KingSemi: A grand ceremony was held to celebrate the delivery of the 2000th KingSemi device​

In early summer, flowers are blooming and plants are flourishing. On May 11, colorful flags were flying in the Caiyun Road factory of Xinyuan Micro, and the atmosphere was full of joy. All employees participated in the ceremony and witnessed the unforgettable moment when the 2000th Xinyuan Micro device was shipped out of the factory!

The celebration ceremony kicked off with the chorus of Xinyuan's micro-company song "Responsible for Victory". Creating value for customers is Xinyuan's mission. Xinyuan people always uphold the corporate spirit of being responsible for victory, keep our original aspirations in mind, and pursue common beliefs.

Zong Runfu, Chairman and President of Xinyuan Micro, delivered a speech at the shipping ceremony. Zong said that it took us 9 years from the first equipment to the 100th equipment shipped. From the 1900th to the 2000th, it took us less than 4 months! This means that Xinyuan's equipment has crossed the difficult exploration stage and is moving forward at a high speed on the fast track of mass production. The 2000 equipment we have produced has achieved full coverage of domestic mainstream process nodes and shines in domestic mainstream FAB factories. We must continue to research and develop, continue to launch market-competitive products, and create value for customers!

Huazhong University of Science and Technology and Shanghai Institute of Optics and Fine Mechanics jointly held a research project seminar on EUV lithography light source research​


Tang Ming, deputy dean of the School of Optics and Electronic Information of Huazhong University of Science and Technology, Zhang Jinwei, assistant to the dean, and six other tutor representatives recently went to Shanghai to jointly hold a research project seminar and joint training cooperation exchange meeting with the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences. Leng Yuxin, deputy director of the Shanghai Institute of Optics and Fine Mechanics, as well as tutor representatives from both sides and 15 joint training students attended the meeting. The meeting was chaired by Jin Lihui, deputy director of the Graduate School of the Shanghai Institute of Optics and Fine Mechanics.

In the scientific research exchange session, Lin Nan, deputy director of the National Key Laboratory of Ultra-Strong Laser Science and Technology of Shanghai Institute of Optics and Fine Mechanics, gave a report entitled "Research Progress of Extreme Ultraviolet Lithography Light Source"; Li Sikun, Party Secretary of the Information Optics and Optoelectronic Technology Laboratory, gave a report entitled "Simulation and Detection Technology for Lithography Applications"; Shi Zhiyong, engineer of the National Key Laboratory of Ultra-Strong Laser Science and Technology, gave a report entitled "Research Progress of Theoretical Simulation of LPP-EUV Lithography Light Source"; Professor Li Zhengyan of the School of Optoelectronics gave a report entitled "Laser Plasma Diagnosis and Droplet Tin Target"; Professor Zhu Guangzhi gave a report entitled "High-Power and High-Energy Solid Picosecond Ultrafast Laser"; Associate Professor Li Bo gave a report entitled "Key Technologies of High-Power Pulsed CO2 Lasers". The teachers present actively discussed their respective scientific research fields and cutting-edge progress, sparked innovative wisdom from the exchanges, and found opportunities for win-win cooperation from the exploration.

In the subsequent HUST joint training teacher-student exchange session, Mr. Tang Ming, on behalf of the college leaders and teachers, greeted the students and encouraged them to make good use of the educational and scientific research resources of both sides, seize opportunities, improve their abilities, and take on responsibilities in the Shanghai Institute of Optics and Fine Mechanics. The joint training students said that the topics during the joint training were closely centered on major national projects and needs, and they deeply felt the strong scientific research atmosphere in the institute, and carried out experimental research on the high-tech scientific research platform. They will cherish the opportunity and work hard to achieve good results.​

Explore HiSilicon's Hi1105-GFCV100 module and its manufacturing journey between TSMC and HLMC foundries, highlighting the design consistency and adaptability in the semiconductor industry amidst global chip shortages.

HiSilicon's

is a versatile Wi-Fi/BT/GNSS combo module integrated into Huawei smartphones from 2020 to 2023. Supporting 802.11ax (Wi-Fi 6 only), Bluetooth 5.2, and comprehensive GNSS operations, this module provided non-cellular connectivity and geo-location capabilities. Despite technological advancements, the module remained a Wi-Fi 6 only component until its evolution in the Hi1105GFCV120 with NearLink capabilities in the Huawei Mate 60 Pro.

The global semiconductor shortage, affecting various electronic products, prompted foundries to expand their capacity at mature nodes, notably 28 nm. SMIC has been a primary Chinese foundry with a high-k metal gate (HKMG) 28 nm process, serving high-volume clients like HiSilicon since 2016.
