Nonlinear optical resonance The drive to develop ultrasmall and ultrafast electronic devices using a single atomic layer of semiconductors, such as transition metal dichalcogenides, has received a significant boost. Researchers with Berkeley Lab have recorded the first observations of a strong nonlinear optical resonance along the edges of a single layer of molybdenum disulfide. The existence ... » read more

Litho beam startup A startup has developed a new beam technology for advanced lithography applications. The company, called Digibeam, has demonstrated the ability to shoot a particle beam through a slow wave RF structure to create a train of compressed beam packets for high-throughput lithography. “Synchronized with high-speed deflection, the core technology enables shot rates well into t... » read more

Beyond graphene Researchers at The University of Manchester have shown how they can control the properties of stacks of 2D materials, opening up the potential for new, previously-unimagined electronic devices. The isolation of graphene at the University in 2004 led to the discovery of many other 2D crystals and while graphene has an unrivaled set of superlatives, these crystals cover a larg... » read more

Making cheap diamonds Graphite and diamonds are two forms of the same element--carbon. In graphite, carbon atoms are arranged in planar sheets and the material is soft. On the other hand, diamonds consist of carbon atoms that are bonded in all directions, making these structures extremely hard. [caption id="attachment_11311" align="alignleft" width="150"] This illustration shows four layers... » read more

How Much Will That Chip Cost?
By Ed Sperling - 27 Mar, 2014 - Comments: 1

From the most advanced process nodes to the trailing edge of design there is talk about the skyrocketing cost of developing increasingly complex SoCs. At 16/14nm it’s a combination of multi-patterning, multiple power domains and factoring in physical and proximity effects. At older nodes, it’s the shift to more sophisticated versions of the processes and new tools to work within those proce... » read more

Why Would IBM Sell Its Semi Group?
By Ed Sperling - 20 Feb, 2014 - Comments: 1

Rumors are always just rumors until proven otherwise in business, but in the case of IBM’s semiconductor business, hints about the sale of its semiconductor business are particularly noteworthy. Much has changed since the days when IBM—as International Business Machines—went head-to-head with AT&T’s quasi-public Bell Labs and Xerox’s Palo Alto Research Center (PARC). The breakup of... » read more

Speeding Access To Information Big data today is usually stored on multiple hard disks on a number of machines across an Ethernet network, but this storage architecture considerably increases the time it takes to access the information. Researchers at MIT have developed a storage system for big-data analytics they claim can dramatically reduce the time it takes to access information. The sy... » read more

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?
By Mark LaPedus - 24 Jan, 2014 - Comments: 3

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
