For the first time, the breakdown path induced by BTI stress can be traced from the RTN measurement. It was demonstrated on advanced high-k metal gate CMOS devices. RTN traps in the dielectric layers can be labeled as a pointer to trace the breakdown path. It was found that breakdown path tends to grow from the interface of HK/IL or IL/Si which is the most defective region. Two types of breakdown...
A novel anti-ESD RF SOI LIGBT with buried P-type layer (BPL) was proposed for improvement of its forward block characteristic. The proposed anti-ESD BPL RF SOI LIGBT consists of an additional buried P-type layer inserted between buried oxide layer and N-drift region based on the conventional RF SOI LIGBT structure and a built-in self-ESD-protection structure introduced in P-well region. When the proposed...
Dielectric breakdown in advanced gate stacks in state-of-the-art Si nanoelectronic devices has been one of the key front-end reliability concerns for further CMOS technology downscaling. In this paper, we present the latest findings in using physical analysis techniques such as transmission electron microscopy (TEM)/electron energy loss spectroscopy (EELS)/energy dispersive X-ray spectroscopy (EDS),...
Reliability study of high-κ (HK) gate dielectric based transistors has become imperative for the current and future CMOS technology nodes as the industry shifts towards replacement of conventional silicon oxynitride (SiON) with hafnium-based oxides. One of the key requirements of any oxide reliability study is a quantitative assessment of the time dependent dielectric breakdown (TDDB) lifetime using...
In order to achieve aggressive scaling of the equivalent oxide thickness (EOT) and simultaneously reduce leakage currents in logic devices, silicon-based oxides (SiON / SiO2) have been replaced by physically thicker high-κ transition metal oxide thin films by many manufacturers starting from the 45 nm technology node. CMOS process compatibility, integration and reliability are the key issues to address...
A TDDB reliability experiment was performed on interdigitated comb structures with intentionally severe line-edge roughness and the results were then compared to a simple theoretical model. It is seen that for the case studied, the predictions of the model do not compare well to the experimental data, but that for some observed cases the effect of reducing spacing between lines is so strong that more...
