Indeed. Better sell now while you can still make a buck. Soon you may lose the markeshare forever.
And what’s up with all the cope in the comments section?
Honestly the cope is typical fare. A lot of western discourse on Chinese semi deserves to be in the gutter for how lacking it is in quality.
Lithography imports are slowing. Looks like Chinese companies have gotten all they need last year.
Ruishi Technology launches two-dimensional addressable VCSEL chips for lidar and obtains mass production orders ..
With the rapid development of automobile intelligence and autonomous driving technology, the automotive lidar (LiDAR) market has shown rapid growth in recent years. According to Mams Consulting, Ruishi Technology recently launched a new two-dimensional addressable lidar VCSEL chip, which can be applied to smart driving solutions equipped with solid-state lidar to achieve higher-level smart driving functions. At present, this new product has received mass production orders from major lidar manufacturers, and Ruishi Technology has become the first manufacturer in the industry to mass produce two-dimensional addressable VCSEL products.
Two-dimensional addressable VCSEL drives solid-state lidar solutions
As an ideal light source for pure solid-state lidar, two-dimensional addressable VCSEL can achieve the effect of zoned lighting, so that the whole machine does not contain any moving parts, which greatly improves the reliability of lidar and provides solutions for lidar applications. More possibilities. Compared with one-dimensional addressing, two-dimensional addressing requires major adjustments to the epitaxial design, chip process, chip testing and other aspects of the VCSEL chip, and the complexity of the driving scheme is also greatly increased, which has a comprehensive impact on VCSEL manufacturers. Ability is a great test.
Ruishi Technology's two-dimensional addressable area array VCSEL technology supports flexible scanning modes, which can greatly improve energy utilization. Compared with one-dimensional scanning, its power consumption and heat dissipation are more friendly, and it can be dynamically adjusted in real time according to different ranging scenarios. Local transmit power to achieve the optimal energy ratio.
The first 100% domestic supply chain in China
As one of the few manufacturers in the world that can provide two-dimensional addressable VCSEL, Ruishi Technology's two-dimensional addressable VCSEL not only has high-precision and high-reliability sensing capabilities, but also achieved a nationwide supply chain for the first time in the industry. This not only means that Ruishi Technology has achieved independent control in all aspects of chip R&D and production, improving the stability of chip supply, but also greatly reducing chip production and packaging costs.

Xi didn't say bluntly of "doesn't need ASML tells Dutch PM" ... but he did send a clear message something like that ..... Xi is an excellent diplomat, he will never use that kind of language, unlike many in the US
Just media now reporting whatever they feel like it .... very bad quality
A project with an annual output of 30 million silicon nitride substrates and other products was signed in Jiaxing, Zhejiang with a total investment of approximately 5.2 billion yuan
On March 27, a centralized signing ceremony for major projects in the first quarter of Jiaxing National High-tech Zone (Gaozhao Street), Zhejiang Province was held. The vision of Jiaxing National High-tech Zone shows that there are two porcelain semiconductor material headquarters projects with a total investment of more than 5 billion yuan, Mokeda SiC power device and electronic product manufacturing project, and two foreign-invested projects of more than 100 million US dollars, Qiniuyun "China Headquarters" project , Phaeton Intelligent AI intelligent production base project, the signing ceremony was held in two special sessions respectively. The Phaeton Intelligent AI Intelligent Production Base Project plans to build an AI intelligent production base covering smart terminal products such as smartphones, AI robots, and smart wearables. The Cixin Semiconductor Materials Headquarters Project with a total investment of approximately 5.2 billion yuan plans to build an annual production capacity of 30 million silicon nitride substrates and 30 million silicon nitride copper-clad laminates. After the project is put into production, it will effectively fill the gap in the domestic high-end silicon nitride ceramic material industry. , to further improve the automotive power semiconductor industry chain in Jiaxing High-tech Zone and promote Jiaxing Xiuzhou chip industry to become bigger and stronger.
That's why the US is now pushing for ASML and Canon to stop servicing existing machines. They are getting increasingly desperate.
Xingyao Semiconductor launches the first two TF-SAW duplexers in China to meet the high-speed requirements of 5G mobile phones
The vigorous development of global 5G communication technology has greatly increased the demand for radio frequency front-end devices. Under the contradiction between the continuous increase in the number of required chips and the decreasing available layout area, the radio frequency system architecture is constantly updated and iterated. Currently, 5G mobile phones support more EN-DC and DL-CA frequency band combinations to meet users' needs for high speeds. Among them, the EN-DC combination of LB+LB in the B20 and B28F frequency bands is very common.
The two TF-SAW duplexers released by Xingyao Semiconductor this time - B20 Tx & B20+B28F Rx and B28F Tx & B20+B28F Rx, are specially optimized for this application. These two duplexers are extremely difficult to develop due to their wide bandwidth and extremely small spacing between transmission and reception. They have always been extremely scarce products in China. Two duplexers are used together to support B20+B28F EN-DC, which can effectively adapt to the high-cost Phase7 LE solution and save an antenna for the system.
Changxin Technology raised 10.8 billion yuan! Increased funding to boost DRAM business, with valuation reaching 140 billion yuan
According to news on March 29, Changxin Technology , which has attracted much attention in the industry because of its wholly-owned subsidiary Changxin Storage , has a total financing scale of 10.8 billion yuan in its latest round, with a pre-investment valuation of approximately 140 billion yuan.
Among them, GigaDevice plans to invest 1.5 billion yuan in a strategic capital increase. After completion, it will directly hold approximately 1.88% of the equity of Changxin Technology. Zhu Yiming, the actual controller and chairman of GigaDevice Innovation, is also the chairman of Changxin Technology.
Currently, GigaDevice is cooperating with Changxin Memory in DRAM product procurement and foundry services, and is developing self-developed GigaDevice brand DRAM business, focusing on niche DRAM products.
AMEC SD-RIE tool is on verification and has develop a High Power 400KHZ RF matching source
In terms of logic chips, SD-RIE has carried out on-site verification at leading domestic logic chip manufacturing customers. At the same time, the company has also reached on-site evaluation intentions with a number of logic chip manufacturing customers; after successful verification, the company will achieve full coverage of the CCP etching process for logic chips. In terms of memory chips, in response to the demand for ultra-high aspect ratio etching, the company is actively deploying ultra-low temperature etching technology. At the same time, the self-developed high-power 400kHz bias RF UD-RIE has been verified in the production line to have an etching depth of ≥60:1. wide-ratio structure capabilities.
