ESSDERC 2017 Best Regular Paper Award

Namlab and TU Dresden authors were selected for the ESSDERC 2017 Best Regular Paper Award for a paper entitled “Anti-ferroelectric ZrO2: an enabler for Low Power Non-volatile 1T-1C and 1T Random Access Memories”, authored by M. Pešić, M. Hoffmann, C. Richter, S. Slesazeck, T. Kämpfe, L. M. Eng, T. Mikolajick and U. Schroeder

Abstract of the ESSDERC 2017 paper:

Recently, it was demonstrated that an asymmetric DRAM  capacitor  stack  can  introduce  non-volatility  and  at  the same time outperform ferroelectric HfO2  based FeRAM in terms of cycle endurance. With the present work, we provide an in-depth study of the underlying mechanisms and perform a comprehensive retention study that characterizes ferroelectric memories. Piezoelectric force microscopy is applied to prove the ultimate scalability of the proposed concept beyond capacitor based application. Finally, switching density plots reveal a much lower device to device variability and high switching uniformity with respect to ferroelectric HfO2 based films

Novel High k Application Workshop 2017

NaMLab invites to the Novel High-k Application Workshop on March 9th and 10th, 2017. New challenges offered by the application of high-k dielectric materials in micro– and nanoelectronics will be discussed by more than 80 participants from industry, research institutes and universities. One main focus will be on the ferroelectric properties of HfO2.

NaMLab created with the workshop a stimulating platform for application-oriented scientist to exchange ideas and discuss latest experimental results on MIM-capacitors, process technology, leakage & reliability as well as characterization of high-k dielectrics integrated in silicon based micro– and nanoelectronics. The ferroelectric properties of doped HfO2 and ZrO2 were discovered 10 years ago. On the second day of the workshop, root causes for the formation of this so far unknown phase will be discussed.
