Manufacturing Bits: Feb. 4


Secrets of mass variation The General Conference on Weights and Measures will soon approve a plan to redefine the kilogram and other measurement units. The new definition for the kilogram will be based on the fixed numerical values of Planck’s constant (h). Supposedly, the new definition will solve the current problem. The kilogram is the only SI unit that is still described as an artif... » read more

What’s After CMOS?


Chipmakers continue to scale the CMOS transistor to finer geometries, but the question is for how much longer. The current thinking is that the CMOS transistor could scale at least to the 3nm node in the 2021 timeframe. And then, CMOS could run out of gas, prompting the need for a new switch technology. So what’s after the CMOS-based transistor? Carbon nanotubes and graphene get the most a... » read more

Executive Viewpoint: Qualcomm On Process Technology


Semiconductor Engineering sat down to discuss current and future process technology challenges with Geoffrey Yeap, vice president of technology at Qualcomm. SE: You have pointed out there is a fundamental shift taking place at the 28nm logic node. This is the first node in which mobile chips have been ramped up first within the foundries, ahead of computing-based ICs. Many believe that 28nm ... » read more

MoS2 FETs Two-dimensional materials are gaining steam in the R&D labs. The 2D materials include graphene, boron nitride (BN) and the transition-metal dichalcogenides (TMDs). One TMD, molybdenum diselenide (MoS2), is an attractive material for use in future field-effect transistors (FETs). MoS2 has several properties, including a non-zero band gap, atomic scale thickness and pristine int... » read more

Animal robots invade London The London Science Museum will premiere U-CAT, an underwater robot turtle designed to penetrate shipwrecks. In the exhibit, the museum will also showcase several robots that resemble an eel, bat, cheetah cub, tumbleweed, tuna, salamander and other creatures. Meanwhile, built by the Centre for Biorobotics at Tallinn University of Technology, U-CAT’s locomotio... » read more

System Bits: Nov. 5


Silicon Photonics And Graphene The industry is looking towards silicon photonics that will increase the rate at which electronic systems can communicate with each other and reduce power consumption. Researchers at MIT, Columbia University and IBM’s T. J. Watson Research Center are already a few steps beyond the traditional attempts to build optical components using materials such as Gallium ... » read more

System Bits: Oct. 22


Untangled nanotubes Carbon nanotubes are lightweight, strong and conduct electricity, which make them ideal components in new electronics devices, such as tablet computers and touchscreen phones, but cannot be used without being separated out from their natural tangled state. Researchers from Imperial College London have developed a way to unravel and apply carbon nanotubes in the laboratory a... » read more

Power/Performance Bits: Oct. 8


How light interacts with gold nanostructures With the potential to possibly increase the efficiency of solar cells and photo detectors, University of Manchester researchers have discovered that graphene can be used to investigate how light interacts with nano-antennas. The team, which also included researchers from Freie Universität Berlin and Imperial College London, have shown that graph... » read more
