyse zero‑yield and low‑yield wafers to identify root causes and implement yield improvement actions.
• Collaborate with module teams to resolve process issues and ensure smooth production flow to meet delivery commitments.
• Characterise process windows to achieve robust manufacturing performance.
• Liaise with division teams (ADG, AMS, AMG, MDG) for technology and product transfer activities within defined timelines.
• Participate in weekly conference calls for yield/D0 updates and maintain the yield master plan.
• Conduct MRB meetings to discuss disposition of SBL lots on a weekly basis.

Required profile

• Strong knowledge of semiconductor device physics (MOSFETs, BJTs, diodes, power devices).
• Experience with electrical characterisation equipment such as parametric testers, curve tracers, SMUs, LCR meters and probers.
• Basic understanding of front‑end semiconductor manufacturing processes (diffusion, implantation, oxidation, lithography, etch, metallisation).
• Data‑analysis proficiency using tools like JMP or Excel.
• Excellent written and spoken English communication skills.
