Looks like some consolidation in China IC industry..

Goodix Technologies issued an announcement stating that it has terminated the acquisition of Yunying Valley.


Shenzhen Goodix Technology Co., Ltd. held the fifth meeting of the fifth board of directors and the fifth meeting of the fifth board of supervisors on March 3, 2025, and reviewed and approved the "Proposal on Termination of Issuance of Shares and Payment of Cash to Purchase Assets and Raise Matching Funds", agreeing that the company will terminate the issuance of shares and payment of cash to purchase assets and raise matching funds, and authorize the company's management to handle matters related to this termination. The relevant matters are now announced as follows:

The company intends to purchase 100% of the shares of Yunyinggu Technology Co., Ltd. by issuing shares and paying cash. At the same time, the company intends to issue shares to raise supporting funds (hereinafter referred to as the "Transaction"). This transaction is not expected to constitute a major asset reorganization as stipulated in the "Management Measures for Major Asset Restructuring of Listed Companies", but it involves issuing shares to purchase assets. This transaction will not result in a change in the actual controller of the company.

Carbon nanotubes make important progress in display technology​


Peking University Shanxi Carbon-based Thin Film Electronics Research Institute R&D team and Chengdu Chenxian Optoelectronics Co., Ltd. have achieved comprehensive optimization of performance indicators for display driver applications by optimizing the gate dielectric layer and passivation layer of CNT TFTs. Using HfO 2 /SiO 2 stack as gate dielectric and HfO 2 /SiO 2 stack as passivation layer, CNT TFTs with 10 μm channel length have an average I on of 1.2 μA/μm, and when V ds is -0.1 V, I on /I off exceeds 10 6 and 10 5 at V ds of -0.1 V and -4.1 V , respectively, SS is as low as 180 mV/dec, V hyst is as low as 0.5 V, and there is almost no bipolarity; the average I on of 2 μm channel length devices reaches 16.4 μA/μm, representing the best overall performance of CNT TFTs with micron-scale channel length. Based on these optimized CNT TFTs, effective modulation of micro-LED pixels has been successfully demonstrated.

Compared with Kirin 9020, the main frequency of the super core of Kirin 9020A is reduced by 100Mhz, and the main frequency of the small core is also reduced by about 150Mhz. The overall performance gap is about 5%. For ordinary consumers, there is no obvious difference in daily use. Of course, there may be other versions of Kirin 9020 in the future...

China leads in basic research on next-generation semiconductors, producing more than twice as many papers as the United States

US agencies have analyzed that China is leading in basic research to support the next generation of computers. If these studies are commercialized, some people are worried that export controls imposed by the United States to maintain its advantage in semiconductor design and production may become ineffective.

The Georgetown University Emerging Technology Observatory (ETO) research team released their findings on March 3, analyzing semiconductor design and manufacturing-related papers published worldwide from 2018 to 2023. The research team expanded the scope to include new semiconductor architectures (design methods) as well as existing computer chips and artificial intelligence (Al) optimized graphics processing units (GPUs), using Al machine learning algorithms to analyze research trends.

The number of papers including Chinese researchers is 160,852, more than twice that of the United States (71,688). India (39,709), Japan (34,401) and South Korea (28,345) follow closely behind. It is worth noting that from 2018 to 2023, the growth rate of semiconductor-related papers in China reached 41%, much higher than India (26%), the United States (17%) and South Korea (6%).

China not only excels in the number of papers, but also in research influence. Among the top 10% of the most cited papers, Chinese researchers wrote 23,520 papers, accounting for nearly half of the total. It was followed by the United States (10,300 papers), South Korea (3,920 papers), Germany (2,716 papers) and India (2,706 papers).

Nature sub-journal! National University of Defense Technology has made important breakthroughs in the field of optical computational imaging

Recently, a team from the School of Science at the National University of Defense Technology has made an important breakthrough in the field of optical computational imaging research. The researchers have successfully developed a new optical imaging method called "relay-projection microscopic telescopy (rPMT), which is expected to solve the bottleneck problem that has long restricted the development of optical imaging technology. The research results were published in the top international journal "Light: Science & Applications (Light: Science & Applications, impact factor 20.6) under the title "Relay-projection microscopic telescopy".

Under current technical methods, how to simultaneously improve the spatial resolution, imaging distance, and depth of field of optical imaging systems is a recognized bottleneck problem in the field of optical imaging. In fields such as biomedical research, semiconductor manufacturing, and remote diagnosis, there is an increasing demand for improvements in these performance parameters, but existing solutions can often only seek compromises between these three parameters and cannot achieve simultaneous improvements. To meet this challenge, researchers first proposed the rPMT method, which subverted traditional optical imaging methods through a unique square-law relay projection mechanism and non-line-of-sight light collection strategy, achieving a perfect fusion of microscopy and telephoto functions.
