Wafer Level Packaging Technology Expert

Technology Expert for RF Heterogeneous Integration of III-V / CMOS / Antenna arrays.

Who we are

The Imec Advanced-RF (ARF) group in Leuven enjoys a world-class reputation in advanced communication and radar and millimeter wave sensing systems. In these fields, the group has a vertical system approach: our expertise ranges from antenna, frontend, baseband, analog-to-digital conversion to algorithms and systems. The group also combines innovative communication and sensing technologies that unleash the full potential of future smart cities, smart health and internet of things (IoT). Furthermore, research is also done in the fields of advanced wireline communication, future RF technologies, mmwave sensing for lifesciences, mmwave imaging, …  

What you will do

Next generation communication and radar systems will operate at frequencies beyond 100 GHz. At such high frequencies, traditional interconnect solutions based on PCBs incur excessively high loss and leakage of signal. Furthermore, larger antenna arrays are needed to overcome higher path loss, low amplification, and low absolute power from transistors. Heterogeneous integration of different transistor technologies and passive components is essential to meet link budget and high data rate requirements at these frequencies. 
 
Your main expertise should be wafer level packaging technologies with a focus on mm-wave and sub-terahertz applications. Knowledge of both technology and design aspects of mm-wave transitions and their co-design with RF circuits will be your main responsibility. Literature survey and keeping an up-to-date list of recent (academic and industry) developments in this field will be an additional task.  
 
Your tasks will include: 

• EM Simulations of RF interconnects – flip-chip, embedded-chip, passive components
• Circuit simulation and co-design of active building blocks (e.g., amplifier, oscillator, frequency conversion) with wafer scale packages for 100 - 300 GHz
• Simulation and Benchmarking with advanced PCB technologies like IC Substrate, Substrate like PCBs and Scaled organic packages
• Heterogeneous integration of III-V and CMOS at wafer, die or package level
• System Technology Co-optimization - Work with 3D technology experts to define technology flows where both manufacturability and EM performance are co-optimized
