WebLaser annealing is performed to crystallize a 10 nm thick non-doped hafnium dioxide (HfO2) thin film. The influence of the laser annealing dwell time on the crystallization process is investigated considering the Gibbs free energy diagram of various HfO2 phases (i.e. monoclinic, cubic, tetragonal, and orthorhombic). Progressive phase transformations as … WebAbstract: We report the realization of a HfO 2-based dielectric with the highest permittivity (~68) among all the reported works, approaching their theoretical limit of 70 [Fig. 1].This …
WebThe HfO2 permittivity, equivalent oxide thickness (EOT), flat-band voltage (Vfb) and total charge (Qt) were extracted from the CV response at high frequency taking into account the HfO2 and SiO2 thicknesses obtained by XRR. The calculated permittivity values were in the range 7–13, i.e. lower than theoretical values for the monoclinic phase.
