Will 7nm And 5nm Really Happen?


Today’s silicon-based finFETs could run out of steam at 10nm. If or when chipmakers move beyond 10nm, IC vendors will require a new transistor architecture. III-V finFETs, gate-all-around FETs, quantum well finFETs, SOI finFETs and vertical nanowires are just a few of the future transistor candidates at 7nm and 5nm. Technically, it’s possible to manufacture the transistor portions of the... » read more

Stacked Die Are Coming Soon. Really


Since the beginning of the decade there have been many predictions that stacked die were just over the hill, but the time it has taken to climb that hill has been longer than most people would have anticipated. In fact, TSMC has been fully capable of building stacked die since last year, with risk production expected to be completed by year, according to Gartner. But something very fundament... » read more

A cup of sub-wavelength images The National Institute of Standards and Technology (NIST) and the University of Michigan have developed a technology that could enable sub-wavelength images at radio frequencies. Researchers used a mere glass cup, and laser light at optical wavelengths, to measure and image RF fields. In the future, this technology could measure the behavior of metamaterials. ... » read more

Will 7nm And 5nm Really Happen?


As leading-edge chipmakers continue to ramp up their 28nm and 20nm devices, vendors are also updating their future technology roadmaps. In fact, IC makers are talking about their new shipment schedules for 10nm. And GlobalFoundries, Intel, Samsung and TSMC are narrowing down the options for 7nm, 5nm and beyond. There is a high probability that IC makers can scale to 10nm, but vendors face a ... » read more

Has The IC Industry Hit A ‘Red Brick Wall’?


In the mid-1980s, the semiconductor industry was in a crisis. Chipmakers were looking for ways to break the magical one-micron barrier. Many thought X-ray lithography would be required to break the barrier, but as it turned out, traditional optical technology did the trick. And the industry marched on. Then, in 2000 or so, the IC industry was nearing the so-called “red brick wall,” which... » read more

Manufacturing Bits: June 10


At the recent ITF Brussels 2014 event in Belgium, Imec and its partners described a plethora of new technologies in several arenas. Here’s just a small sample of what Imec and others are working on: Hyperspectral imaging cameras Imec and Ximea have devised the world’s smallest hyperspectral imaging camera. Hyperspectral cameras divide the light spectrum into many small wavelength bands.... » read more

Imec Launches R&D Tool Hub


The semiconductor industry is entering yet another inflection point. Consumers want faster mobile systems with more functions. So, chipmakers are under pressure to deliver new and low-power chips that are smaller and faster. The problem is that IC design and chip manufacturing costs continue to escalate. These costs, in turn, are fueling an ongoing shakeout in the chip and fab tool industrie... » read more

World’s thinnest TFTs The U.S. Department of Energy’s Argonne National Laboratory has devised the world’s thinnest flexible, 2D thin-film transistors (TFTs). The transistors are just 10 atomic layers thick. TFTs are typically used in screens and displays. In the lab, Argonne researchers fabricated the TFTs on both a conventional silicon platform and a flexible substrate. [caption i... » read more

Manufacturing Bits: May 20


Brain chips Pennsylvania State University has developed a technology that could enable futuristic biochips, namely those that mimic the human brain. In the lab, Penn State combined a thin film of vanadium dioxide (VO2) on a titanium dioxide substrate to create an oscillating switch. VO2 is an exotic material that exhibits semiconductor-to-metal transitions at 68 °C. In the R&D stage fo... » read more

Time To Revisit 2.5D And 3D


Chipmakers are reaching various and challenging inflection points. In logic, many IC makers face a daunting transition from planar transistors at 20nm to finFETs at 14nm. And on another front, the industry is nearing the memory bandwidth wall. So perhaps it’s time to look at new alternatives. In fact, chipmakers are taking a hard look, or re-examining, one alternative—stacked 2.5D/3D chi... » read more
