Nanotech tools a $700M market

"Analysts have compared instruments for nanotechnology to shovels for the gold rush," said Nathan Tinker, co-founder and executive vice president of the NanoBusiness Alliance in New York City.The atomic-force microscope "is the granddaddy of nanotechnology tools."

Invented in 1986 by IBM physicists Gerd Binnig and Christoph Gerber, with Stanford University electrical engineer Calvin Quate, the atomic-force microscope, or AFM, runs sharp probes up and down surfaces to scan with three-dimensional atomic-level detail, much as a blind person uses his or her fingers to read bumps on a page of Braille.Scientists also can use AFM probes as fingers to control features on the nanoscale.

AFMs and similar devices, such as near-field optical-scanning microscopes and electrostatic-force microscopes, are now being developed "from purely research tools to work in large-scale production processes," Tinker said."That's very exciting to me.With a research tool, you can make really cool items once or twice, but not at scales you need for industrial needs."

A growing market within nanotechnology tools lies in accessories to existing AFMs and other workhorse machines."These are probes or tips that you stick on the end of a microscope that can do whatever you want them to," said Tinker, who drafted a report on nanotech tools for analyst firm Business Communications Company in Norwalk, Conn."There are a lot of smart entrepreneurs and scientists who are developing more and more advanced accessories to add onto standardized scopes as you get more and more specialized applications."For instance, he continued, "you see classic AFMs and other scanning microscopes being adapted and utilized for biological processes, for constructing drug molecules and even testing diagnostics and so forth, that are able to get down and very, very quickly and accurately assess a molecule or small portion of molecules within a blood sample to diagnose any number of diseases."

Instruments traditionally used only on the nanoscale level for semiconductor processes also will find use outside the semiconductor industry, said Lawrence Gasman, principal analyst for NanoMarkets, an industry research firm in Sterling, Va.

"As an example of these types of crossovers, when you talk about a company like NanoInk (in Chicago), which developed dip-pen lithography, people initially thought of it for a semiconductor industry mode of production," Gasman said, "but one of the things they've actually had the most success with is creating encrypted IDs on drugs."

The largest market for nanotech tools outside the semiconductor industry so far is still research and development."There are still not a lot of industrial end users out there using nanotools specifically to create and produce nanoproducts," Tinker said.

"There needs to be a concerted development effort among nanotechnology companies to talk with toolmakers to develop these tools to the point where they have legs in industrial markets," he added."We have to figure out what we need to do, a roadmap to get to those points, and various stoplights and ways around them, and we don't see that at all.There needs to be an organization that brings those disparate constituencies together and get them talking about the industrial side of the process."

IBM Develops Computational Scaling Solution for Next Generation '22nm' Semiconductors
In response to ever increasing demands for smaller, more powerful and energy-efficient devices for cloud computing and high-performance servers, IBM today announced the semiconductor industry's first computationally based process for production of next generation 22nm semiconductors. Known as Computational Scaling (CS) -- a process that enables the production of complex, powerful and energy-efficient semiconductors at 22nms and beyond -- this new initiative will feature support from several of IBM's key partners initially including Mentor Graphics and Toppan Printing.
IMEC reports major progress in EUV
IMEC reports functional 0.186µm2 32nm SRAM cells made with FinFETs from which the contact layer was successfully printed using ASML’s full field extreme ultraviolet (EUV) Alpha Demo Tool (ADT). Applied Materials, using its most advanced deposition systems, was key to fabricating the ultra-small circuit structures. IMEC also completed the integration and site acceptance test of the EUV ADT in its 300mm clean room.
Researchers Create Enhanced Light Sources For Lithography
A breakthrough discovery at UC San Diego may help aid the semiconductor industry’s quest to squeeze more information on chips to accelerate the performance of electronic devices. So far, the semiconductor industry has been successful in its consistent efforts to reduce feature size on a chip. Smaller features mean denser packing of transistors, which leads to more powerful computers, more memory, and hopefully lower costs.
Exposing the Sensitivity of Extreme Ultraviolet Photoresists
Researchers at the National Institute of Standards and Technology (NIST) have confirmed that the photoresists used in next-generation semiconductor manufacturing processes now under development are twice as sensitive as previously believed. This finding, announced at a workshop last month,* has attracted considerable interest because of its implications for future manufacturing. If the photoresists are twice as sensitive as previously thought, then they are close to having the sensitivity required for high volume manufacturing, but the flip side is that the extreme ultraviolet optical systems in the demonstration tools currently being used are only about half as effective as believed.

Researchers develop better X-ray nanomirrors
A new way of bending X-ray beams developed by MIT researchers could lead to greatly improved space telescopes, as well as new tools for biology and for the manufacture of semiconductor chips.
Unique locks on microchips could reduce hardware piracy
Hardware piracy, or making knock-off microchips based on stolen blueprints, is a burgeoning problem in the electronics industry.
AMD, Partners Produce Test Chip Using EUV Lithography
AMD, working together with its research partner, IBM, announced it has produced a working test chip utilizing Extreme Ultra-Violet (EUV) lithography for the critical first layer of metal connections across the entire chip.
EPIC: Building the Perfect Chip
Three years ago a team from Bell Labs took on a very daunting challenge – put an optical networking system on a commercially manufactured silicon chip, load it with a smorgasbord of sophisticated opto-electronic devices in a combination that’s never been done before, and make it easy to mass produce.
