Samsung charts progress from 10nm to 3mm Gate-All-Around

Samsung Electronics is making rapid progress in 3nm Gate-All-Around (GAA) process technology, which could see first tape out in 2021 and mass market production as early as 2022.

Compared to 7nm technology, Samsung’s 3GAE process aims to deliver a 45% reduction in chip area with 50% percent lower power consumption, and 35% higher performance, potentially benefiting applications as diverse as mobile, network, automotive, Artificial Intelligence (AI) and IoT.   Samsung's GAA MBCFET (Multi-Bridge-Channel FET) uses a nanosheet architecture, enabling greater current per stack. WhileFinFET structures must modulate the number of fins in a discrete way, MBCFET™provides greater design flexibility by controlling the nanosheet width.

At Samsung Foundry Forum event in Santa Clara California, company executives outlined the fabrication roadmap from today's 10nm down to 3nm. Some highlights:

• 14/10nm - these are in high volume manufacturing. These will remain long-lasting technologies into the future
• 8nm - the most advanced non-EUV technology
• 7nm FinFET - currently under mass production for mobile applications. The first tape out was in 2018. IP re-use is supported.
• 6nm FinFET -- mass production of 6nm process devices in the second half of 2019
• 5nm FinFET - the product design of Samsung’s 5nm FinFET process, which was developed in April, is expected to be completed in the second half of this year and go under mass production in the first half of 2020
• 4nm FinFET - will represent the maximum scaling of the 7nm family, and development will be completed later this year - 
• 3nm Gate-All-Around (GAA) process development is on track and will leverage MBCFET (Multi-Bridge-Channel FET) based on nanosheet technology. A Process Design Kit (PDK) version 0.1 for 3GAE was released in April. This will be the future beyond FinFET.

“We stand at the verge of the Fourth Industrial Revolution, a new era of high-performance computing and connectivity that will advance the daily lives of everyone on the planet,” said Dr. ES Jung, President and head of Foundry Business at Samsung Electronics. “Samsung Electronics fully understands that achieving powerful and reliable silicon solutions requires not only the most advanced manufacturing and packaging processes as well as design solutions, but also collaborative foundry-customer relationships grounded on trust and shared vision. This year’s Foundry Forum is filled with compelling evidence of our commitment to progress in all those areas, and we’re honored to host and converse with our industry’s best and brightest,” Dr. Jung added.

Vodafone UK to launch 5G on 3 July 2019

Vodafone announced plans to activate its commercial 5G network for both consumers and business customers in seven cities across the UK on 3 July 2019. Launch cities are Birmingham, Bristol, Cardiff, Glasgow, Manchester, Liverpool and London.

Vodafone's 5G pricing will be the same as 4G for both consumers and business customers.

Vodafone expects to launch 5G roaming in the UK, Germany, Italy and Spain over the summer.
Vodafone UK CEO Nick Jeffery said: “We started our 5G journey more than three years ago. We led the way in setting 5G standards to ensure phones and networks work well together. We upgraded our masts to be able to take 5G without disruption. And we were the first UK company to test 5G over our all-fibre core fixed and mobile network.

UK operators: Huawei ban would bring heavy cost

Saturday, April 06, 2019  UK  

A restriction placed on Huawei in the telecom supply chain could delay a full 5G launch by between 18 and 24 months and cost the UK economy between £4.5bn and £6.8bn, according to a study published by Mobile UK, which is the trade association for the UK’s mobile network operators -  EE, O2, Three and Vodafone. The study argues that a delay to 5G rollout while operators make alternative procurement arrangements with other suppliers may seriously...

SiTime ships MEMS Super-TCXOs for 5G radio synchronization

SiTime announced volume production of its Elite Platform of temperature-compensated oscillators (TCXOs) that provide high stability and dynamic performance at 105°C for IEEE 1588-based synchronization in 5G/4G+ radios and enable wireless service providers to begin their network overhaul.

SiTime's Elite Super-TCXOs leverage its unique DualMEMS temperature sensing and TurboCompensation technologies. The SiT5356/7 MEMS Super-TCXOs deliver dynamic performance for timing stability in the presence of environmental stressors due to air flow, temperature changes, vibration, shock, and electromagnetic interference. The SiT5356/7 can be factory-programmed to many combinations of frequency, stability, voltage, and pull range. This programmability enables designers to optimize the clock configuration while significantly reducing the lead-time and customization costs associated with quartz TCXOs where each frequency is custom built. The device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO.

“5G is expected to revolutionize the data economy but first it is re-writing the rules for wireless network deployment,” said Piyush Sevalia, executive vice president of marketing at SiTime. “5G radios will be deployed in outdoor environments – on lamp posts, buildings, traffic lights – with exposure to heat and rapid temperature changes that can cause loss of radio synchronization, which can disrupt services like advanced driver assistance systems and telemedicine. Unlike other timing vendors, SiTime takes a systems approach to solve these problems. We optimize our SiT5356/7 Super-TCXO system of MEMS, analog, advanced packaging and temperature compensation to deliver industry-leading performance of ±100 ppb stability and ±1 ppb/°C frequency slope (ΔF/ΔT) over -40°C to 105°C. We believe that radios with SiTime’s Super-TCXOs will minimize disruptions to 5G/4G+ services and ensure a better user experience.”

Dell'Oro: Huawei and Samsung gain share in RAN

The mobile infrastructure radio access network (RAN) market is off to a good start in 2019, according to a new report from Dell'Oro Group. Faster than expected uptake of Massive MIMO and 5G NR added fuel to the upswing that began in the second half of 2018.

"The upswing that began in the second half of 2018 extended into 1Q 2019 as market conditions continued to improve fueled by synchronized growth across China, U.S., and Korea to address data traffic growth, low-band LTE coverage expansions, and initial 5G NR deployments," said Stefan Pongratz, Senior Director with the Dell'Oro Group. "Even though we have not made any material adjustments to the overall short-term outlook, it is worth noting that 5G NR Massive MIMO shipments developed at a faster pace than expected in the quarter while the price points for these 5G NR Massive MIMO systems are trending at lower levels than we had initially projected, changing the upside and downside risks to the short-term forecast," continued Pongratz.

Following are additional highlights from the 1Q 2019 RAN report:

• Huawei and Samsung recorded the largest overall RAN revenue share gains Y/Y.
• North America and the Asia Pacific regions are projected to lead the RAN market in 2019.
• Massive MIMO transceiver shipments expected to eclipse 20 Million in 2019.
