so this is basically CXMT also demonstrating 3D DRAM designs I guess. Makes sense since hvpc mentioned that aside from Huawei, CXMT and YMTC all getting into 3D DRAM
I need to read up on this 2T0C DRAM stuff a little more
For these kind of 3D structures you need ALD equipment tools.
The main equipment of China's first high-energy synchrotron radiation light source storage ring is installed with a closed loop, emitting light 1 trillion times brighter than the sun..

It can be transported to the storage ring tunnel for installation. Depending on the number of unit magnets, each pre-alignment unit weighs about 1.7 to 8.5 tons. The installation team faced difficulties such as heavy equipment, dense tunnel equipment, and failure to affect the pre-alignment accuracy. In order to better complete the installation task, the team designed and customized a special Crane trucks and tooling, organizing process installation experiments, optimizing transportation plans, checking equipment interfaces, installation and operation spaces, and finally confirming batch installation plans, laying the foundation for efficient advancement of storage ring tunnel installation. Since the beginning of February this year, the storage ring has started to install tunnel equipment. All systems have worked closely together to dynamically adjust the installation plan according to the equipment development progress. It took 10 months to complete the entire ring with 288 pre-alignment units, 240 bent two-pole magnets, 288 Installation of main equipment such as a base to achieve a closed loop of main equipment installation.
HEPS is a major national science and technology infrastructure project approved by the National Development and Reform Commission and constructed by the Institute of High Energy Physics, Chinese Academy of Sciences. It is the core device of Beijing Huairou Science City. After completion, It will become my country's first high-energy synchrotron radiation light source, and one of the brightest fourth-generation synchrotron radiation light sources in the world, which can emit light brighter than the sun. 1 trillion times of light,helps to analyze the microstructure and evolution mechanism of matter in a deeper level, for improvement my country's national development strategy and original innovation capabilities in the field of cutting-edge basic science and technology provide a high-tech research platform.
With the development of semiconductors, Shenzhen Longtu photomask rushes to the market.

Using AI and a recognition rate of 90%, this SiC equipment company has achieved a new breakthrough!
On December 12, the official Weibo of Dalian Chuangrui Spectrum Technology Co., Ltd. (hereinafter referred to as " Chuangrui Spectrum ") stated that the company has recently achieved a breakthrough in non-destructive optical detection technology for dislocation defects in silicon carbide (SiC) substrate wafers. progress , and will simultaneously launch special equipment for non-destructive testing of dislocations on SiC substrate wafers: SIC-SUB-9900 .
According to reports, the equipment is based on the principles of transient excitation and scattering spectroscopy and uses large-area optical imaging to achieve high-speed, accurate, non-contact, non-destructive optical detection of dislocation defects in SiC substrate wafers. Combined with AI recognition, it can accurately identify and classify BPD, TSD, TED and other defects in the substrate wafer (using the results of the alkali etching method widely used in the industry as a reference, the identification accuracy reaches more than 90%) .
Compared with the existing XRT (X-ray topography analysis) technology, this detection technology has significant advantages such as simple operation, fast detection speed, and high cost performance. Compared with the point scanning mode in nonlinear optical inspection, the large-area imaging method used in this equipment greatly improves the inspection speed: taking a 6-inch wafer sample as an example, the fastest inspection time is less than 17 minutes!
The number and distribution of dislocation defects such as BPD, TSD, and TED in SiC substrate wafers are important parameters that reflect the quality of the substrate. Dislocation defects in the substrate can further extend into the epitaxial layer, having a huge impact on the quality of the epitaxial layer and the final chip yield. Therefore, accurate detection, identification and statistics of dislocation defects in the substrate are extremely important aspects in substrate wafer production.
It is understood that Chuangrui Spectroscopy was founded in 2016. Based on independent technology, it has deeply cultivated the two major application fields of scientific instruments and semiconductor material testing, and has realized the empowerment of the entire industry chain from basic research to industrial production.
In March this year, Atheros Spectrum's SiC wafer quality large-area imaging system SiC-MAPPING532 reached the standard of sustained and stable operation and was officially shipped offline to well-known customers in the industry. This equipment is the world's first third-generation semiconductor defect detection equipment based on transient spectroscopy technology . It not only achieves fully independent domestic substitution of related technologies, but also comprehensively surpasses imported similar products in various technical indicators.
What is this? Looks a bit weird since its only 1 core. Could be a new chip with broken geekbench results or someone trolling?
Well says 8 threads.
