Chinese semiconductor industry

Jiangsu Jingchuang Advanced Electronic Technology Co., Ltd. has been focusing on the fields of high-precision precision, grinding, and polishing technologies for many years, and is committed to providing advanced independent, serialized, and intelligent semiconductor domestic equipment and supporting process integration solutions to accelerate the advancement of the industry The localization process helps the development of my country's semiconductor industry. After ten years of unremitting development, the company has developed into a high-tech enterprise with a digital R&D innovation center, a standard industrialized production base of tens of thousands of square meters, a joint development laboratory for advanced semiconductor manufacturing processes, and a complete high-level professional talent team. . Unikerui is a wholly-owned subsidiary of Jiangsu Jingchuang Advanced Electronic Technology Co., Ltd. It aims to build a research and development center in Xiangcheng Economic Development Zone and establish a new and higher-standard purification process and testing workshop, constant temperature production workshop, and new product assembly workshop.

Fuyang Intelligent Manufacturing Industrial Park is located at the intersection of Fuyuan Road and Chengyun Road in Xiangcheng Economic Development Zone, covering an area of 96.3 mu. There are 12 factories in the park with a construction area of 52,000 square meters. In recent years, Fuyang Intelligent Manufacturing Industrial Park has successfully attracted Suzhou Hale Intelligent Equipment Co., Ltd., Suzhou Caroy Precision Tool Co., Ltd., Shengying Semiconductor Equipment (Jiangsu) Co., Ltd., Suzhou Silicon Vision Technology Co., Ltd., Quanchuan Technology (Suzhou ) Co., Ltd., Suzhou Unicore Semiconductor Technology Co., Ltd., Wonder New Materials (Suzhou) Co., Ltd., Wistan (Suzhou) Intelligent Technology Co., Ltd. and many other high-quality enterprises have settled in.

At present, with the opening of the R&D center and high-standard production workshop of Suzhou Unicore Semiconductor Technology Co., Ltd., the transformation and innovation park of Fuyang Intelligent Manufacturing Industrial Park with intelligent manufacturing as the main body and semiconductor industry as the characteristic has begun to take shape. With the semiconductor industry and intelligent manufacturing as the key development direction, the park will be further built into a highland of specialized and special new industries in the Economic Development Zone and a gathering area for companies to be listed on the Science and Technology Innovation Board.

Recently, DATE 2023 (European Conference on Design Automation and Testing), a well-known conference in the EDA field, was held in Antwerp, Belgium. Research results and conducted in-depth exchanges. In this conference, Peking University won the Best Paper Award for its achievement on the layout automatic routing of analog integrated circuits .
Compared with digital integrated circuits, the automation degree of analog integrated circuit design is lower, especially the layout has long relied on manual drawing. Among them, wiring needs to complete the interconnection between pins, which is an extremely cumbersome step in layout design, and the wiring result has a great impact on the post-simulation performance of the analog circuit. Analog circuit layout not only needs to consider complex geometric constraints, such as satisfying various design rules, reducing winding bending, etc., but also needs to consider constraints related to electrical performance, such as electromigration, voltage drop, and symmetry. How to efficiently explore wiring schemes and reduce manual intervention under various complex constraints is an urgent problem to be solved in the automatic wiring of analog circuits.
The team of researcher Lin Yibo and Professor Wang Runsheng from the Department of Design Automation and Computing Systems/Integrated Circuit Advanced Innovation Center of the School of Integrated Circuits, together with teachers and students from the Department of Integrated Circuit Design, proposed a multi-constraint collaborative analog circuit layout automatic wiring framework, and realized The tool prototype SAGERoute can simultaneously consider complex geometric and electrical constraints, automatically solve the interconnection line width that meets the constraints, plan the wiring topology and complete the connection. The wiring tool has been verified on multiple real tape-out cases, including manually drawn and laid out FIA and SAR-ADC circuits, covering three process nodes of 65nm, 40nm and 28nm, and can complete the wiring within tens of seconds. And achieve the post-simulation performance close to the manual wiring of design experts.
This work was published under the title "SAGERoute: Synergistic Analog Routing Considering Geometric and Electrical Constraints with Manual Design Compatibility", doctoral students Zhang Haoyi and Gao Xiaohan are the co-first authors.​

On April 21, Jintuo shares stated on the interactive platform that the company is committed to tackling some semiconductor equipment with technical barriers and domestic blanks in the packaging and testing links and silicon wafer manufacturing links. At present, it has developed semiconductor chip packaging furnaces, Wafer Bumping welding equipment, Vacuum formic acid welding equipment, gluing machine, nitrogen oven, dust-free pressure oven and other equipment products. In the future, the company will continue to promote technology extension and product upgrades, and broaden the application in manufacturing fields such as IGBT, IC substrate, Wafer Bumping, Clip Bonding, FCBGA, etc. Based on high-quality imported replacement equipment products, it will contribute to the independent and controllable promotion of the semiconductor industry chain strength.
