چکیده

The effects of a current-limited breakdown (BD) on the post-BD current of MOS capacitors with a thin high-k dielectric stack have been analysed. A strong current reduction after BD and, consequently, a partial recovery of the insulating properties of the dielectric stack is observed. The similarities with the Resistive Switching phenomenon observed in MIM structures for memory applications are discussed.

Time-dependent dielectric breakdown (TDDB) distribution in n-MOSFET with HfSiON gate dielectrics under DC and AC stressing

This paper discusses time-dependent dielectric breakdown (TDDB) in n-FETs with HfSiON gate stacks under various stress conditions. It was found that the slope of Weibull distribution of Tbd, Weibull β, changes with stress conditions, namely, DC stress, unipolar AC stress and bipolar AC stresses. On the other hand, the time evolution component of stress-induced leakage current (SILC) was not cha...

Reliability issues of double gate dielectric stacks based on hafnium dioxide (HfO2) layers for non-volatile semiconductor memory (NVSM) applications

In this study, we present selected reliability issues of double gate dielectric stacks for non-volatile semiconductor memory (NVSM) applications. Fabricated gate structures were consisted of PECVD silicon oxynitride layer (SiOxNy) as the pedestal layer and hafnium dioxide layer (HfO2) as the top gate dielectric. In the course of this work, obtained MIS structures were investigated by means of c...

Characterization of Charge Trapping and Dielectric Breakdown of HfAlOx/SiON Dielectric Gate Stack

1 Introduction Hf-based silicates and aluminates showing good thermal stability [1] and favorable energy-band alignment [2] have been intensively studied as most promising alternative gate dielectrics. Despite a number of efforts to improve the dielectric properties of such high-k thin films, reliability issues such as charge trapping and dielectric wear-out are still matters of research [3, 4]...

Time-Dependent Dielectric Breakdown of La2O3-Doped High-k/Metal Gate Stacked NMOSFETs

Time-dependent dielectric breakdown (TDDB) characteristics of La2O3-doped high-k dielectric in Hf-based high-k/TaN metal gate stack were studied. Unlike the abrupt breakdown in the conventional SiO2, dielectric breakdown behaviors of La-incorporated HfON and HfSiON dielectrics show progressive breakdown characteristics. Moreover, the extracted Weibull slope β of breakdown distribution is in the...

Advanced high-k dielectric stacks with polySi and metal gates: Recent progress and current challenges

The paper reviews our recent progress and current challenges in implementing advanced gate stacks composed of high-j dielectric materials and metal gates in mainstream Si CMOS technology. In particular, we address stacks of doped polySi gate electrodes on ultrathin layers of high-j dielectrics, dual-workfunction metal-gate technology, and fully silicided gates. Materials and device characteriza...
