Fire at Renesas' Naka semiconductor fab halts production of 300mm wafers

Renesas Electronics Corporation was struck by a fire in the N3 Building (300mm line) of its Naka Factory (located in Hitachinaka, Ibaraki Prefecture) on March 19, 2021 at 2:47am.

The fire was extinguished on the same day and there no casualties to the employees and no damages to the building. However, Renesas said there was some damage to some of the utility equipment, including its pure water supply, the air conditioning system, as well as to some of the manufacturing equipment. The burned area is approximately 600m2, which is around 5% of the 12,000m2 clean room area of the first floor N3 Building, and the burned manufacturing equipment was 11 units, which is around 2% of the manufacturing equipment of the N3 Building. 


Production at N3 Building (300mm wafers) has temporarily halted while the company cleans the interior of the clean room and procures replacements of the burned equipment.

Renesas aims to resume production within one month. The financial impact from halting the N3 Building production is approximately 17 billion yen per month. 

In a press conference, company officials extended their apologies for the occurrence of the fire, the circumstances and the causes, as well as the outlook going forward. 

"We would like to give our sincerest apologies to neighboring residents, customers, partner companies, relevant authorities and all those involved for the trouble the fire caused,” said Hidetoshi Shibata, President & CEO of Renesas. “In addition, we would like to express our gratitude for the fire department and those who partook in the extinguishing of the fire.”

The production at N2 Building (200mm line) and the WT Building (wafer testing) is operating as usual.

NEC qualifies subsea repeaters and cables for 24 fiber pairs

 NEC and its subsidiary OCC Corporation have completed full qualification of subsea repeaters and optical cable containing up to 24 fiber pairs (FPs) (48 fibers). The new qualification is a 50% improvement in fiber count over the 16 fiber pair systems generally available today. 

Only minor modifications were needed to NEC's existing repeater and cable designs. Keeping NEC's quadruple pump redundancy in the repeater (established more than 10 years ago) and maintaining OCC's outstanding cabling performance has resulted in cabled attenuations lower than 0.150dB/km. Low attenuation is critical to achieve large spectral efficiency as well as lower power consumption.

NEC said the qualification will allow for the construction of subsea telecom cables with superior traffic capacity while reducing the cost per bit of the wet plant. The development is fully in line with SDM (Space Division Multiplexing) system architectures. 

"As global demands for capacity and FP flexibility continue to soar, NEC is committed to helping our customers to build up their subsea networks with large spectral efficiency, lower power consumption and large-scale subsea connectivity," said Yoshihisa Inada, Deputy General Manager and Head of Subsea Technology Development at NEC's Submarine Network Division.  "We continue to evaluate multiple technical options to further increase capacity and reduce the cost/bit of the networks."

OCC's 24 fiber pair cable can be manufactured using a wide range of existing optical fibers, according to the needs of each new cable system. Each fiber can be visually identified using a field-proven combination of ring marking and conventional fiber coloring, first introduced in 2013. Furthermore, in OCC cable, the fiber's transmission performance is completely unaffected, either by the fiber marking or cabling processes.

"We have concluded that the use of our fibers in OCC's 24 pair cable results in a cabled attenuation matching the nominal value. We are confident that our ultra-low-loss fibers can contribute to achieve large capacity, high spectral efficiency and low power consumption in transoceanic networks," said Dr. Masashi Onishi, General Manager at Optical Fiber and Cable division of Sumitomo Electric Industries Ltd.

"To support growing bandwidth, next generation subsea systems will offer Petabit-scale transmission. To achieve the required performance, cabling processes must capture the advantaged optical attenuation and large effective area of our ultra-low-loss fibers. OCC's cabling process for 24 fiber pairs works with our high quality fiber to meet the challenge," said Dr. Bernhard Deutsch, VP & GM, Optical Fiber & Cable, Corning Incorporated.

NEC targets subsea cables to 24 fiber pairs and beyond

NEC and its subsidiary OCC Corporation completed full qualification of subsea repeaters and optical cable containing up to 20 fiber pairs (40 fibers). This represents a 25% improvement in fiber count over 16 fiber pair systems previously built by NEC. NEC said it achieved this milestone with only minor modifications to its proven repeater and cable designs. This was done by optimizing key repeater components, and by proving that its existing cable...

NTT develops quantum random number generator

Researchers at NTT have developed a quantum random number generator (QRNG) that exploits the probabilistic nature of quantum measurements to generate genuine random numbers. 

The breakthrough could be implemented as a server that repeatedly produces fixed blocks of fresh, certifiable, public random bits. Applications might include communication networks with high security enhanced by quantum technologies.

NTT said previous high-performance QRNGs require fully characterized quantum devices, which could be subject to security loopholes. Although there are QRNGs that are secure with realistic devices, they need to run for a long time to accumulate sufficient randomness. This results in high latency from the initial request to the delivery of the requested random bits. It is desirable for real-world applications to realize QRNGs of low latency, high rate and high security. In this work, by developing an efficient method for certifying randomness (a collaborative work with the researchers at the National Institute of Standards and Technology) and by measuring the arrival time of an optical pulse with time-bin encoding, NTT was able toshow that every 0.1 seconds a block of 8192 quantum-safe random bits can be generated, enabling low-latency high-rate performance.
