Huawei unveils automotive-grade high-performance LiDAR and establishes pilot production line-cnTechPost

Huawei on Tuesday released automotive-grade high-performance LIDAR products and solutions for the automotive industry, enabling the detection of pedestrians and vehicles in urban areas.
Compared with millimeter wave radar and cameras, LIDAR has stronger capabilities in target contour measurement, angle measurement, light stability, and universal obstacle detection.
Non-regulated pedestrians, non-regulated roads, and even non-regulated driving in urban areas urgently need LIDAR to solve these difficult scenarios.

According to Duan Zhongyi, general manager of Huawei's fusion sensing product department, Huawei designed and developed this 96-line medium-long range LIDAR product, which can achieve urban pedestrian-vehicle detection coverage.

It also has both high-speed vehicle detection capability, which is more in line with scenarios in China's complex road conditions, according to Duan.
LIDAR is an optomechanical product that requires deep integration of multiple fields of optomechanics. Thanks to its long-term accumulation of optical design, signal processing, and overall engineering in ICT, Huawei has reconstructed the core components of LIDAR, including the transmitter module, receiver module, and scanner.

Huawei has established the first Pilot production line for automotive-grade LiDAR, which will be geared toward million-level mass production needs.
Huawei says it is already pushing ahead with an annual production capacity of 100,000 sets/line to accommodate future mass production demand.
BAIC's premium new energy brand ARCFOX then announced that its latest HBT model will be the first in the world to be equipped with Huawei's LIDAR.
Earlier, Yu Liguo, deputy general manager of BAIC New Energy and president of ARCFOX BU, said that the new HBT vehicle will be equipped with three 96-line LiDARs.

Hi WTAN,

Any news you can share regarding the delivery of SMEE 28nm DUVL to SMIC? When will it start operating? and also the status of SMIC 7NM N+2? again sorry for being a nuisance.
SMIC will get a unit of the SMEE 28nm DUVL early next year for verification and testing.
Their 28nm FAB which is huge, is currently under construction.
Possibly production will start late next year if they can finish construction of the FAB and also finish verification of the DUVL by then.

I wouldn't put much stock on 45nm using 90nm scanner with double patterning. I mean it is not impossible but is it economically viable?
Unless someone already developed this technology for other purposes and Huawei is riding on that. Which might be the case.

The major difference is they allegedly use a different light source. Instead of ArF they use KrF light source which only allows lower resolution details to be written. It is older generation technology from the late 1990s.

Just think about it. You wait a single year and you have immersion lithography tools from SMEE which are much more advanced and might scale all the way to 7nm with upgrades. It does not make sense to make a major investment into these tools. But it is a way to get their feet wet so to speak.
SMEE is currently mass producing a 65nm Dry Lithograph. This is probably what Huawei is using for their 45nm process.

SMIC will do well in 2021 to 2022, because of tightness and shortage of wafer capacity, even in 8 inch wafer an old tech is having problem meeting demand. What is scary is that TSMC will mass produce their 3nm in 2022 ahead by a year, they had monopolized the 7nm and 5nm production, with SAMSUNG having problem with their 7nm and 5nm production and yield. I think SMIC will have an opportunity if they will able to mass produce it's 7nm N+2 chips , with strong demand and limited supply,(as of now only 2 FABS produce the 7nm chips) it will snap up immediately.

Oh. Any ideas why SMIC not buying such equipments. Are there any excuse s? Its 45nm/55nm is it's biggest revenue earner.

The 90/45nm is the sweet spot of low volume ICs.

Not so much speed/power consumption difference compared to 7nm, only issue is the die bigger, but it makes easier to dissipate the heat.

Big difference is it so cheap to make new ICs on 90/45nm,makes it easier to iterate to usable chip designs.

And multiple patterning is the only way to go for low nm, means if there is a 90% yield on 90nm, then with 5 mask it will be 53%.

SMIC has always used ASML and American Equipment as it has clients overseas with various specifications and it has claimed before that verification costs of local equipment is expensive and time consuming. Also the influence of Taiwanese Managers and Liang Mongsong play a part.
Things have changed with the sanctions and we will see them get SMEE products and help with the verification.
