Abstract: GAA TSNWFET with 15 nm gate length and 4 nm radius nanowires is demonstrated and shows excellent short channel immunity. p-TSNWFET shows high driving current of 1.94 mA/?m while n-TSNWFET shows on-current on-current on-current of 1.44 mA/?m. Merits of TSNWFET and performance enhancement of p-TSNWFET are explored using 3-D and quantum simulation.

TL;DR: In this paper, the authors investigated the performance of nanowire transistor and found that 4 nm is the best point to maximize the volume inversion effect on gate all around nanowires MOSFET.
Abstract: Nanowire size (dNW) dependency of various electrical characteristics on gate all around twin silicon nanowire MOSFET (TSNWFET) is investigated to understand overall performance of nanowire transistor deeply. When dNW decreases, current drivability (Ion) normalized by circumference at the same VG-VTH improves and maximizes at dNW of 4 nm. And mobility is also estimated with capacitance and series resistance. All the experimental investigation shows that dNW of 4 nm is the best point to maximize the volume inversion effect on gate all around nanowire MOSFET.

TL;DR: In this paper, a sub-10 nm gate-all-around (GAA) CMOS silicon nanowire field effect transistors (SNWFET) was fabricated successfully for the first time with 13-nm-diameter silicon channel.
Abstract: In this paper, sub-10 nm gate-all-around (GAA) CMOS silicon nanowire field-effect transistors (SNWFET) on bulk Si substrate are fabricated successfully for the first time with 13-nm-diameter silicon nanowire channel. On-state currents of 1494/1054 muA/mum at off leakage currents of 102/6.44 nA/mum are obtained for N/PMOS, respectively. The impacts of nanowire diameter (DNW) and gate oxide thickness (TOX) as well S/D parasitic resistance (RSD) on performance are investigated in details.

TL;DR: In this paper, the authors demonstrate a double FinFET on bulk Si wafer, named multi-channel field effect transistor (McFET), for the high performance 80nm 144M SRAM.
Abstract: We demonstrate highly manufacturable double FinFET on bulk Si wafer, named multi-channel field effect transistor (McFET) for the high performance 80nm 144M SRAM. Twin fins are formed for each transistor using our newly developed simple process scheme. McFET with L/sub G/=80nm shows several excellent transistor characteristics, such as /spl sim/5 times higher drive current than planar MOSFET, ideal subthreshold swing of 60mV/dec, drain induced barrier lowering (DIBL) of 15mV/V without pocket implantation, and negligible body bias dependency, maintaining the same source/drain resistance as planar transistor due to the unique feature of McFET.

TL;DR: In this article, the oxide semiconductor film has at least a crystallized region in a channel region, which is defined as a region of interest (ROI) for a semiconductor device.
Abstract: An object is to provide a semiconductor device of which a manufacturing process is not complicated and by which cost can be suppressed, by forming a thin film transistor using an oxide semiconductor film typified by zinc oxide, and a manufacturing method thereof. For the semiconductor device, a gate electrode is formed over a substrate; a gate insulating film is formed covering the gate electrode; an oxide semiconductor film is formed over the gate insulating film; and a first conductive film and a second conductive film are formed over the oxide semiconductor film. The oxide semiconductor film has at least a crystallized region in a channel region.

TL;DR: In this article, the electron transport properties of group III-V compound semiconductors have been used for the development of the first nanometre-scale logic transistors, which is the first step towards the first IC transistors.
Abstract: For 50 years the exponential rise in the power of electronics has been fuelled by an increase in the density of silicon complementary metal-oxide-semiconductor (CMOS) transistors and improvements to their logic performance. But silicon transistor scaling is now reaching its limits, threatening to end the microelectronics revolution. Attention is turning to a family of materials that is well placed to address this problem: group III-V compound semiconductors. The outstanding electron transport properties of these materials might be central to the development of the first nanometre-scale logic transistors.

TL;DR: In the current generation of transistors, the transistor dimensions have shrunk to such an extent that the electrical characteristics of the device can be markedly degraded, making it unlikely that the exponential decrease in transistor size can continue.
Abstract: For more than four decades, transistors have been shrinking exponentially in size, and therefore the number of transistors in a single microelectronic chip has been increasing exponentially. Such an increase in packing density was made possible by continually shrinking the metal–oxide–semiconductor field-effect transistor (MOSFET). In the current generation of transistors, the transistor dimensions have shrunk to such an extent that the electrical characteristics of the device can be markedly degraded, making it unlikely that the exponential decrease in transistor size can continue. Recently, however, a new generation of MOSFETs, called multigate transistors, has emerged, and this multigate geometry will allow the continuing enhancement of computer performance into the next decade.

TL;DR: In this article, the authors summarized some of the essential aspects of silicon-nanowire growth and of their electrical properties, including the expansion of the base of epitaxially grown Si wires, a stability criterion regarding the surface tension of the catalyst droplet, and the consequences of the Gibbs-Thomson effect for the silicon wire growth velocity.
Abstract: This paper summarizes some of the essential aspects of silicon-nanowire growth and of their electrical properties. In the first part, a brief description of the different growth techniques is given, though the general focus of this work is on chemical vapor deposition of silicon nanowires. The advantages and disadvantages of the different catalyst materials for silicon-wire growth are discussed at length. Thereafter, in the second part, three thermodynamic aspects of silicon-wire growth via the vapor–liquid–solid mechanism are presented and discussed. These are the expansion of the base of epitaxially grown Si wires, a stability criterion regarding the surface tension of the catalyst droplet, and the consequences of the Gibbs–Thomson effect for the silicon wire growth velocity. The third part is dedicated to the electrical properties of silicon nanowires. First, different silicon nanowire doping techniques are discussed. Attention is then focused on the diameter dependence of dopant ionization and the influence of interface trap states on the charge carrier density in silicon nanowires. It is concluded by a section on charge carrier mobility and mobility measurements.
