For several decades, the development of metal-oxide-semiconductor field-effect transistors have made available to us better circuit time and efficiency per function with each successive generation of CMOS technology. However, basic product and manufacturing technology limitations will make continuing transistor scaling difficult in the sub-32 nm zone. Field impact transistors with fins were developed. offered as a viable solution to the scalability difficulties. Fin field effect transistors can be made in the same way as regular CMOS transistors, allowing for a quick transition to production.

In recent years, scaling of semiconductor device has progressed, leading to the development of advanced semiconductor devices with code names of below 10-nm. Various new materials and technologies have been introduced to accompany the miniaturization of semiconductor devices. First, the resistivity of aluminum became higher due to miniaturization, and aluminum was replaced by copper as the wiring metal. Then, to increase the gate capacitance of MOS field-effect transistors, the thickness of the gate insulating film (SiO2) was reduced to the limit, and as a result, gate leakage current could no

Advances in the theory of semiconductors in the 1930s in addition to the purification of germanium and silicon crystals in the 1940s enabled the point-contact junction transistor in 1947 and initiated the era of semiconductor electronics. Gordon Moore postulated 18 years later that the number of components in an integrated circuit would double every 1 to 2 years with associated reductions in cost per transistor.

Pivotal in the design of circuits is the ability to efficiently translate available transistor gain to high gain per stage. Remarkably, for 35-nm InP HEMT transistors, the efficiency of this translation remains high even up to ~0.5 THz. The ever shrinking wavelength correlated with higher frequencies necessitates a scaling of not only the device layout, but also of the passive elements and wafer thickness. Furthermore, to avoid distributed effects, the length of transistor gate fingers must be reduced.

Feature scaling in advanced CMOS technology has been slowing down starting at 10 nm node and is expected to stop completely in the next few years. Nevertheless, transistor density scaling is continuing at a Moore’s law pace, driven by DTCO and 3D IC. Transistor dimensions and minimum metal pitch are expected to be massaged down only by 10% to 20% during the next decade. However, both the transistor and the interconnect will continue to evolve and improve both in performance and in variability.

After more than five decades, Moore’s Law for transistors is approaching the end of the international technology roadmap of semiconductors (ITRS). The fate of complementary metal oxide semiconductor (CMOS) architecture has become increasingly unknown. In this era, 3D transistors in the form of gate-all-around (GAA) transistors are being considered as an excellent solution to scaling down beyond the 5 nm technology node, which solves the difficulties of carrier transport in the channel region which are mainly rooted in short channel effects (SCEs). In parallel to Moore, during the last two deca

To enable CMOS transistor density scaling following Moore’s Law, device architectures transitioned in the past decade from the historical 2D planar transistor to FINFET. The next innovation touted for the 3nm node is a 3D stacked gate-all-around architecture in combination with a backside power delivery network. For further scaling, stacking nmos and pmos, the so-called complementary-FET (CFET) design, is envisaged to happen in 2030. The shrinking device dimensions of the interconnects require also new metallization schemes to tackle the RC challenge, such as Cu replacements materials in a dir

Transistor scaling has become increasingly difficult in the dynamic random access memory (DRAM). However, vertical devices will be good candidates for 4F2 DRAM cell transistors (F = pitch/2). Most vertical devices are facing some technical challenges. For example, the gate length cannot be precisely controlled, and the gate and the source/drain of the device cannot be aligned. Recrystallization-based vertical C-shaped-channel nanosheet field-effect transistors (RC-VCNFETs) were fabricated. The critical process modules of the RC-VCNFETs were developed as well.

A novel vertical dual surrounding gate transistor with embedded oxide layer is proposed for capacitorless single transistor DRAM (1T DRAM). The embedded oxide layer is innovatively used to improve the retention time by reducing the recombination rate of stored holes and sensing electrons. Based on TCAD simulations, the new structure is predicted to not only have the characteristics of fast access, random read and integration of 4F2 cell, but also to realize good retention and deep scaling. At the same time, the new structure has the potential of scaling compared with the conventional capacitor

As the semiconductor devices of integrated circuits approach the physical limitations of scaling, alternative transistor and memory designs are needed to achieve improvements in speed, density, and power consumption. We report on a transistor that uses an embedded tunneling field-effect transistor for charging and discharging the semi-floating gate. This transistor operates at low voltages (≤2.0 volts), with a large threshold voltage window of 3.1 volts, and can achieve ultra–high-speed writing operations (on time scales of ~1 nanosecond).

In this paper, we present an extensive analysis of the performance degradation in MOSFET based circuits. The physical effects that we consider are the random dopant fluctuation (RDF), the oxide thickness fluctuation (OTF) and the Hot-carrier-Instability (HCI). The work that we propose is based on two main key points: First, the performance degradation is studied considering BULK, Silicon-On-Insulator (SOI) and Double Gate (DG) MOSFET technologies. The analysis considers technology nodes from 45nm to 11nm. For the HCI effect we consider also the time-dependent evolution of the parameters of the

The hot-carrier injection is observed increasingly to degrade the I–V characteristics with the scaling of MOS transistors. For the lightly doped drain MOS transistor the injection of the hot-carriers, caused by the high electric field in the MOS structure, is localized in the LDD region. The modeling of the drain current in relation to defects due to the hot-carrier injection allows us to investigate the I–V characteristics and the transconductance of devices. Consequently, we can know the amount of the device degradation caused by these defects in order to find technological solutions to opti
