Power/Performance Bits: March 29
By Jesse Allen - 29 Mar, 2016 - Comments: 0

Photonic-phononic circuit Researchers at the National Institute of Standards and Technology (NIST) developed a piezo-optomechanical circuit that converts signals among optical, acoustic and radio waves. At the heart of the piezoelectric optomechanical circuit is an optomechanical cavity, which consists of a suspended nanoscale beam. Within the beam are a series of holes that act like a ha... » read more

Superconducting memory A group of scientists from the Moscow Institute of Physics and Technology and the Moscow State University developed a fundamentally new type of memory cell based on superconductors, which they believe will be able to work hundreds of times faster than memory devices commonly used today. The basic memory cells are based on quantum effects in "sandwiches" of supercond... » read more

Do-it-yourself optoelectronics The University of Illinois at Urbana-Champaign has developed a technology to make optical components on a do-it-yourself basis. To make a component, researchers have devised what they call plasmon-assisted etching. The process makes use of a nanostructured template, which can be used to create optical components. The template is a 2D array of gold pillar-su... » read more

Measuring FinFETs Will Get Harder
By Mark LaPedus - 19 Nov, 2015 - Comments: 2

The industry is gradually migrating toward chips based on finFET transistors at 16nm/14nm and beyond, but manufacturing those finFETs is proving to be a daunting challenge in the fab. Patterning is the most difficult process for finFETs. But another process, metrology, is fast becoming one of the biggest challenges for the next-generation transistor technology. In fact, [getkc id="252" kc_n... » read more

Lightweight Cryptography For The IoE
By Ernest Worthman - 03 Sep, 2015 - Comments: 0

This is the age where technology is expected to do more, faster, anonymously, and often invisibly. And it's supposed to use less power, with smaller footprints, unobtrusively and intuitively. And all that needs to be protected with cryptography. That's the goal, at least. But as Simon Blake-Wilson, vice president of products and marketing for [getentity id="22671" e_name="Rambus"]' Cryptogra... » read more

System Bits: Aug. 25

Quantum computer building block In a finding that could ultimately be used to produce key components of quantum computers in the future, a team of researchers led by MIT have analyzed an exotic kind of magnetic behavior, driven by the mere proximity of two materials, using a technique called spin-polarized neutron reflectometry. This discovery could also be used to probe a variety of exotic... » read more

Gaps In Metrology Could Impact Yield
By Mark LaPedus - 17 Apr, 2014 - Comments: 0

For some time, chipmakers have been developing new and complex chip architectures, such as 3D NAND, finFETs and stacked die. But manufacturing these types of chips is no simple task. It requires a robust fab flow to enable new IC designs with good yields. In fact, yield is becoming a more critical part of the flow. Yield is a broad term that means different things to different parts of the ... » read more

Redefining The Kilogram In 2011, the General Conference on Weights and Measures approved 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), according to the National Institute of Standards and Technology (NIST), part of the U.S. Department of Commerce. NIST has taken steps t... » read more

Manufacturing Bits: Sept. 10

Rock Around The Clock National Institute of Standards and Technology’s two experimental atomic clocks have set a new record for stability. Resembling a pendulum or metronome, NIST’s atomic clocks can swing back and forth with perfect timing for a period comparable to the age of the universe. The clocks are based on ytterbium atoms. The clock ticks are stable to within less than two part... » read more
