Abstract:
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

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:
As the scaling of complementary metal-oxide-semiconductor (CMOS) transistors proceeds, the thickness of the SiO2 gate dielectrics shrinks rapidly and results in higher gate leakage currents. High k dielectric materials are acknowledged to be the possible solutions to this challenge, as their higher k values (e.g., 15–50) raise the physical thickness of the dielectrics that provide similar equivalent thickness of a thinner SiO2 film. In order for the high k materials to be applicable in CMOS devices, there should exist deposition technologies that can deposit highly uniform films over Si wafers

Abstract:
With continual scaling of ICs, the thickness of gate oxide becomes thinner and thinner which affects the reliability of semiconductor device greatly. The mechanism of time-dependent dielectric breakdown (TDDB) was analyzed. Six mathematical models of TDDB which were divided according to the position of defects and the physical property of charged particles were discussed. Then the dielectric breakdown characteristic of high k dielectrics and the relationships between the breakdown electric field, field acceleration parameter and dielectric constant were analyzed in detail. Finally, the relatio

Abstract:
Historically SiO2 was the main driver as the transistor gate dielectric in CMOS technology. Once the thickness of SiO2 reached the onset of direct tunneling region (<1.5 nm) HfO2 -based high-k insulators were introduced to suppress the direct-tunneling leakage current. ECS started a symposium on Physics and Technology of High-k Gate Dielectrics in 2002 describing the evolution of dielectric science in nanoelectronics. In recent years transistor has transformed from a planar device to a three-dimensional device to a gate all around device. The electrical performance in these devices depends

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

Abstract:
Relations between the electronic properties of high-k materials and electrical characteristics of high-k transistor are discussed. It is pointed out that the intrinsic limitations of these materials from the standpoint of gate dielectric applications are related to the presence of d-electrons, which facilitate high values of the dielectric constant. It is shown that the presence of structural defects responsible for electron trapping and fixed charges, and the dielectrics' tendency for crystallization and phase separation induce threshold voltage instability and mobility degradation in high-k

The paper reviews recent work in the area of high-k dielectrics for application as the gate oxide in advanced MOSFETs. Following a review of relevant dielectric physics, we discuss challenges and issues relating to characterization of the dielectrics, which are compounded by electron trapping phenomena in the microsecond regime. Nearly all practical methods of preparation result in a thin interfacial layer generally of the form SiOx or a mixed oxide between Si and the high-k so that the extraction of the dielectric constant is complicated and values must be qualified by error analysis.

A new high-k dielectric material, i.e., zirconium-doped tantalum oxide (Zr-doped TaOx), in the form of a sputter-deposited thin film with a thickness range of 5-100 nm, has been studied. Important applications of this new dielectric material include the gate dielectric layer for the next generation metal-oxide-semiconductor field effect transistor (MOSFET). Due to the aggressive device scaling in ultra-large-scale integrated circuitry (ULSI), the ultra-thin conventional gate oxide (SiO2) is unacceptable for many practical reasons.

As the device feature size shrinks, films of silicon oxide (SiO₂) will become unsuitable for MOSFET gate dielectric applications and have to be replaced by thicker films of a high-k dielectric material. Among the high-k materials, hafnium oxide (HfO₂) and zirconium oxide (ZrO₂) are the most promising candidates. Molecular contamination can affect the quality of the new gate dielectric films in a manner similar to ultrathin SiO2 films. Therefore, characterization of contaminant adsorption behavior of these high-k films should assist in deciding their potential for successful integration in sili
