Ultra-dense co-integration of FeFETs and CMOS logic enabling very-fine grained Logic-in-Memory

, 2022
Ferroelectric field-effect transistors (FeFET) based on hafnium oxide offer great opportunities for Logic-in-Memory applications, due to their natural ability to combine logic (transistor) and memory (ferroelectric material), their low-power operation ...

Deconvoluting charge trapping and nucleation interplay in FeFETs: Kinetics and Reliability

, 2018
Discovery of ferroelectric (FE) behavior in HfO 2 removed the compatibility roadblocks between the state-of-the-art CMOS and FE memories. Even though FE FETs (FeFETs) are scaled into 22 nm nodes and beyond, the limits of the technology as well as the ...

Recent Progress in Downsizing FeFETs for Fe-NAND Application

, 2011
Sub-micrometer ferroelectric-gate field-effect transistors (FeFETs) of 0.56 μm and 0.50 μm gate lengths were successfully fabricated for Fe-NAND cells. Gate stacks of the FeFETs were Pt/SrBi2Ta2O9(SBT)/Hf-Al-O/Si.
