Guangliwei (Semitronix): In the WAT test, the company's products have achieved high-quality domestic substitution
Jiwei.com news, recently, Guangliwei said in an institutional survey that the WAT testing machine is one of the necessary equipment for integrated circuit manufacturing. The company's WAT testing equipment has only begun to scale into the new fab in the past two years. Production line. Compared with EDA software, the company's WAT test equipment has the characteristics of higher unit price and relatively short promotion period after verification. 20 units sold.
In the past two years, with the increase in the demand for localization of integrated circuits, especially the necessity of the chip self-sufficiency rate, the "wave of factory construction" in domestic fabs will greatly promote the market demand for WAT testers and promote the company's business of this type. rapid growth. The company's WAT test equipment was initially developed to cooperate with the design of EDA software, and the gradual breakthrough of test accuracy and speed achieved by gradual technical iteration in the later stage is the result of enterprise innovation. At present, in the WAT test link, the company's products have achieved high-quality domestic substitution, so it can support the development of the national integrated circuit industry from point to point in this field.
Guangliwei said that the company has continued to develop in the field of integrated circuit yield for more than ten years. The relevant EDA software is mainly used to design various test chips, and to achieve the yield by conducting electrical parameter testing and data analysis on the test chips after tape-out. purpose of promotion. Customers can use the company's EDA design software to achieve more efficient design of test chips and test structures, and at the same time combine various addressable circuit IP technologies to achieve more than 10 times the area utilization of test chips. The design solutions of conventional test chips, addressable test chips, high-density test chips and product-based test chips provided by the company are widely used in first-class integrated circuit manufacturing and design companies at home and abroad. The process node covers 180nm ~ 3nm, helping integrated circuits from Improve chip performance, yield and stability throughout the product cycle from design to mass production.
Guangliwei said that the company's yield improvement method is based on efficient electrical testing. Therefore, the company's product line has been continuously enriched and expanded around electrical testing techniques and methods, solving the three major links of test object design, testing and data analysis. The problem has formed a business closed loop with improved yield.
First of all, the company started EDA software research and development from the design of the test object, and successfully developed a series of test chip design software, especially the company's addressable test chip, its innovative circuit IP and the placement and winding technology between test structures , the number of test structures in the same area is increased by ten to dozens of times, and the large increase in the number of test structures puts forward higher requirements for the test efficiency of the test equipment. Therefore, not solving the test efficiency problem will lead to EDA software. The advantages of the designed design scheme cannot be effectively brought into play.
Based on the above pain points, in order to solve the test efficiency problem brought by more test requirements of customers, the company has been developing wafer-level fast electrical testing machines since 2010, supporting the company's EDA software design scheme, and selling the equipment as a research and development machine to Used by R&D departments of first-class fabs at home and abroad.
Since then, after nearly ten years of iterative R&D and technological breakthroughs, the current measurement accuracy has reached the high-precision standard below pA level, realizing the upgrade and transformation from R&D machines to mass production machines, making the product application breadth from the R&D link. Extend the application to mass production. Looking back at the development history of the company's WAT test equipment, it can be seen that the WAT test equipment is closely related to the yield improvement field where the company is located, and is a part of the company's yield improvement technology and product ecology. It is in the key link of testing and data source collection, and it is also the company's first product to expand from advanced process development to mass production.
Guangliwei said that the rapid entry of the company's WAT equipment into the mass production line of the fab will highlight the synergistic effect between the company's software and hardware products, and further drive the company's various EDA software to expand from process research and development to broader market space. mass production, thereby driving the growth of the EDA software business.
Guangliwei pointed out that the technical threshold for the development of advanced integrated circuits is relatively high. At this stage, the company's product system combining software and hardware is expanding from advanced process development to mass production line applications, and constantly extending the spatial boundary of the market for yield improvement. In 2019, the company's wafer-level electrical testing equipment first broke the market bottleneck of advanced technology and entered the mass production line, and the market volume of this product expanded dozens of times; in the field of EDA software, the company's EDA software is developing from the advanced technology side. It is gradually applied to the mass production side, and its user base will also extend from the R&D department to the mass production and manufacturing related departments, so as to continue to expand the market application scenarios of EDA software; in 2021, the company's data analysis and management software customer base will enable the company to break through large-scale Wafer factories and high-end design companies have entered into small and medium-sized design companies, and packaging and testing companies and downstream electronics factories have also been included in the company's target user groups, which greatly expands the market space for data software. To sum up, each product line of the company has moved towards a broader mass production line market. In the next two years, the company will take advantage of the original products and technologies to continue research and development in terms of vertical technical depth and horizontal product breadth to create higher The core technical barriers to promote the rapid growth of the company's performance.
