Missions

The objective of the postdoctoral project will be to explore circuit-technology co-optimization (DTCO) approaches for next-generation memory bitcells and computing circuits based on ferroelectric materials. This project will focus on the use of physics-based compact models as well as system-level optimization and simulation tools to analyze critical trade-offs in terms of performance, endurance, and reliability of ferroelectric devices.

Activités

The recruited postdoctoral researcher will develop and apply DTCO methodologies in order to:
- Model the behavior of ferroelectric bitcells using Verilog-A compact models (e.g., calibrated HZO FeCap/FeMFET models) that incorporate partial polarization switching, thermal effects, and variability (Monte Carlo analyses)
- Quantify system-level trade-offs in ferroelectric near-memory computing architectures, including:
o Endurance-speed limitations
o Voltage-time dynamics of polarization switching
o Programming energy versus memory window optimization
- Co-optimize device-circuit interactions through array-level simulations to assess model convergence, parasitic effects, and performance-power-area metrics
More broadly, this work will contribute to the enhancement of the open-source DTCO ecosystem via the CHOOSE platform of the PEPR Électronique initiative. The recruited researcher will participate in coordination meetings with partners from the PEPR Électronique-FerroFutures project and will contribute to the dissemination and visibility of the project through publications in international journals and conferences. They may also be involved in supervising PhD students and/or Master-level interns.

Compétences

The selected candidate must hold a PhD in microelectronics or a related field, and demonstrate proven experience in at least one of the following fields:
- Design and simulation of microelectronic circuits (Verilog-A implementation, use of SPICE-type electrical simulation tools)
- Statistical and dynamic analysis of variability
- Development or use of DTCO/STCO methods and tools applied to memory or logic technologies
