For the first time, IBM engineers have designed and tested a fully integrated wavelength multiplexed silicon photonics chip, which the company says will soon enable manufacturing of 100 Gb/s optical transceivers (read the press release here). This will allow datacenters to offer greater data rates and bandwidth for cloud computing and Big Data applications.
Early in the program (back in 2007), IBM contributed a piece to ASN about why their photonics program is on SOI – you can read that here. (Most all photonics — except the lasers — are on SOI. You can read more ASN photonics pieces from Intel and others here.)
Silicon photonics greatly reduces data bottlenecks inside of systems and between computing components, improving response times and delivering faster insights from Big Data. IBM’s breakthrough enables the integration of different optical components side-by-side with electrical circuits on a single silicon chip using sub-100nm semiconductor technology.
IBM’s silicon photonics chips uses four distinct colors of light travelling within an optical fiber, rather than traditional copper wiring, to transmit data in and around a computing system. In just one second, this new transceiver is estimated to be capable of digitally sharing 63 million tweets or six million images, or downloading an entire high-definition digital movie in just two seconds.
IBM presented details at the recent 2015 Conference on Lasers and Electro Optics.Posted May 14, 2015 - Share this Buzz
International research teams working on or interested in the far-reaching SOIPIX radiation-detector project have a workshop coming up in June. The project was originally started by KEK* scientists to develop a new detector technology and quantum beam imaging for high-energy particle physics. As research teams around the world (including Japan, USA, China and Europe) joined to take advantage of the multi-wafer project runs, it soon expanded to include more applications. (To learn more about the program, click here.)
Leveraging the SOIPIX strategy of SOI-based monolithic sensor-electronics integration, applications are now being developed in areas such as medical (x-ray sensors and radiotherapeutic systems), materials research, nuclear physics, astrophysics, electron microscopy and industrial uses (such as x-ray inspection systems).
(Here at ASN, we covered the project and its implications for medical imaging back in 2010 – click here to read that piece.)
The next workshop, SOIPIX2015, will take place at Tohoku University (Sendai, Japan) 3-5 June 2015. Registration has been extended until 22 May 2015. Click here for registration information.

A recent GlobalFoundries blog entitled RF-SOI is IoT’s Future, and the Future is Bright (read it here) says, “RF SOI is a win-win technology option that can improve performance and data speed in smartphones and tablets, and it is expected to play a key role in the Internet of Things applications as well.”
The blog touches on the full range of benefits of RF-SOI for front-end integration, resulting in, “… longer battery life, less dropped calls and higher data speeds.” It then goes on to cite complementary advantages of FD-SOI. Peter Rabbeni, GlobalFoundries director of RF Segment Marketing, notes that in FD-SOI, “dynamic control of Vdd and the use of well-bias techniques can not only help reduce overall power consumption but can be used as a means to optimize RF circuit operation. This is not something that can be easily done in bulk technologies.”Posted April 30, 2015 - Share this Buzz

Right on schedule, the SFARDS cryptocurrency ASIC on 28nm FD-SOI has made its debut in silicon, and is surpassing expectations. In what is clearly a stunning success, the company announced that the ASIC’s lowest working voltage is 0.45V. This means it operates stably at a power supply voltage that’s about half that of competing 28nm offerings.
An article published on the SFARDS website (see the whole thing here) said, “Using the latest in FD-SOI processing technology, SFARDS has successfully completed its 28nm SF3301 dual-algorithm ASIC chip. The SF3301 is the world’s first chip to use this manufacturing process and is at the same time the world’s first 28nm dual-algorithm (SHA-256 & Scrypt) chip, capable of mining these two algorithms simultaneously or singularly.
“SFARDS’ SF3301 fully utilizes the advantages of the FD-SOI technology. This brings increased forward body bias; the chip is operational at lower voltage while maintaining a higher frequency. The chip boasts impressive power efficiency while affording high hash power, allowing for much lower wastage per hash. The ASIC’s lowest working voltage is 0.45V.”
As noted in ASN’s Buzz in March 2015 (read it here), cryptocurrency (the best-known example of which is Bitcoin) depends on “ledgers” supported by bitcoin “mining” chips. As well-explained in an arstechnica piece (read it here), while some Bitcoin mining is done on CPUs and GPUs, serious mining requires much faster and lower power ASICs in the hardware.Posted April 21, 2015 - Share this Buzz
CEA-Leti’s newest version of its advanced compact model for FD-SOI is now available in all major SPICE simulators (get the press release here). The Leti-UTSOI2.1 is the latest version of Leti’s compact model for FD-SOI, which was first released in 2013. (Compact models of transistors and other elementary devices are used to predict the behavior of a design. As such, they are embedded in simulations like SPICE that designers run before actual manufacturing. )
Leti-UTSOI2.1 further improves predictability and accuracy. These improvements include a direct and predictive link between bi-dimensional device electrostatics and process parameters, a refined description of narrow-channel effects, improved accuracy of moderate inversion regime and gate tunneling current modeling.
“This new version of the ultra-thin SOI model, which affirms Leti’s continuing leadership in FD-SOI technology, is ideal for designers seeking differentiation in energy management and performance for advanced nodes,” said Leti CEO Marie-Noëlle Semeria
Leti-UTSOI2.1, which considerably extends the domain of physical device description compared to other solutions, is now available in most of the commercial SPICE and Fast SPICE simulators used by industry.Posted April 21, 2015 - Share this Buzz
In a new YouTube video, Samsung’s Sr. Director of Foundry Marketing, Kelvin Low, makes a strong case for 28nm FD-SOI, especially for ultra-low-power, IoT, wearables, networking and automotive apps. The five-minute video was taped by ChipEstimate.TV host Sean O’Kane during the Cadence User Conference (CDNLive, Silicon Valley, March 2015 – click here to see it). While the first half addresses 14nm FinFET, starting at the 2:25 mark, it’s all about FD-SOI.
First Kelvin reminds viewers that 28nm will be a long-lived node thanks to its lower costs and the fact that it doesn’t use double patterning. He says Samsung has acquired a number of customers for FD-SOI, and now has the complete ecosystem to support the process technology, from substrate suppliers through the design chain. The key value, he says, is in the extremely low power operation and the low power supply voltage, which translates into long battery life for IoT and wearables. He also says he’s very excited by the prospects for FD-SOI in the automotive domain, where it is especially valued for its enhanced reliability.Posted April 9, 2015 - Share this Buzz

At the time of this post, tape out of the company’s SF3301ASIC has been announced as complete. Cryptocurrency (the best-known example of which is Bitcoin) depends on “ledgers” supported by bitcoin “mining” chips. As noted in an arstechnica piece (read it here), while some Bitcoin mining is done on CPUs and GPUs, serious mining requires much faster and lower power ASICs in the hardware.
As posted on the SFARD blog, “By using FDSOI technology not currently present in any other chip on the market, power efficiency when mining with SHA-256 is predicted to reach below the 0.3 J/GH range, and 2.0 J/MH when mining with Scrypt.
“The SF3301 is extremely versatile, allowing you to mine multiple currencies with one device. This means price fluctuations can be harnessed and being forced to turn off your miner is far less likely.
“A condition can arise where altcoins are utilized to cover electricity costs while bitcoin is continuously and simultaneously being mined. This ability is something never seen before with 28nm technology.”Posted March 11, 2015 - Share this Buzz
