What’s For Dinner?
By Katherine Derbyshire - 12 Feb, 2019 - Comments: 2

Robots, as currently implemented, don’t do well in uncontrolled environments. In factories and warehouses, they are fenced off by yellow safety tape, doing highly repetitive and predictable tasks. When deployed to monitor parks and malls, they are easily thwarted by malicious humans and even unexpected landscape features. Yet robots able to assist elderly and disabled people will be genuin... » read more

In-Memory Computing Challenges Come Into Focus
By Katherine Derbyshire - 06 Feb, 2019 - Comments: 6

For the last several decades, gains in computing performance have come by processing larger volumes of data more quickly and with superior precision. Memory and storage space are measured in gigabytes and terabytes now, not kilobytes and megabytes. Processors operate on 64-bit rather than 8-bit chunks of data. And yet the semiconductor industry’s ability to create and collect high quality ... » read more

Quantum Issues And Progress
By Katherine Derbyshire - 07 Jan, 2019 - Comments: 3

Quantum computing is showing significant promise, and research is beginning to move from the earliest stages to a deeper understanding of what works best commercially and why. On paper, quantum computing algorithms are potentially revolutionary. They suggest a way to solve some problems more quickly and more accurately than conventional computers ever could. But out in the real world of prac... » read more

Interest Grows In Ferroelectric Devices
By Katherine Derbyshire - 27 Dec, 2018 - Comments: 0

Ferroelectric FETs and memories are beginning to show promise as researchers begin developing and testing next-generation transistors. One measure of the efficiency of a transistor is the subthreshold swing, which is the change in gate voltage needed to increase the drain current by one order of magnitude. Measured in units of millivolts per decade, in conventional MOSFETs it is limited to k... » read more

What’s A Mott FET?
By Katherine Derbyshire - 17 Dec, 2018 - Comments: 0

The unique physics of two-dimensional semiconductors offers the potential for new kinds of switches that could extend the usefulness of conventional MOSFETs into a variety of new areas. A MOSFET applies a voltage to one side of the gate capacitor. The resulting electric field in the channel shifts the band structure and facilitates or impedes the flow of carriers. So as devices shrink, the g... » read more

Can Graphene Be Mass Manufactured?
By Katherine Derbyshire - 18 Oct, 2018 - Comments: 3

Since the isolation of graphene in 2004, the high mobility and unique transport properties of 2-dimensional semiconductors have tantalized physicists and materials scientists. Their in-plane carrier transport and lack of dangling bonds potentially can minimize line/edge scattering and other effects of extreme scaling. While 2-D materials cannot compete with silicon at current device dime... » read more

Collaboration And Advanced Substrates
By Katherine Derbyshire - 08 Oct, 2018 - Comments: 0

Discussions of semiconductor manufacturing tend to focus on CMOS logic and memory devices, sometimes to the exclusion of everything else. Discussions of silicon-on-insulator wafer markets focus on the needs of high performance logic. Lithography analysts emphasize high density memories. It’s easy to forget that real systems contain other devices, too. A modern smartphone probably supports ... » read more

Making Organic Semiconductors Plastic
By Katherine Derbyshire - 12 Jul, 2018 - Comments: 0

Plastic. The very word implies deformability, the ability to bend and flex without damage in response to stress. In applications from biomedical sensors to solar cells, the potential advantages of organic semiconductors depend almost entirely on their deformability—are they flexible enough for inexpensive roll-to-roll processing? Able to tolerate flexion in use? Able to do without the bulky a... » read more

The Growing Materials Challenge
By Katherine Derbyshire - 11 Jun, 2018 - Comments: 0

By Katherine Derbyshire & Ed Sperling Materials have emerged as a growing challenge across the semiconductor supply chain, as chips continue to scale, or as they are utilized in new devices such as sensors for AI or machine learning systems. Engineered materials are no longer optional at advanced nodes. They are now a requirement, and the amount of new material content in chips contin... » read more

Integrating Memristors For Neuromorphic Computing
By Katherine Derbyshire - 16 May, 2018 - Comments: 1

Much of the current research on neuromorphic computing focuses on the use of non-volatile memory arrays as a compute-in-memory component for artificial neural networks (ANNs). By using Ohm’s Law to apply stored weights to incoming signals, and Kirchoff’s Laws to sum up the results, memristor arrays can accelerate the many multiply-accumulate steps in ANN algorithms. ANNs are being dep... » read more
