Fundamentals of III-V Semiconductor MOSFETs presents the fundamentals and current status of research of compound semiconductor metal-oxide-semiconductor field-effect transistors (MOSFETs) that are envisioned as a future replacement of silicon in digital circuits. The material covered begins with a review of specific properties of III-V semiconductors and available technologies making them attractive to MOSFET technology, such as band-engineered heterostructures, effect of strain, nanoscale control during epitaxial growth. Due to the lack of thermodynamically stable native oxides on III-V's (such as SiO2 on Si), high-k oxides are the natural choice of dielectrics for III-V MOSFETs. The key challenge of the III-V MOSFET technology is a high-quality, thermodynamically stable gate dielectric that passivates the interface states, similar to SiO2 on Si. Several chapters give a detailed description of materials science and electronic behavior of various dielectrics and related interfaces, as well as physics of fabricated devices and MOSFET fabrication technologies. Topics also include recent progress and understanding of various materials systems; specific issues for electrical measurement of gate stacks and FETs with low and wide bandgap channels and high interface trap density; possible paths of integration of different semiconductor materials on Si platform.

In 1959, Atalla and Kahng at Bell Labs produced the first successful field-effect transistor (FET), which had been long anticipated by other researchers by overcoming the "surface states" that blocked electric fields from penetrating into the semiconductor material. Very quickly, they became the fundamental basis of digital electronic circuits. Up to this point, there are more than 20 different types of field-effect transistors that are incorporated in various applications found in everyday's life. Based on this fact, this book was designed to overview some of the concepts regarding FETs that are currently used as well as some concepts that are still being developed.

The path of down-scaling traditional MOSFET is reaching its technological, economic and, most importantly, fundamental physical limits. Before the dead-end of the roadmap, it is imperative to conduct a broad research to find alternative materials and new architectures to the current technology for the MOSFET devices. Beyond silicon electronic materials like group III-V heterostructure, ferroelectric material, carbon nanotubes (CNTs), and other nanowire-based designs are in development to become the core technology for non-classical CMOS structures. Field effect transistors (FETs) in general have made unprecedented progress in the last few decades by down-scaling device dimensions and power supply level leading to extremely high numbers of devices in a single chip. High density integrated circuits are now facing major challenges related to power management and heat dissipation due to excessive leakage, mainly due to subthreshold conduction. Over the years, planar MOSFET dimensional reduction was the only process followed by the semiconductor industry to improve device performance and to reduce the power supply. Further scaling increases short-channel-effect (SCE), and off-state current makes it difficult for the industry to follow the well-known Moore’s Law with bulk devices. Therefore, scaling planar MOSFET is no longer considered as a feasible solution to extend this law. The down-scaling of metal-oxide-semiconductor field effect transistors (MOSFETs) leads to severe short-channel-effects and power leakage at large-scale integrated circuits (LSIs). The device, which is governed by the thermionic emission of the carriers injected from the source to the channel region, has set a limitation of the subthreshold swing (S) of 60 mV/decade at room temperature. Devices with ‘S’ below this limit is highly desirable to reduce the power consumption and maintaining a high Ion/Ioff current ratio. Therefore, the future of semiconductor industry hangs on new architectures, new materials or even new physics to govern the flow of carriers in new switches. As the subthreshold swing is increasing at every technology node, new structures using SOI, multi-gate, nanowire approach, and new channel materials such as III–V semiconductor have not satisfied the targeted values of subthreshold swing. Moreover, the ultra-low-power (ULP) design required a subthreshold slope lower than the thermionic emission limit of 60 mV/decade. This value was unbreakable by the new structure (SOI FinFET). On the other hand, most of the preview proposals show the ability to go beyond this limit. However, those pre-mentioned schemes have publicized very complicated physics, design difficulties, and process non-compatibility. The objective of this research is to discuss various emerging nano-devices proposed for sub-60 mV/decade designs and their possibilities to replace the silicon devices as the core technology in the future integrated circuit. This dissertation also proposes a novel design that exploits the concept of negative capacitance. The new field-effect-transistor (FET) based on ferroelectric insulator named Silicon-On-Ferroelectric Insulator Field effect-transistor (SOFFET). This proposal is a promising methodology for future ultra low-power applications because it demonstrates the ability to replace the silicon-bulk based MOSFET, and offers a subthreshold swing significantly lower than 60 mV/decade and reduced threshold voltage to form a conducting channel. The proposed SOFFET design, which utilizes the negative capacitance of a ferroelectric insulator in the body-stack, is completely different from the FeFET and NCFET designs. In addition to having the NC effect, the proposed device will have all the advantages of an SOI device. Body-stack that we are intending in this research has many advantages over the gate-stack. First, it is more compatible with the existing processes. Second, the gate and the working area of the proposed SOFFET is like the planar MOSFET. Third, the complexity and ferroelectric material interferences are shifted to the body of the device from the gate and the working area. The proposed structure offers better scalability and superior constructability because of the high-dielectric buried insulator. Here we are providing a very simplified model for the structure. Silicon-on-ferroelectric leads to several advantages including low off-state current and shift in the threshold voltage with the decrease of the ferroelectric material thickness. Moreover, having an insulator in the body of the device increases the controllability over the channel, which leads to the reduction in the short-channel-effect (SCE). The proposed SOFFET offers low value of subthreshold swing (S) leading to better performance in the on-state. The off-state current is directly related to S. So, the off-state current is also minimum in the proposed structure.
