Abstract

In this work, the trap generation behaviors under off-state TDDB are comprehensively studied for advanced FinFETs. The results show that electron traps in the high-<inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula> gate dielectric layer are responsible for the gate dielectric breakdown. In addition, the correlation between the spatial distribution of traps and the stress electric field is experimentally established and further validated using the matrix percolation model.
