Kaishitong delivered the first low-energy, high-beam ion implanter to a new customer in the sensor industry​

On June 13, Shanghai Kaishitong Semiconductor Co., Ltd. (hereinafter referred to as "Kaishitong"), a subsidiary of Wanye Enterprise, successfully delivered the first low-energy large-beam ion implanter to the first new customer in the sensor industry who won the purchase order through bidding. This achievement is not only a reaffirmation of Kaishitong's market competitiveness, but also a sign that Kaishitong has won customer recognition with its independent research and development and customization capabilities, injecting strong momentum into the development of domestic equipment serving the country's major strategies.


As the core interface between the physical world and the digital world, sensors are the foundation for the survival and development of all kinds of modern industries. After a thorough technical comparison, the customer chose Kaishitong. The key consideration was Kaishitong's industrialization capabilities that have been verified in large quantities and its excellent performance in key production lines. At the same time, based on its strong independent research and development and customized service capabilities, Kaishitong machines can better meet customers' personalized process needs and provide strong equipment support for customers' safe mass production.

With the rapid development of the semiconductor industry, Kaishitong will continue to be driven by technological innovation, guided by market demand, and aim at customer satisfaction, constantly improve its core competitiveness, serve customers' high-quality development with excellent equipment solutions, and help the country achieve high-level scientific and technological self-reliance.

Why anyone would need such high refresh rate.
​

Domestic manufacturer SDC plans to launch 720Hz gaming monitor.​

Chinese manufacturer SDC plans to launch a 720Hz WOLED 2K gaming monitor "Lightning 540-Meta", which will be the first to break the 700Hz refresh rate barrier for gaming monitors, with a brightness of up to 335 nits in SDR mode.

If the recent 600Hz gaming monitors from MSI and ASUS aren't fast enough for you, the SDC Optic Soul might just be the one to satisfy your high refresh rate cravings. This isn't your run-of-the-mill 360Hz or 500Hz gaming monitor, but a 720Hz monitor that might be the first to break the 700Hz barrier.

Chinese display manufacturer SDC has reportedly prepared a 720Hz WOLED gaming monitor. Unlike the 600Hz products from MSI and ASUS, it does not use a TN panel, and the current maximum refresh rate of OLED panels is 500Hz. ASUS and MSI have used Samsung's third-generation QD-OLED panels to launch flagship 2K@480Hz QD-OLED gaming monitors, while SDC's 720Hz gaming monitor will use LG's fourth-generation W-OLED panels.

3nm chips and EUV is good and all but next gen semiconductors are going to upgrade defense weaponary.​

​

Shandong University led the team to develop the "Chinese chip", and the domestic radar achieved "detecting the enemy first and defeating the enemy first"​

The National Key Laboratory of Crystal Materials and dean of the Institute of New Generation Semiconductor Materials of Shandong University. He has been forging the future of China's semiconductors in the microscopic world for twenty years.

Faced with long-term foreign technological blockades, "inability to grow, poor growth, and difficulty in processing" have become the three major obstacles in China's silicon carbide materials field, severely restricting the development of China's high-end equipment. The team decided to challenge this "Mount Everest of the semiconductor industry" starting from the most basic theory.

They solved the problem from the nucleation control theory, and innovated the energy level compensation and dislocation composite technology to transform the crystal growth from "blind men groping in the dark" to precise control. After thousands of process optimizations and parameter adjustments, the team finally achieved the leap from 2-inch to 12-inch single crystals - this is not only a simple size breakthrough, but also a disruptive innovation to traditional theories.

The team has conquered more than 40 core patents, formulated my country's first semi-insulating silicon carbide SiC military product standard, and built an independent and controllable technical barrier. What is more valuable is that the team insists on promoting technology implementation with industrial thinking, incubating companies listed on the Science and Technology Innovation Board through technology transfer, allowing "crystals in the laboratory" to move towards large-scale production, and bringing scientific research results out of the school and into society, injecting fresh vitality into the semiconductor industry, and making important contributions to the independent control of my country's key materials technology.

In the field of national defense, breakthroughs in silicon carbide are directly related to national security. The high-purity semi-insulating silicon carbide developed by the team has been successfully applied to the core components of phased array radars, increasing the detection distance by three time., From the J-20's airborne systems to cutting-edge weapons and equipment, this "Chinese core" carries the lifeline of national security. It allows Chinese radars to see farther, missiles to hit more accurately, and laser weapons to be more powerful, becoming an indispensable "hard-core shield" in national defense science and technology.

The breakthrough of silicon carbide is not only related to national defense, but also brings about changes in new energy and other fields. Facing the new energy industry, the team has made breakthroughs in the core technology of n-type silicon carbide manufacturing, providing underlying support for electric vehicles to solve the "range anxiety" and "charging bottleneck". This breakthrough not only helps my country's electric vehicle industry to "change lanes and overtake", but also reshapes the global third-generation semiconductor competition landscape and supports the backbone of China's high-end manufacturing.​

Very interesting that it increased detection distance by 3x. That is quite impressive. With military grade semi-insulating SiC wafer.
