rather interesting one here. Chinese company is investing 200m RMB at a SiC project in Russia. This might be first one of the type i heard.

based on news from last year, this is to produce 42k ton of SiC. 70% for export to China and ASEAN countries

Isn't BYD also a supplier for phonemakers as well? As phonemakers increasingly localise their suppliers, it seems prudent for BYD to expand in that area.

Shanghai Microelectronics’ patent for “projection objective optical system and lithography machine” announced​

According to micronet news , Shanghai Microelectronics Equipment (Group) Co., Ltd. disclosed its latest lithography machine-related patents on November 28. According to Tianyancha, the patent published by Shanghai Microelectronics is called "Projection Objective Optical System and Lithography Machine", and the application publication number is CN117130226A...

The patent abstract shows that the present invention provides a projection objective optical system and a lithography machine. The projection objective optical system includes in order from the object surface to the image surface along its optical axis direction: a first lens group, a second lens group, Diaphragm, third lens group and fourth lens group. Wherein, the third lens group and the second lens group are symmetrical about the aperture, the fourth lens group and the first lens group are symmetrical about the aperture, and the projection objective optical system is symmetrical structure, and all lens groups in the projection objective optical system have positive refractive power, which can increase the field of view size of the exposure system and increase productivity on the basis of improving imaging quality..

I think you are on the right track here.
Audio amp chip is a cheap commodity thing. I think TI is one of the major suppliers.
Why BYD would “waste” time with such a development would be because they probably want to run the fabs at full capacity. They can supply these chips to handset makers and other electronics makers (speakers, etc.) looking to domesticate the supply chain.



I think the biggest danger with printers is honestly just people printing things they shouldn’t or leaving them lying around.

Yida Capital continues to invest in Star Micro Technology to help localize semiconductor equipment parts​

Recently, Yida Capital completed its investment in Wuxi Star Micro Technology Co., Ltd. (hereinafter referred to as "Star Micro Technology"). This is also Yida Capital’s second round of investment in Star Micro Technology since its first investment in 2021.
Star Micro Technology was established in 2015, mainly providing precision motion control products for the semiconductor equipment field; it began the design and development of wafer transfer system products in 2017; it developed and produced the core product of the wafer transfer system, the wafer transfer robotic arm, in 2019; starting in 2020 , the company's precision motion platform and transmission system have been shipped in batches for semiconductor quality inspection, pan-semiconductor precision manufacturing and other equipment.



"Semiconductor equipment is composed of thousands of parts. The performance and accuracy of these parts directly affect the reliability and stability of the equipment. It is also a key factor in upgrading and iterating my country's semiconductor manufacturing capabilities." Director of Star Micro Technology Chang Lu Minjie said that from the beginning, the company has chosen two core products, ultra-precision motion platform and wafer transmission equipment, to help localize the "stuck" semiconductor equipment.
Among them, wafer transfer equipment is used to transfer wafers between various semiconductor equipment. It is an essential and key component of all semiconductor manufacturing processes and testing equipment. Star Micro Technology has now achieved the independence of its core components. As domestic substitution of domestic semiconductor equipment parts accelerates, its advantages over overseas brands after mass production will be highlighted in terms of price, delivery time, and service.
