RF Device Characterization Engineer 

What you will do

The deployment of millimeter-wave 5G and 6G radio systems pushes the requirements on device performance further than ever before. Achieving very high-power efficiency at mmWave frequencies is critical for such applications. Technology must be adapted to reduce the power consumption of high-power amplifiers. Although compound semiconductors technologies promise to meet these goals, their low-cost fabrication on a CMOS compatible platform remains challenging. In this context, innovative III-V and GaN transistors compatible with large-scale Si wafers are currently being developed at imec. In order to optimize the technology developments, precise transistor characterization and modeling are required over a wide range of frequencies and power level.  The RF nonlinear behaviour is particularly important and challenging.  

In this position, you will be responsible for the electrical characterization of advanced transistors up to sub-THz frequencies.  You will use state-of-the-art equipment (vector network analyzers, large-signal network analyzers, load-pull, real-time oscilloscope,...) and automate processes. You will develop new testbenches and design experiments taking into account the specific properties of the devices-under-test (e.g., slow transient arising from thermal and trap states). You will work on calibration techniques and de-embedding methods for accurate on-wafer measurements up to sub-THz frequencies. You will propose techniques to minimize measurements uncertainties. 

Being part of imec’s RF device integration and modelling team, you will interact with RF experts and device engineers. 

What we do for you

We offer you the opportunity to join one of the world’s premier research centers in nanotechnology at its headquarters in Leuven, Belgium.
