Qualcomm just announced the biggest chip acquisition ever
The smartphone world is starting to slow, and the companies that make the chips that go inside them are teaming up to stave off dwindling profits. Perhaps that's why Qualcomm today announced that it's picking up NXP Semiconductor for $47 billion, in what is set to become the biggest ever semiconductor deal.
Samsung lets inspectors into its factories following deaths
Samsung has agreed to allow inspectors into its plants as part of a deal with plant workers who contracted cancer and other workplace maladies. The company signed the document with two groups that represent ailing workers and their families. All three sides chose a labor law professor as ombudsman to head up and choose the inspection team, and checks will run for three years, with an option for three more. The company also agreed to disclose more info on chemicals it uses in its chip and display plants, and will open a clinic for workers.
Army scientists build smaller, tougher, cheaper solar cells
Army researchers at the Redstone Arsenal have announced a significant breakthrough in solar energy production. They've created a photovoltaic solar panel that is smaller, more robust and less expensive to build and operate than any other panel currently available. Virtually every solar panel currently in existence relies on a pure silicon construction, however the band gap (the wavelength of light that it can actually be absorbed and converted into electricity) of single crystal silicon is exceedingly narrow compared to the full spectrum shining down from the Sun. Not only does this mean that conventional panels are missing out on potential power, the ultraviolet and infrared wavelengths actively damage the panels by causing them to heat, warp and crack.
Fujitsu to merge LSI chip business with Panasonic, cut 5,000 jobs
Intense semiconductor competition has already forced numerous Japanese companies to work together, and now Fujitsu has announced that it'll merge its LSI chip design and R&D divisions with Panasonic. The two companies are looking to the state-run Development Bank of Japan to fund the new venture, which comes in the wake of expected Fujitsu losses of over $1 billion this year -- forcing the company to cut 5,000 jobs and transfer 4,500 to other divisions by March 31st. Fujitsu said it's also looking to transfer a state-of-the-art LSI fabrication line in central Japan to a new foundry venture with Taiwan Semiconductor Manufacturing, the world's largest chip maker. That carries on a trend in declining Japanese chip dominance, exemplified by Elpida's bankruptcy and the recent government bailout of Renesas, which itself is a merger of NEC, Hitachi and Mitsubishi's semiconductor operations.

New process for nanotube semiconductors could be graphene's ticket to primetime (video)
In many ways, graphene is one of technology's sickest jokes. The tantalizing promise of cheap to produce, efficient to run materials, that could turn the next page in gadget history has always remained frustratingly out of reach. Now, a new process for creating semiconductors grown on graphene could see the super material commercialized in the next five years. Developed at the Norwegian University of Science and Technology, the patented process "bombs" graphene with gallium, which forms droplets, and naturally arranges itself to match graphene's famous hexagonal pattern. Then, arsenic is added to the mix, which enters the droplets and crystallizes at the bottom, creating a stalk. After a few minutes of this process the droplets are raised by the desired height. The new process also does away with the need for a (relatively) thick substrate to grow the nanowire on, making it cheaper, more flexible and transparent. The inventors state that this could be used in flexible and efficient solar cells and light emitting diodes. We say forward the revolution.
IBM creates consistent electron spin inside semiconductors, takes spintronics one twirl closer
A fundamental challenge of developing spintronics, or computing where the rotation of electrons carries instructions and other data rather than the charge, has been getting the electrons to spin for long enough to shuttle data to its destination in the first place. IBM and ETH Zurich claim to be the first achieving that feat by getting the electrons to dance to the same tune. Basing a semiconductor material on gallium arsenide and bringing the temperature to an extremely low -387F, the research duo have created a persistent spin helix that keeps the spin going for the 1.1 nanoseconds it would take a normal 1GHz processor to run through its full cycle, or 30 times longer than before. As impressive as it can be to stretch atomic physics that far, just remember that the theory is some distance from practice: unless you're really keen on running a computer at temperatures just a few hops away from absolute zero, there's work to be done on producing transistors (let alone processors) that safely run in the climate of the family den. Assuming that's within the realm of possibility, though, we could eventually see computers that wring much more performance per watt out of one of the most basic elements of nature.
Researchers make unsuitable parts work as solar cells, could lead to cheaper panels
Harnessing the power of the sun is a tricky business, but even the past few weeks have seen some interesting developments in the field. In this latest installment, researchers from the Lawrence Berkeley National Laboratory and the University of California have figured out a way of making solar cells from any semiconductor, potentially reducing the cost of their production. You see, efficient solar cells require semiconductors to be chemically modified for the current they produce to flow in one direction. The process uses expensive materials and only works with a few types of semiconductors, but the team's looking at using ones which aren't normally suitable -- the magic is to apply an electrical field to them. This field requires energy, but what's consumed is said to be a tiny fraction of what the cell's capable of producing when active, and it means chemical modification isn't needed. The concept of using a field to standardize the flow of juice isn't a new one, but the team's work on the geometrical structure of the cells has made it a reality, with a couple of working prototypes to satisfy the skeptics. More of these are on the way, as their focus has shifted to which semiconductors can offer the best efficiency at the lowest cost. And when the researchers have answered that question, there's nothing left to do but get cracking on commercial production. For the full scientific explanation, hit up the links below.
Intel to buy 15 percent of silicon fab equipment maker ASML, wants manufacturing machines made faster
Chipzilla didn't get its position as the king of semiconductors by twiddling its thumbs, folks. It became a Valley behemoth by delivering us faster and better silicon, and its latest $4.1 billion purchase -- a 15 percent stake in silicon manufacturing equipment maker ASML Holding NV -- should help keep Intel atop the CPU heap. You see, Intel's in the process of retooling its chip manufacturing process to use bigger diameter silicon wafers, which'll make those Ivy Bridge, ValleyView and other future chips cheaper for all of us. Such retooling can take years to implement, which is likely why Intel was willing to plunk down so much cash to ensure nothing futzes with its manufacturing timetable. The company's investment will presumably give it the clout to get ASML's crucial lithography equipment on the fast track to completion. Hop to it, fellas, we want our CPUs at bargain-basement prices, and we want them now.
Qualcomm enlists Samsung, UMC to help meet 28nm Snapdragon S4 demand
Qualcomm's Snapdragon S4 chipset is certainly hot (well, not too hot), but it looks like demand is expected to grow even further, causing the San Diego-based SoC maker to turn to allies in the east to help beef up supply. According to China Economic News Service, United Microelectronics Corp. (UMC) and Korea-based Samsung will join Taiwan Semiconductor Manufacturing Co. (TSMC) to manufacturer the 28nm chips beginning later this year, in an attempt to increase S4 availability ahead of the Windows RT launch. The article cites Qualcomm CEO Paul Jacobs as saying that a shortage is expected to continue, due to the complicated techniques necessary to manufacturer 28nm chips, and that the company may consider adding its own manufacturing plant in the future. All in all, it doesn't seem like a terrible position for QCOM to be in. Full details are at the Taiwanese source link below.
Micron scoops up Elpida Memory, 50-percent production boost for $2.5 billion
There's no question that Micron has shifted its focus away from PCs in favor of producing components, shipping everything from SSDs to CMOS sensors in recent years, but the semiconductor manufacturer just took a $2.5 billion step even closer to bridging its gap between other companies in the same market, including Samsung, the chip producer's top competitor. Under the deal, Elpida Memory, which is headquartered in Tokyo, will fall within the Idaho-based conglomerate's growing umbrella, netting Micron a 50-percent boost in production capability. That increase did come at great expense, however -- the transaction included $750 million in cash and $1.75 billion in future installments (1,750 easy payments of one million dollars?), which are set to continue through 2019. The acquisition was also paired with a 24-percent stake in Rexchip Electronics for an additional $334 million, which will complement Elpida's investment, yielding a total 89-percent stake for Micron. While the amount does seem quite significant, investors appear to be on board, with Micron's stock ($MU) currently up more than 4 percent since this morning. Both deals will reportedly close within the next year.
Researchers use lasers to supercool semiconductor membranes, blow your mind
Ah, lasers. Those wonderful, super intense beams of light that we've seen used in headlights, projectors, and naturally, death rays. Like us, researchers at the Niels Bohr Institute at the University of Copenhagen figure there's nothing lasers can't do, and have figured out a way to use them to cool a bit of semiconducting material. This bit of black magic works using a membrane made of gallium arsenide and is based upon principles of quantum physics and optomechanics (the interaction between light and mechanical motion).Turns out, when a one millimeter square membrane of gallium arsenide is placed parallel to a mirror in a vacuum chamber and bombarded with a laser beam, an optical resonator is created between them that oscillates the membrane. As the distance between the gallium arsenide and the mirror changes, so do the membrane's oscillations. And, at a certain frequency, the membrane is cooled to minus 269 degrees Celsius -- despite the fact that the membrane itself is being heated by the laser. So, lasers can both heat things up and cool them down simultaneously, and if that confuses you as much as it does us, feel free to dig into the science behind this paradoxical bit of research at the source below. In other news, left is right, up is down, and Eli Manning is a beloved folk hero to all Bostonians.
Apple now the largest buyer of semiconductors according to Gartner
No one would be shocked to learn that Apple is a major purchaser of semiconductors. Heck, hearing that the company is number one on that list might not even raise too many eyebrows. But, what if you we told you last year the Cupertino crew wasn't the biggest purchaser, or even the second. In 2010 the House that Jobs Built was a distant third behind Samsung and HP but, following a significant surge thanks to the iPad 2 and the updated MacBook Air, its bumped those companies back a slot. In 2011 Apple increased its semiconductor spending by 34.6 percent, from $12.8 billion to $17.3 billion. Samsung stayed in the number two spot with a 9.2 percent jump in spending to $16.68 billion. Meanwhile HP dropped from first, spending only $16.62 billion and settling for the bronze. Check out the source link for the complete rankings from Gartner.
New quantum tunneling transistors to make PCs less power-hungry
Yes, that awesome new 8-core chip in your PC is the fastest thing on the block, but it's got your utility meter spinning accordingly. Fortunately, researchers from Penn State have come up with a new high performance transistor that may turn future chips from power hogs into current-sipping silicon. The group, in cooperation with semiconductor manufacturer IQE, has created a high-performance transistor capable of significantly reducing power demand whether it's idle or switching. Doctoral candidate Dheeraj Mohata's the one who made it happen by inventing an alternative to traditional MOSFET (metal-oxide semiconductor field-effect transistors) technology capable of turning on and off using far less power. Mohata's method uses a tunneling field effect transistor crafted from dissimilar semiconductor materials to provide instant on-off capability at 300 millivolts -- compared to MOSFET's one volt requirement -- to provide a power savings of 70 percent. You can dig deeper into the technical transistor details at the source, but all you really need to know is that the ladies love a PC with paltry power consumption.
First molybdenite IC delivers silicon-crushing, chip-shrinking, graphene-blasting action
Never heard of molybdenite? We're not shocked. Its not nearly as hyped as graphene or quantum dots, but it could be the key to smaller, bendable microchips. The problem with silicon is that, in layers less than two nanometers thick, it can become unstable, oxidize and quickly deteriorate. Molybdenum disulfide (MoS2), on the other hand, can be laid down in sheets just three atoms thick. The semiconductor also earns bonus points for being an abundant, naturally occurring mineral. Earlier this year researchers at the Laboratory of Nanoscale Electronics and Structures (LANES) demoed the first molybdenite transistor, but the team is moving fast and has already whipped up the first prototype of a complete integrated circuit (we assume with the aid of an all girl army of Kung Fu engineers). Things are looking good for this potential silicon usurper. And best of all, molybdenite is flexible. So, hello bendable computers!
Texas Instruments wraps up purchase of National Semiconductor
In April, Texas Instruments announced its intention to snatch up National Semiconductor for a cool $6.5 billion. Now, almost six months later, the acquisition is complete and TI can tack another few percentage points on to its already market-leading chunk of the analog chip market. At least for now, National will operate as a branch of TI's analog division, which now accounts for over 50-percent of the company's revenue, and keep its (reasonably) well known brand name alive. For a few more details on the deal, check out the PR after the break.
IBM and 3M join forces to fab 3D microchips, create mini-silicon skyscraper valley
3D hype is fast wearing out its welcome, but there's at least one area of industry where the buzzed about term could usher in true innovation. Announced today as a joint research project, IBM and 3M will work towards the creation of a new breed of microprocessors. Unlike similar three-dimensional semiconductor efforts by Intel, the two newly partnered outfits plan to stack up to 100 layers of chips atop one another resulting in a microchip "brick." Under the agreement, IBM will contribute its expertise on packaging the new processors, while 3M will get to work developing an adhesive that can not only be applied in batches, but'll also allow for heat transfer without crippling logic circuitry. If the companies' boasts are to be believed, these powerhouse computing towers would cram memory and networking into a "computer chip 1,000 times faster than today's fastest microprocessor enabling more powerful smartphones, tablets, computers and gaming devices." That's a heady claim for a tech that doesn't yet exist, but is already taking swings at current faux 3D transistors. Official presser and video await you after the break.
Samsung's Q2 profit drops 26 percent due to sluggish TV sales, demand for phones explodes
You may or may not have noticed, but we're once again in the thick of earnings season, and today Samsung's in the hot seat. The company has reported that its second-quarter profit fell 26 percent year-over-year to 3.7 trillion won ($3.5 billion), largely thanks to underwhelming sales of flat screen TVs and, to a lesser extent, semiconductors. That's a shade worse than the whiz kids over on Wall Street were expecting, according to Bloomberg. In fact, the demand for televisions was so disappointing that it overshadowed what was actually an impressive quarter for the outfit's mobile division -- sales of feature and smartphones quadrupled year-over-year to 19.2 million units, putting the company on track to further narrow the gap with Nokia, the world's bestselling handset maker. All told, this balanced out to a modest growth in revenue -- an uptick of 2.9 percent to 39 trillion won ($36.7 billion).
Apple's A6 processor may come courtesy of TSMC, Samsung left to wonder why
Apple's fondness for anorexic handhelds knows no bounds, and if this alleged deal with the Asian foundry holds water, expect to see its waistband tighten further. Rumoured back before the iPad 2 launch, the house-that-Steve-built's reportedly been eyeing Taiwanese Semiconductor Manufacturing Corp to produce an 'A6' for its upcoming iPhone refresh. While it's easy to dismiss this purported move as a direct diss to Samsung, what's more likely is that Cupertino's engaging in a competitive bit of size does matter -- specifically, the A5's 45nm process. A transition to newer, lower power 28nm ARM chips would give Jonathan Ives' employer a distinct market advantage, dwarfing even TSMC's current 40nm in the process. While it's all still just speculation for now, only time and an iPhone 5 tear-down will tell for sure.
Texas Instruments to acquire National Semiconductor for $6.5 billion in cash money
As the saying goes, everything's bigger in Texas, and that includes Texas Instruments' (TI) share of the semiconductor market. The Dallas-based firm announced today that it will pay $6.5 billion for National Semiconductor. With the acquisition complete, National will become a branch of TI's analog segment, which is now positioned to make up 50 percent of the company's revenue. According to a joint press release, TI held the biggest chunk of the analog semiconductor market in 2010 at 14 percent, and with the new addition that number's bound to get even bigger. Full PR after the break.
IBM forms new partnership with ARM in hopes of developing ludicrously small chip processing technology
We've seen IBM and ARM team up before, but this week both companies announced a new joint initiative to develop 14nm chip processing technology. That's significantly smaller than the 20nm SoC technology ARM hopes to create in partnership with TSMC, and makes the company's previous work with IBM on 32nm semiconductors look like a cake walk. The potential benefits, though, are faster processors that require less power, and feature lower per unit manufacturing costs Who knows if or when we'll see tangible results from the tag team, but if IBM's Watson can beat Jeopardy champions, further reducing the average size of a feature that can be created on a chip should be elementary, right? To read over the full announcement check out the press release after the break.
