So what are we looking at here? Life imprisonment or execution?

Maskless lithography is getting a performance boost for industrial applications.

Third-generation semiconductor equipment from device manufacturing to performance characterization​

Geekerwan comes out with his indepth look at the actual performance of Mate 60.

Unsurprisingly, performance of Mate 60 in endurance and heat is really good with the exception of high end gaming (which it struggles)

In terms of battery life on high usage load, it lasts longer than iphone 15 Pro Max

App performance better than Mate 50 or P60 despite using Kirin 9000S vs SD 8+. Reason is that everything is carried by Huawei, so program/chip can be tweaked & optimized to work better with each other. SD8+ was not designed with Harmony OS in mind. Hyperthreading can be optimized so that a core only goes into hyperthreading when application demands it.

so software optimization is important.

i thought @hvpc said D1x is 18 to 19nm? I thought 22nm is their D2y node?

Micron was able to do D1z, D1a & D1b without EUV

It's a tall order, but one of the Chinese fabs (even if not CXMT) should be able to get to D1z without EUVs

Really interesting. this high performing Huawei Micro-pump liquid cooled casing for Mate 60 Pro series has at least chips to provide the power for liquid cooling to circulated. Pretty amazing how much chips are needed for everything

Chinese chip design house UNISOC and leading German testing company Rohde & Schwarz complete the industry’s first IoT NTN RF consistency test case verification


The testing is based on UNISOC’s 5G NTN (non-terrestrial network) satellite communication chip V8821. It signifies a breakthrough in NTN device certification by confirming the suitability of terminals developed based on V8821 for direct satellite connectivity in mobile phones, vehicle-to-vehicle communication scenarios, and integrated terrestrial and satellite IoT scenarios, thus demonstrating strong commercial value, said UNISOC.

Xian Miao, general manager of UNISOC’s Wide-Area IoT Product Division, stated, “UNISOC has been actively engaged in the research and application of integrated terrestrial and satellite technology, achieving outstanding results in standard development, technological research and development, and application validation. Rohde & Schwarz is an important partner of UNISOC. The completion of IoT NTN RF consistency test cases on V8821 is a significant milestone.”

“In the future, the company will continue to collaborate with partners to accelerate the implementation of satellite communication-based IoT, enabling seamless real-time connectivity for all things,” Xian Miao added.

Jin Hailiang, senior director of Products and Systems at Rohde & Schwarz, commented, “Rohde & Schwarz continues to expand its footprint in NTN testing solutions, including functional testing and performance testing, for both private NTN technology and 3GPP NTN technology."

"This successful verification sets an excellent example for NTN device certification and we believe that both parties will engage in more cooperation and validation efforts, providing mature products and testing solutions for the mobile communication and satellite industry,” Jin Hailiang added

With the further integration of ground mobile communication and satellite communication technologies, NTN technology based on the 3GPP R17 standard has emerged as the most prominent candidate for satellite mobile communication. 3GPP R17 defines two NTN technology directions: Narrowband (IoT NTN) and Broadband (NR NTN). IoT NTN, due to its low satellite capability requirements, cost-effectiveness, and versatility, has taken the lead in commercialization.

V8821 boasts high integration advantages, consolidating common communication device functions such as baseband, RF, power management, and storage onto a single-chip platform, according to UNISOC.

Jingrui Electrical Materials plans to acquire a controlling stake in Qianjiang Yihe to open up the upstream and downstream industrial chain of hydrogen peroxide​

Jingrui Electrical Materials announced that the company plans to purchase the shares it holds from Wuhan Haida Chemicals Co., Ltd. ("Wuhan Haida") with 139 million yuan of its own funds or self-raised funds. 55.90% equity of Qianjiang Yihe Chemicals Co., Ltd. ("Qianjiang Yihe"); related party Hubei Changjiang (Qianjiang) Industrial Investment Fund Partnership (Limited Partnership) ("Qianjiang Fund") uses its own funds Or use self-raised funds of 50 million yuan to purchase the 20.08% equity interest in Qianjiang Yihe held by Wuhan Haida. At the same time, Qianjiang Fund increased capital to Qianjiang Yihe with its own funds or self-raised funds of 50 million yuan, and subscribed to Qianjiang Yihe. Jiang Yihe’s new registered capital was RMB 8.0321 million.

Data show that Qianjiang Yihe is one of the earliest companies in China engaged in the research and development of hydrogen peroxide (i.e. hydrogen peroxide). Its main product is industrial-grade hydrogen peroxide, with a production scale of more than 100,000 tons/year. It is one of the company’s core raw materials for high-purity hydrogen peroxide. . Through this transaction, the company has opened up the upstream and downstream industrial chain with Qianjiang Yihe, enriched the company's supply channels for high-purity hydrogen peroxide raw materials, reduced the risk of raw material purchase price fluctuations, and is conducive to improving the company's profitability and competitiveness, and reducing corporate operating risks. .
According to disclosures, all parties agreed that the transaction was valued based on Qianjiang Yihe’s pre-investment valuation of RMB 249 million, that is, the unit price corresponding to each (1) yuan of registered capital was RMB 6.225 (the “transaction unit price”) . After the completion of this transaction, the post-investment valuation of the target company is RMB 299 million.
