The construction of the CMP material production base of Boline Semiconductor started​

Zhejiang Boranarun Electronic Materials Co., Ltd. officially broke ground on the construction of the 107-acre Phase II production base located in the high-tech zone of Quzhou Intelligent Manufacturing New City. After the completion of the project, combined with the production capacity of the already operational Phase I project, Boranarun will achieve its goal of deploying 18,000 tons of nano-silicon oxide, 34,000 tons of semiconductor CMP polishing liquid and 1.15 million square meters of polishing pads in Quzhou. It also allows Boranarun to take a step further in its ideal of "becoming a trusted partner in the field of global planarization materials."

Zhejiang Bolainarun Electronic Materials Co., Ltd. focuses on providing overall solutions for planarization materials in the semiconductor industry, and is committed to the technical research and development and industrialization of electronic-grade nano-silicon oxide abrasives, semiconductor CMP polishing liquids, polishing pads and other products, providing overall process material solutions for the nano-level planarization of semiconductor substrates and other materials. Bolainarun's products are widely used in the CMP process of semiconductor wafers such as large silicon wafers, gallium arsenide, silicon carbide, as well as the CMP process of integrated circuits and other fields (such as LED sapphire substrates, consumer electronics and optical metals, glass, etc.). At present, it has established good cooperative relations with well-known companies in the industry such as Jinruihong, Tianke Heda, Shanxi Shuoke and Crystal Optoelectronics.

A novel method for manufacturing a vertical channel 2T0C DRAM based on ALD technology​

Abstract​

Fudan University​

The present invention discloses a manufacturing method of a novel vertical channel 2T0C DRAM based on ALD technology, and relates to the field of computer manufacturing. The present invention utilizes ALD technology to grow high-quality amorphous metal oxide semiconductor thin films, manufactures vertical channel transistors, adopts external gate structures and processes to manufacture 2T0C transistors, and designs a dual-gate structure of a read transistor. The present invention effectively reduces the size of vertical channel transistors by precisely controlling the film thickness, reduces the area and parasitic effects of 2T0C DRAM, and improves integration; the external gate has a more flexible back-end interconnection process layout, and effectively reduces the parasitic effects of transistors when they are working; the dual-gate structure can achieve more flexible read and write operations.

Jingsheng Electromechanical was selected as the second batch of Zhejiang Province's key laboratories.​


Aiming at the major strategic needs of high-quality development of the national integrated circuit industry, the laboratory starts from research goals such as low-defect and high-quality growth process and high-end equipment technology for large-size silicon wafers for integrated circuits. It is committed to solving industry problems such as many defects and low flatness of large-size silicon wafers through key technology research of silicon materials and equipment, building the first domestic 12-inch integrated circuit large silicon wafer equipment experimental line, focusing on research and breakthroughs in key technologies such as crystal growth, grinding, and polishing, establishing an independent and controllable national technology system for silicon material equipment, and building it into a world-class scientific research base with important international influence in the field of semiconductor materials and equipment.

Since CXMT is still 2 generations behind in HBM companies in China will still need to stockpile for a period of time though
US is about to (in about a month or so) put down sanctions preventing South Korea from selling these to China.

With AI bubble crash will it help CXMT close the gap between the leaders?
I’m not sure. If it crashes the investment and speed that the West is moving at will definitely slow but the urgency that China is moving at in regards to AI will definitely slow too. So I guess it really just depends on who still cares the most about AI still after it crashes.

My personal view is that most of this AI crap is completely useless whether in the US or China lol. WSJ says almost a third of the users of ChatGPT are probably high school students cheating on homework and it feels like the whole space has been taken over by grifters.
