  • Influence of sample thickness of low-density polyethylene film on packet-like charges behavior and dielectric breakdown

    Many research works have been reported on space charge accumulation characteristic in polyethylene based materials, which are used as a power cable insulating material. In these reports, some of them show the relationship between the space charge accumulation and dielectric breakdown under DC high electric field. For example, Matsui et al, showed that the packet-like charges injected into Low-Density Polyethylene (LDPE) film with thickness of ca.150 μm lead to the dielectric breakdown under DC high electric field. The report said that the dielectric breakdown occurred within 30 minutes under various applied DC electric field of more than 200 kV/mm. Furthermore, the electric field in the material reached to about 550 kV/mm. It is considered that the dielectric breakdown in the LDPE is caused by an enhancement of the electric field locally. However, in our research, the dielectric breakdown was not observed in relatively thin LDPE film with a 30 μm-thick. In this study, we measured the space charge distribution in thin LDPE film of 30 μm-thick. The measurement was carried out using an improved PEA (Pulsed Electro-Acoustic) system with the positional resolution of less than 3 μm. Using this improved system, we investigated the influence of sample thickness on packet-like charges behavior and dielectric breakdown. As the results, we found while the packet-like charges behavior in 30 μm LDPE films showed a similar tendency to Matsui's results, the dielectric breakdown was not observed in the thin sample. In this report, we tried to understand the influence of the sample thickness on the dielectric breakdown.

  • TDDB-emerald: A methodology for estimating memory reliability degradation resulting from time-dependent dielectric breakdown

    One of the major wearout mechanisms in modern microprocessors is time- dependent dielectric breakdown. Beyond the 28 nm technology node, time- dependent dielectric breakdown from not only the frontend-of-line and backend- of-line, but also the middle-of-line, yields a significant number of failures in VLSI circuits. In this paper, we investigate the impact of time-dependent dielectric breakdown in all phases of fabrication processes (i.e., frontend/middle/backend-of-line) on static random access memory in modern microprocessors. With the analysis of potential resistive short defect locations in a memory cell, we propose a methodology for accurately estimating memory reliability degraded by time-dependent dielectric breakdown. Using activity profiles and device-level wearout models, we also propose a method for statistically estimating the lifetime of a memory cell. Using the simulation methodology, we investigate the lifetime degradation of a memory system while taking all three time-dependent dielectric breakdown mechanisms into account.

  • Dielectric breakdown characteristics of alumina

    The AC 50 Hz sine dielectric breakdown of alumina ceramics versus thickness (0.127 to 2.54 mm) and purity (92%, 96% and 99.5%) was investigated. The results have shown that the dielectric strength decreases with the thickness and increases with the purity. Furthermore, the investigation of the failure morphology using the scanning electron microscopy (SEM) show for each specimens submitted to breakdown the presence of a canal terminated by a crater at the surface. This crater is resulting from the extraction and ejection of the matter during the breakdown process caused by the intensification of the local electric stress. An evolution of the crater size versus the sample thickness have also been observed. The analysis of the experimental results and the SEM observations confirm that the built up of the crater is a crucial step in dielectric breakdown process and the mechanism best suited to describe the dielectric breakdown in these materials is based on an electromechanical one.

  • Dielectric breakdown of gamma-ray irradiated epoxy resin in crossed field

    This paper describes the effects of magnetic field and low pressure on dielectric breakdown of gamma-ray irradiated epoxy resin. The experiment was carried out by applying a dc pulse voltage with the intervals adjusted from 5 ms to 10 ms. The samples were irradiated in air up to 100 kGy and then up to 1000 kGy with a dose rate of 10 kGy/h by using a <sup>60</sup>Co gamma-source. The magnetic flux density of the magnetic filed was 495 mT and the pressure was reduced to 1 kPa. The effects of the pressure, magnetic filed and gamma- ray irradiation on the time to dielectric breakdown and discharge quantity were studied. Obtained results revealed that the time to dielectric breakdown increased with increasing the total dose of radiation and was delayed by decreasing the pressure and increasing the magnetic field. The discharge quantity decreased with increasing the total dose of gamma-ray irradiation and increasing the magnetic field, but increased with decreasing the pressure.

  • Condition evaluation of power transformers using dissolved gas analysis and dielectric breakdown voltage test

    This paper proposes the techniques for evaluating power transformer condition based on frequently updated test results. According to planned maintenance, insulation oil is regularly sampled and analyzed in laboratory to determine problems inside main tank by dissolved gas analysis as well as dielectric breakdown voltage test to determine dielectric property of the oil. The dissolved gas analysis is firstly compared with limit values of gases in IEC standard. If values of gases exceed normal condition, the dissolved gases are analyzed by using Duval triangle while dielectric breakdown voltage criterion is reference with the IEC standard. These two methods are subsequently implemented in Microsoft Excel and Visual Basic for Application to evaluate the condition of power transformer and dielectric strength of insulating oil.

  • Effect of relative humidity on surface dielectric breakdown of epoxy based nanocomposites under repeated pulses

    In this work, epoxy based nanocomposites was prepared to investigate the effect of relative humidity on surface dielectric breakdown under repeated pulses. Two kinds of inorganic nano particles, i.e. silica and alumina, were used as fillers. The experiment was carried out at room temperature with relative humidity varied from 50% to 90%. A pair of needle-plate electrodes that was tightly pressed on the sample surface made the electrode pattern. By applying repeated pulses with voltage magnitude of -30 kV at a frequency of 100 Hz between the electrodes, surface discharge was initiated and thereby the dielectric breakdown was allowed. The time from voltage application to the formation of the breakdown was measured. Obtained results indicated that the time to the breakdown was strongly dependent upon the concentration of nano particle, which was also varied as a function of the relative humidity. It is suggested that behaviors of water absorption and charge transportation are changed as a consequence of the addition of nano particles as compared to the neat epoxy, which results in the variation in the resistance to the breakdown of epoxy resin.

  • Time-Dependent Dielectric Breakdown of $\hbox{La}_{2} \hbox{O}_{3}$-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 beta of breakdown distribution is in the range of 0.87-1.19, and it is independent on capacitor areas and stress conditions. Moreover, field dependence of TBD and stress- induced leakage current strongly suggest that the E-model is more applicable to explain in TDDB of La-incorporated high-k dielectric in Hf-based high-k/metal gate stack structure.

  • Dielectric breakdown of an epoxy/quartz composite and a nanostructured epoxy/quartz/Montmorillonite composite. Influence of electrode geometry

    Microcomposites epoxies are widely used as high voltage insulation. A new way to improve such materials is to add nanoparticles to the epoxy matrix, thus forming a nanostructured microcomposite. For this study, epoxy composites films filled with 60% wt of quartz microparticles were prepared, reinforced or not by 0.45% wt of organically modified Montmorillonite C30B. The dielectric breakdown strength of the samples was studied using two types of electrode and the statistical analysis of the breakdown data was performed using the Weibull distribution. The use of different electrode geometries implied a different distribution of the electrical field magnitude both in the dielectric sample and in the surrounding medium. Rigid films with a typical thickness of 1 mm are set between electrodes embedded in oil and AC voltage was increased at a constant rate until breakdown occurs. No significant difference was found in the breakdown data for microcomposites and nanostructured composites. The use of a more uniform electrical field decreases slightly the measured dielectric breakdown strength. The shape factor associated with the distribution dispersion is unchanged for both studied cases, but very low compared to classical industrial materials. Finally, the thus obtained results warrant the use of smaller-area samples if non-uniform field conditions are used.

  • Dielectric Breakdown in Underoxidized Magnetic Tunnel Junctions: Dependence on Oxidation Time and Area

    Magnetic tunnel junctions (MTJs) with partially oxidized 9-Aring AlO<sub>x</sub>-barriers were recently shown to have the necessary characteristics to be used as magnetoresistive sensors in high-density storage devices. Here we study dielectric breakdown in such underoxidized MTJs, focusing on its dependence on tunnel junction area and oxidation time. A clear relation between breakdown mechanism and junction area is observed for the MTJs with the highest studied oxidation time: samples with large areas fail usually due to extrinsic causes (characterized by a smooth resistance decrease at dielectric breakdown). Small area junctions fail mainly through an intrinsic mechanism (sharp resistance decrease at breakdown). However, this dependence changes for lower oxidation times, with extrinsic breakdown becoming dominant. In fact, in the extremely underoxidized magnetic tunnel junctions, failure is exclusively related with extrinsic causes, independently of MTJ area. These results are related with the presence of defects in the barrier (weak spots that lead to intrinsic breakdown) and of metallic unoxidized Al nanoconstrictions (leading to extrinsic breakdown)

  • Resistance switching phenomenon in nano-conduction path formed by dielectric breakdown

The ferromagnetic NCP was formed by the use of dielectric breakdown of insulator (SiO<sub>2</sub>) concomitant with an introduction of ferromagnetic atoms into NCP by electromigration.
