New production method could enable everything from more efficient computer displays to enhanced biomedical testing.
CAMBRIDGE, Mass. — Quantum dots — tiny particles that emit light in a dazzling array of glowing colors — have the potential for many applications, but have faced a series of hurdles to improved performance. But an MIT team says that it has succeeded in overcoming all these obstacles at once, while earlier efforts have only been able to tackle them one or a few at a time.
Quantum dots — in this case, a specific type called colloidal quantum dots — are tiny particles of semiconductor material that are so small that their properties differ from those of the bulk material: They are governed in part by the laws of quantum mechanics that describe how atoms and subatomic particles behave. When illuminated with ultraviolet light, the dots fluoresce brightly in a range of colors, determined by the sizes of the particles.
First discovered in the 1980s, these materials have been the focus of intense research because of their potential to provide significant advantages in a wide variety of optical applications, but their actual usage has been limited by several factors. Now, research published this week in the journal Nature Materials by MIT chemistry postdoc Ou Chen, Moungi Bawendi, the Lester Wolfe Professor of Chemistry, and several others raises the prospect that these limiting factors can all be overcome.
The new process developed by the MIT team produces quantum dots with four important qualities: uniform sizes and shapes; bright emissions, producing close to 100 percent emission efficiency; a very narrow peak of emissions, meaning that the colors emitted by the particles can be precisely controlled; and an elimination of a tendency to blink on and off, which limited the usefulness of earlier quantum-dot applications.

ARM (LSE: ARM) (NASDAQ: ARMH) and Cadence Design Systems, Inc. (NASDAQ: CDNS) announced the tape-out of the first 14-nanometer test chip implementation of the high-performance ARM® Cortex™-A7 processor, the most energy-efficient applications processor from ARM. Designed with a complete Cadence® RTL-to-signoff flow, the chip is the first to target Samsung’s 14-nanometer FinFET process, accelerating the continuing move to high-density, high-performance and ultra-low power SoCs for future smartphones, tablets and all other advanced mobile devices.

Harry Luan, chief technology officer at Kilopass Technology Inc., a leading provider of semiconductor logic non-volatile memory (NVM) intellectual property (IP) presenting “Novel New Vertically-Oriented, Antifuse Non-Volatile Memory Bit Cell” at MemCon 2012 on Tuesday, September 18, at 2:15 p.m. at the Santa Clara Convention Center, Santa Clara, Calif.
The new embedded VCM (Vertical Cross-point Memory) NVM IP bit cell quadruples the density of today’s anti-fuse NVM IP bit cell. The VCM bit cell will make possible program storage where today’s embedded non-volatile memory (eNVM) technology is cost-prohibitive or unavailable at capacities of 4Mb to 32Mb. It will also enable a higher level of performance more similar to SRAM compared to existing slower eNVM technologies or external flash or EEPROM chips.

MIT team applies technology developed for visual ‘cloaking’ to enable more efficient transfer of electrons.
A new approach that allows objects to become “invisible” has now been applied to an entirely different area: letting particles “hide” from passing electrons, which could lead to more efficient thermoelectric devices and new kinds of electronics.
The concept — developed by MIT graduate student Bolin Liao, former postdoc Mona Zebarjadi (now an assistant professor at Rutgers University), research scientist Keivan Esfarjani, and mechanical engineering professor Gang Chen — is described in a paper in the journal Physical Review Letters.
Normally, electrons travel through a material in a way that is similar to the motion of electromagnetic waves, including light; their behavior can be described by wave equations. That led the MIT researchers to the idea of harnessing the cloaking mechanisms developed to shield objects from view — but applying it to the movement of electrons, which is key to electronic and thermoelectric devices.

I was speaking with experts at Mentor about the latest developments in back-end physical verification (PV) and design-for-manufacturing (DFM). It prompted me to take a look at what has changed and what will be essential going forward. Here is what I see for this critical area for IC implementation.
First, we have passed the 28nm barrier and are already looking to a new generation of design. Leading-edge design starts are now at 20nm and we will see production silicon for that node by early 2013. However, in a new research brief, “Driving first-time silicon success across the IC ecosystem,” by Dr. Handel Jones, semiconductor analyst at IBS, the total number of design starts is not growing. While System integrators such as Samsung and Apple, are furiously growing their mobile businesses, the ability to integrate ever-larger collections of IP in their SOCs means they do not need to include more ICs in their phones to expand the features of their products. It is also true that 20nm designs have a much higher NRE than previous generations. Naturally, this economic incentive will keep some design starts at the 28nm and larger nodes.

Before I step on stage for a performance, I look at the crowd and say, “Lord, please don’t let me screw this up.” But it is the effort before this performance that really leads to this moment. First we have a casting process, where we try to find the best actor to play the lead, then the understudy, then the extras and technical team etc. This is usually done by a director, someone who has excelled at acting before, and develops the entire vision. Then we memorize our lines, this is the most mind-numbing and difficult part, so to prevent mental break downs, we divide the script up into smaller parts. We start with a few simple lines, then progressively add more lines and difficulty of memorization. Then we block the entire play, see what goes where, and perform it. Next, we have dress rehearsals, we get comfortable performing in our costumes and make sure things go off without a hitch. Now after all of this, we present it to the audience and hope that we don’t get pelted with tomatoes. After we perform, we wait for the audience to react, if they respond with cheers, we repeat the act the same way the next night with minor adjustments, if we are hurt and killed with articles of food, we then see what to improve and make changes for the next show.
