Chips’ future cast

June 20, 2002
Image A shows a quartz template used to press ultrasmall patterns into silicon. Image B shows the pattern as it appears in silicon.

A new laser-stamping technique could produce computer chips with 100 times more transistors on a chip, according to Stephen Chou of Princeton University.

The research could lead to patterns imprinted with features only 10 nanometers wide onto a silicon wafer, compared to the lower limit of about 130 nanometers wide with photolithography.

The technique is derived from a similar method used to print compact discs.… read more

Chips Coming to a Brain Near You

October 25, 2004

Professor Theodore W. Berger, director of the Center for Neural Engineering at the University of Southern California, is creating a silicon chip implant that mimics the hippocampus. It could replace its biological counterpart, enabling people who suffer from memory disorders to regain the ability to store new memories.

The chip simulates the processing of biological neurons in the slice of rat hippocampus: accepting electrical impulses, processing them using mathematical… read more

Chips as mini Internet

The data-routing techniques that undergird the Internet could increase the efficiency of multicore computer chips while lowering their power requirements, MIT computer scientists suggest.

Li-Shiuan Peh, an associate professor of electrical engineering and computer science at MIT’s Department of Electrical Engineering and Computer Science, wants cores to communicate the same way computers hooked to the Internet do: by bundling the information they… read more

Chip-in-a-pill may be approved in 2012

November 10, 2010

(Proteus Biomedical)

Swiss pharmaceutical company Novartis AG is developing a pill containing an embedded microchip, which it hopes to submit for regulatory approval in Europe within 18 months.

The chip is activated by stomach acid and transmits information to a patch attached to the patient’s skin, which then sends it on to a doctor via the Internet or a smartphone.

The first application of the chip-in-a-pill — or as it… read more

Chip-cooling Technology Achieves ‘Dramatic’ 1,000-watt Capacity

July 7, 2008

Purdue University researchers have developed a technology that uses “microjets” to deposit liquid into tiny channels and remove five times more heat (1,000 watts per square centimeter) than other experimental high-performance chip-cooling methods for computers and electronics.

Chip roadmap to get wireless upgrade

July 18, 2003

Semiconductor industry representatives are considering the addition of wireless communications technologies to the 2003 International Technology Roadmap for Semiconductors.

The extension recognizes the need to address the post-CMOS era, when CMOS runs out of gas in the 2010 to 2015 time frame.

Chip rewires itself on the fly

April 27, 2004

The first processor that can add new instructions while operating was announced by startup Stretch.

The chip combines an existing RISC (reduced instruction set computing) architecture with a large reconfigurable area of programmable logic. Developer-generated software automatically spots areas in a program that require intensive computation and creates new instructions for the processor to handle those tasks.

Typical tasks, such as performing encryption or digital video processing on… read more

Chip ramps up neuron-to-computer communicati

March 28, 2006

A specialised microchip that could communicate with thousands of individual brain cells has been developed by European scientists.

The device will help researchers examine the workings of interconnected brain cells, and might one day enable them to develop computers that use live neurons for memory.

It is capable of receiving signals from more than 16,000 mammalian brain cells in vitro, and sending messages back to several hundred cells.

Chip protects single atoms

July 2, 2004

Researchers from the Max Planck Institute for Quantum Physics and Ludwig Maximilians University have found a way to closely control the quantum states of single atoms trapped in a microchip.

The method is a step toward building devices that depend on traits of single atoms, like miniature atomic clocks that are an order of magnitude more accurate than those that exist today, and quantum computers.

The researchers’ chip… read more

Chip miniaturization extended by strontium titanate

January 2, 2004

Researchers have found a way to use strontium titanate applied to a silicon wafer to extend the miniaturization and speed of transistors.

Silicon currently limits chip miniaturization because at a few atomic layers it loses its insulating property. Applying a strontium titanate layer overcomes that limit, according to simulations by Austrian researchers.

Chip Maker Develops Denser Storage Method

May 9, 2005

Matrix Semiconductor is expected to announce on Tuesday that its approach – storing data in an array of circuits stacked in four levels – had yielded one-gigabit chips that are 10 percent smaller than its previous version and have twice the memory of the original 512-megabit chips.

Chip integrates chemical, logic functions

chemical_chip

An integrated chemical chip that could control and regulate the signal paths of cells in the human body has been developed by Klas Tybrandt, a doctoral student in Organic Electronics at Linköping University, Sweden.

It creates the basis for an entirely new circuit technology based on ions and molecules instead of electrons and holes.

The Organic Electronics research group at Linköping University previously developed ion transistors for… read more

Chip Industry Sets a Plan for Life After Silicon

December 29, 2005

A transition from silicon to nanontechnology around the year 2015 is forecast in the biannual International Technology Roadmap for Semiconductors, to be issued Saturday. The report is used by the semiconductor industry as a planning tool to determine how best to spend research and development money for new technology.

Chip for topological quantum computer designed

Rice University physicists have developed a new method for making a “quantum spin Hall topological insulator,” a chip for future quantum computers that are based on “topological quantum computing.”

Topological designs are expected to be more fault-tolerant than other types of quantum computers because each qubit (quantum bit) in a topological quantum computer will be made from a pair of highly stable theoretical quantum particles… read more

Chip design aims for quantum leap

August 23, 2002

University of Wisconsin researchers are designing a practical quantum computer using ordinary electronics rather than exotic laboratory equipment. Their design would incorporate thousands of individually-controlled electrons into a silicon chip that could be made much the same way as today’s computer chips.
