Research & development - Leuven | More than two weeks ago
There has been a tremendous advancement in the domain of wireless communication technology, with the recent introduction of 6G and RF/mmWave standards for automotive, IoT and near field communication in the frequency range of 30 – 300 GHz and higher. The requirements of high scalability and low-power losses are driving the research focus towards the use of advanced GaN-HEMT devices and InP-based Heterojunction Bipolar Transistors (HBTs).
One of the major hurdles of the large-scale integration of these high-performance RF devices with the standard-CMOS process flows is their poor reliability and operating lifetime. The inherently high defectivity of these devices severely limits the high-frequency performance metrics such as, threshold and maximum oscillation frequency (ft/fmax), parasitic losses, dynamic on-Resistance (RON), Pout and PAE. Therefore, obtaining a fundamental understanding of the kinetics of charge trapping in the defects is crucial for enhancing device performance and enabling the future 6G/mmWave technologies.
You will work in the front-end reliability team at imec. You will characterize new devices using standard DC characterizations and develop degradation models for new GaN and/or InP based transistors. This activity will englobe standard DC characterization to and, on a later stage, measurements within high frequency operating regimes (30GHz – 300GHz). The device RON-dispersion, Pout/PAE degradation, and drifts in ft/fmax must be characterized and comprehensive reliability models must be developed. You will aim to ultimately transfer these fundamental insights for improved circuit- and system-level design of RF-FEMs (front-end-modules) such as power amplifiers (PAs), low-noise amplifiers (LNAs) and RF switches.
We offer you the opportunity to join one of the world’s premier research centers in nanotechnology at its headquarters in Leuven, Belgium.
