Abstract:

Silicon-based dielectrics (SiO2, Si3N4, SiOxNy etc.) have been widely used as the key dielectrics in the manufacturing of silicon integrated circuits (ICs) and virtually all other semiconductor devices. Dielectrics having a value of dielectric constant k × 8.854 F/cm more than that of silicon nitride (k > 7) are classified as high dielectric constant materials, while those with a value of k less than the dielectric constant of silicon dioxide (k < 3.9) are classified as the low dielectric constant materials. The minimum value of (k) is one for air. The highest value of k has been reporte

Abstract:

Magnetic nanofluids are increasingly finding new applications. They can be employed as liquid dielectrics. The advantage of having a liquid dielectric is that high dielectric constant can be achieved by a judicious choice of the base liquid. The dielectric constant can be tuned with the help of an external magnetic field too. Superparamagnetic iron oxide nanoparticles were dispersed in polar carriers, namely water, polyvinyl alcohol, ethylene glycol, and a nonpolar carrier like kerosene to obtain stable magnetic fluids after ensuring the crystallographic phase purity along with appropriate mag

Abstract:

The effect of plasma on the radiation characteristics of curved rectangular microstrip antenna is studied by means of a new plasma simulation technique. Unlike previous techniques [1,2], a relative index of refraction less than unity is obtained by representing free space with a high dielectric constant sodium chloride powder and plasma by a medium of lower dielectric constant (air). A wide range of dielectric constants of simulated plasma could be possible with this technique using solid dielectrics instead of liquids. It is observed that the resonance frequency is not affected by the curvatu

Abstract:

Materials exhibiting high dielectric constant (k) values find applications in capacitors, gate dielectrics, dielectric elastomers, energy storage device, while materials with low dielectric constant are required in electronic packaging and other such applications. Traditionally, high k value materials are associated with high dielectric losses, frequency-dependent dielectric behavior, and high loading of a filler. Materials with low k possess a low thermal conductivity. This creates the new challenges in the development of dielectric materials in both kinds of applications. Use of high dielect

Low-k organic polymers such as polytetrafluoroethylene (PTFE) are promising materials for use as interlayer dielectrics (ILD) because their dielectric constants are generally lower than those of inorganic materials. However poor adhesion with Si substrates, poor thermal stability, and production difficulties have hindered their use in microelectronics.On the other hand, plasma-enhanced chemical vapor deposition (PECVD) of polymer films (plasma polymerization) has many advantages that help to overcome these problems.

Materials with a low dielectric constant are required as interlayer dielectrics for the on-chip interconnection of ultra-large-scale integration devices to provide high speed, low dynamic power dissipation and low cross-talk noise.

Integration of such materials into microelectronic circuits, however, poses a number of challenges, as the materials must meet strict requirements in terms of properties and reliability.

Abstract:

Abstract Organic–inorganic hybrid dielectrics composed of nanoscale ceramic fillers in polymer matrices have attracted considerable attention because they can overcome the inherent limitations such as the low dielectric constant, high dielectric loss, and low film density associated with mechanically flexible pristine polymer materials. Barium titanate (BaTiO3), a representative perovskite-based material with a high permittivity, is suitable for applications as nanofillers in nanocomposite dielectrics. X-ray diffraction combined with Raman analysis suggest that a two-step hydrothermal synthesi

Abstract:

The emergence of micro and nano-based inorganic oxide fillers with optimal filler-loadings further enhances the required insulation characteristics of neat epoxy. During manufacturing and service application, insulators and dielectrics face mechanical stresses which may alter their basic characteristics. Keeping this in mind, the facts’ influence of mechanical stresses and fillers on dielectric properties of polymeric insulators of two epoxy/silica composites were fabricated and thoroughly analyzed for dielectric characteristics under ramped mechanical compressions relative to the unfilled sam

Flexible polymer-based composites exhibiting high dielectric constant as well as low dielectric loss have been intensively investigated for their potential utilization in electronics and electricity industry and energy storage. Resulting from the polar -CN on the side chain, polyarylene ether nitrile (PEN) shows relatively high dielectric constant which has been extensively investigated as one of the hot spots as dielectric materials. However, the dielectric constant of PEN is still much lower than the ceramic dielectrics such as BaTiO3, TiO2, and Al2O3. In this review, recent and in-progress

The frequency dependence of dielectric constant, dielectric loss factor and conductivity are studied for five edible oils in the frequency range 100 kHz to 13 MHz at different temperatures using frequency domain spectroscopy. The dielectric constant is found similar for all the samples and in agreement with the previous reports. The dielectric loss is low (<0.01) except for the virgin olive oil with value of 0.05. Dielectric loss peak frequency is at 4 MHz for corn oil and around 5.2 MHz for the others. At this frequency conductivity is of the order of 10-7-10-9 S/cm, and decreases with tem

Optical constants such as refractive index, absorption coefficient, extinction coefficient and the real (εr) and imaginary (εi) components of the dielectric constant for CuSO4.5H2O (10-100%) concentrations were determined from the visible light Optical transmission data. Results of visible light transmission analysis in the solutions have shown that in dilute solutions the dielectric constant real and imaginary parts are linear. The addition of dissolved cu+2 and so4-2 ions above (80%) concentrations results in a drop in dielectric constant.

Upcoming advancements in flexible technology require mechanically compliant dielectric materials. Current dielectrics have either high dielectric constant, K (e.g., metal oxides) or good flexibility (e.g., polymers). Here, we achieve a golden mean of these properties and obtain a lightweight, viscoelastic, high-K dielectric material by combining two nonpolar, brittle constituents, namely, sulfur (S) and selenium (Se). This S-Se alloy retains polymer-like mechanical flexibility along with a dielectric strength (40 kV/mm) and a high dielectric constant (K = 74 at 1 MHz) similar to those of estab

Low-dielectric-constant materials (k < 3.0) have the advantage of facilitating manufacture of higher performance integrated-circuit (IC) devices with minimal increases in chip size. The reduced capacitance given by these materials permits shrinkage of spacing between metal lines to below 0.25 μm and the ability to decrease the number of levels of metal in a device. The technologies being considered for low-k applications are chemical vapor deposition (CVD) or spin-on of polymeric materials. For both types of processes, there are methods and materials capable of giving k < 3.0 dielectric
