Chapter 1: The evolution of silicon-based complementary metal-oxide semiconductor (CMOS) technology has been essential in shaping modern semiconductor electronics. In this evolution, the steady scaling of transistors has contributed a lot, and these steady developments of transistors enabled the recent high-performance semiconductor chips. In this book chapter, we are going to explore the historical scaling advancements in CMOS technology, highlighting the challenges faced in the past and present. Past challenges encompassed issues such as short-channel effects and leakage currents, while current challenges revolve around power dissipation and quantum effects at nanoscale dimensions. Looking forward, the chapter also discusses potential future innovations including novel materials, device architectures, and computing paradigms. By addressing these challenges and embracing new technologies, Si-based CMOS is poised to continue its transformative journey in the semiconductor industry. Even though there are still a couple of issues to be overcome, it seems like the CMOS technology is able to keep on improving, with the help of material development and fabrication-equipment development. This chapter has been written to understand the basic principles of semiconductors and the demands for improving scaling and subthreshold swing, which are essential for designing FeFET.

Chapter 2: Ferroelectric polymers in organic field-effect transistors (OFETs) have garnered significant attention as they offer cost-effective means and simplified manufacturing processes based on solution process-ability and flexible memory modules. They can be fabricated by various solution processing techniques such as spin coating, Langmuir-Blodgett, ink-jet printing, and roll-to-roll printing. Organic ferroelectric field-effect transistors (FeFETs) can be used in large electronic applications: flexible displays, sensors, radio frequency identification (RFID) tags, etc. An additional benefit of PVDF copolymers like poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] is their ability to rapidly crystallize into the β phase. The β phase shows the maximum dipole moment within various reported polar phases. Ferroelectric polymer material–based devices have shown good memory functionalities which can have great significance for various applications. Particularly, OFET having ferroelectric polymer as a gate dielectric layer has attracted huge interest because of their large potentiality aimed at the growth of nonvolatile memory devices at low cost. This work highlights the diverse applications of FeFETs in advancing nonvolatile memory, artificial synapses, and wearable technologies, leveraging ferroelectric polymers.

Chapter 3: Advancement in next-generation technologies demands multifunctional devices with ultrafast speed, low cost, and smaller size. Therefore, immense efforts are being made to understand the complex and cooperative behavior of current, charge, electric dipole moments, and/or spin degrees of freedom of materials. For example, ferroelectrics (a non-centrosymmetric material with switchable spontaneous polarization) near or below the size of 3.2 nm are appealing to explore their potential application for next-generation devices. Ferroelectric materials are generally used as a tuneable capacitor and data storage devices in various electronic systems such as mobiles, computers, space centers, and satellites. They can also be utilized as crucial electronic components such as a phase shifter, electrocaloric effect-based cooler, memory, and energy harvester in satellites and/or space flight-based advance devices. To improve the functionality of these materials further, extensive studies are required. We briefly present here the basic concept of ferroelectricity, necessities, facile and advanced synthesis techniques, and potential applications of ferroelectric materials in novel devices.

Chapter 4: This chapter introduces a hetero-buried oxide (HBOX)–ferroelectric tunnel FET. Numerous electrical parameters are tuned concerning the silicon and BOX layer thickness adjustment, including ON/OFF-state currents and ION/IOFF ratio. A negative capacitance–based ferroelectric gate stack is also introduced for obtaining the steep subthreshold slope (SS). To ensure compatibility with the typical FET production approach, a ferroelectric (Fe) layer comprised of silicon-doped hafnium oxide is employed at the bottom of the gate. The Fe layer thickness is carefully optimized to improve Analog and DC parameters. A doped pocket (n+) has been imparted within the source in conjunction with the gate overlapping and drain underlapping. In addition to the design features, a pocket improves the electric field around the tunnel junction, making it more likely for the carriers to tunnel toward the channel. The heteroburied oxide is integrated into the silicon-on-insulator material. A high k-BOX remains at the source and a low k-BOX is exploited at the drain sides to minimize the ambipolar properties of the TFET and increase the ON-state current. The proposed structure’s characteristics have been optimized to accommodate changes in its physical dimensions. This arrangement provides a 38.5 mV/dec subthreshold slope and an ION/IOFF ratio of around 109. The Fe HBOX TFET is known to operate at an impressive speed, depending on the capacitances recovered from it. It is suitable for analog/RF applications as it exhibits superior transconductance and a reduced amount of output conductance. The steep subthreshold slope makes it ideal for low-power-demanding applications. The proposed ferroelectric TFET device evaluations are performed with the Sentaurus TCAD 2D software.

Chapter 5: A thorough analysis of ferroelectric materials in cutting-edge nanoelectronics devices is presented here. Ferroelectric material–based FETs describe how mitigating the problem arises in conventional CMOS. A ferroelectric polarization field is injected into a field-effect transistor (FET) to control semiconductor carriers, resulting in a ferroelectric field-effect transistor (FeFET). This article compares several ferroelectric materials’ characteristics, such as HfO2, PZT, and other 2D materials, and shows how ferroelectricity varies with temperature. After outlining the distinct electrical and physical characteristics of ferroelectric materials, we concentrate on different structures of field-effect transistors with ferroelectric materials based on 2D and 3D structures. FeFET’s different architectures, such as MFS and MFIS, and applications based on these structures are also given. The various FeFET structures are compared to each other in terms of performances and limitations to the real world. The other structures of field-effect transistors are proposed based on ferroelectric materials for various applications such as memory and sensors. To pique the attention of scientists interested in the continued development of this rapidly developing field of study, this article thoroughly analyzes the current and upcoming challenges in ferroelectric-based nanoelectronics. FeFETs are appealing for cutting-edge electrical and optoelectronic applications, such as developing memory, artificial neural networks, high-performance photodetectors, and intelligent sensors due to their ferroelectric and semiconductor flexible interaction. In this review, we also covered the potential applications of FeFET in the future for better device operation and which ferroelectric materials have the best FeFET structure and can retain ferroelectricity up to 1-nm technology.
