Postdoctoral Researcher: The role of mechanical stress in aging of advanced CMOS devices 

What you will do

The role of mechanical stress on device reliability is expected to be enhanced in future VLSI CMOS nodes due to the adoption of novel technological solutions, as, e.g., the introduction of (Si)Ge either as a channel material, or as a sacrificial layer for the fabrication of Si nanosheets. 3D integration has been also envisioned as a disruptive approach to continue increasing CMOS functionality per die area by stacking multiple transistor layers on top of each other. The reduced thermal budget allowed in 3D fabrication is unable to relax the large compressive strains in the transistor gate oxide, resulting in large oxide defect densities and suboptimal device reliability. The relation between fabrication thermal budget, mechanical strain in the semiconductor channel and in the oxide, and oxide defect properties needs to be thoroughly investigated.  As the researcher, you will
  • Study the reliability of novel devices, i.e., how the device parameters change as a function of time under combined electrical and mechanical stress
  • Use cutting-edge small-area devices to study properties of defects at the single defect level, such as their individual capture and emission times
  • Collaborate with theorists to identify the links with first-principles material properties, such as chemical bonds
  • Improve the test procedures and instrumentation, develop lifetime projection methodologies for device aging mechanisms under mechanical stress, and propose optimal technology integration strategies

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. With your talent, passion and expertise, you’ll become part of a team that makes the impossible possible. Together, we shape the technology that will determine the society of tomorrow. 

We are proud of our open, multicultural, and informal working environment with ample possibilities to take initiative and show responsibility. We commit to supporting and guiding you in this process; not only with words but also with tangible actions. Through imec.academy, 'our corporate university', we actively invest in your development to further your technical and personal growth. 

We are aware that your valuable contribution makes imec a top player in its field. Your energy and commitment are therefore appreciated by means of a competitive salary with many fringe benefits

Who you are

  • Inquisitive, research-oriented, hard-working, self-starter
  • You have a PhD in electrical engineering, physics, or material sciences
  • You have an in-depth knowledge/expertise of semiconductor devices
  • You have working knowledge of semiconductor device reliability and surface chemistry 
  • You are experienced with mechanical design, setting up and running complex experiments, and data analysis
This postdoctoral position is funded by imec through KU Leuven. Because of the specific financing statute which targets international mobility for postdocs, only candidates who did not stay or work/study in Belgium for more than 24 months in the past 3 years can be considered for the position (short stays such as holiday, participation in conferences, etc. are not taken into account).
