Introduction

The Feature-Rich CMOS Business Unit at GlobalFoundries is seeking a motivated Junior CMOS Image Sensor Device Engineer to support our next-generation imaging and device-technology development. This role is based in Leuven, Belgium, where you will work embedded within IMEC’s world-class research environment, collaborating closely with IMEC scientists and GlobalFoundries device, integration, circuit, and TCAD teams. You will contribute to the development and optimization of photodiodes, pinned photodiodes (PPDs), SPAD/SiPM pixels, and CIS analog readout structures, enabling future imaging platforms across GF’s Feature-Rich CMOS technologies. This position is ideal for engineers passionate about imaging device physics, semiconductor R&D, and cross-organizational collaboration, including those considering future doctoral studies.

Your Job

• Support device and pixel development for photodiodes, PPDs, SPAD/SiPM pixels, and related CIS device structures.

• Collaborate with IMEC teams and GlobalFoundries Feature-Rich CMOS device, FEoL Integration, and platform groups to identify and drive CIS and SPAD sensing technologies.

• Define, design, and evaluate device/pixel test structures, including electro-optical test methodologies.

• Perform electro-optical and electrical characterization, analyzing key device KPIs such as quantum efficiency, conversion gain, dark current, noise behavior, and CIS as well as SPAD-specific metrics.

• Work with TCAD and compact-modeling teams on simulation-based device predictions, experiment planning, and model correlation.

• Interface with analog readout designers to support low-noise CDS/ADC architectures and pixel/readout co-design.

• Contribute to DTCO, DOE-driven explorations, and structured development cycles from concept to silicon validation.

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Applied Physics, Semiconductor Engineering, or related fields.

• Strong interest in CMOS image sensing, photodiodes, CIS/SPAD pixels, and semiconductor device physics.

• Understanding of semiconductor fundamentals and optical interactions.

• Basic skills in Python or MATLAB for data processing; proficiency with Excel and PowerPoint.

• Strong communication and teamwork skills in a cross-functional, international environment.

• English language proficiency at C1 level.
   

Preferred Qualifications

• Hands-on experience with electro-optical measurements, pixel characterization, or sensor-level testing.

• Familiarity with TCAD tools (Synopsys, Silvaco), optical simulation, or VLSI layout basics.

• Understanding of analog readout circuits, especially CDS/ADC design fundamentals and low-noise device-circuit interactions.

• Experience with structured problem-solving tools (DOE, FMEA, etc.).

Why This Role is Unique

• Work on-site at IMEC, one of the world’s top research centers for semiconductor and imaging technologies.

• Contribute directly to GlobalFoundries’ Feature-Rich CMOS Business Unit, enabling differentiated imaging solutions across a global technology portfolio.

• Collaborate across the full imaging pipeline: device → process → pixel → readout → modeling.

• Engage with cutting-edge innovations in PPD design, SPAD technology, and ultra-low-noise readout circuits.

• Excellent opportunity for early-career engineers aiming to build deep expertise or pursue a future PhD in semiconductor device physics or imaging.
