Recently, the Department of Industry and Information Technology of Jiangsu Province released the list of "2024 Provincial Enterprise Technology Centers" to be recognized, and the Technology Center of Jiangsu Changjing Technology Co., Ltd. has successfully passed the recognition.
Recently, the Nanjing Daily published a special report on the company's innovative development and accelerated formation of new quality productivity, which comprehensively demonstrated the struggle of Changjing Technology since its establishment, adhering to its original intention, forging ahead, always insisting on research and development innovation and industrial integration, and striving to master key core technologies in the semiconductor field.
As September approaches, the weather gradually cools down, but in the factory of Jiangsu Changjing Technology Co., Ltd., a hot scene appears. With the successful completion of the expansion and upgrading of the first phase of the testing plant, this high-tech company specializing in semiconductor product research and development, production, and sales has reached another milestone in its development process.
As a leading semiconductor power device enterprise in China, Changjing Technology has been rated as one of the "Top Ten Semiconductor Power Device Enterprises in China" by the China Semiconductor Industry Association for five consecutive years since 2019. It has established research and development centers, subsidiaries or offices in many places at home and abroad, with over 20000 product lines and models. It is expected that in the fourth quarter of this year, the first phase of Changjing Technology's packaging and testing base will be fully put into operation, and the localization of power devices will accelerate.
Service Integration - Accelerating the Formation of the Entire Industry Chain
Power semiconductor products are closely related to our lives. From a charger, a smartwatch, to a mobile phone, a LCD flat screen TV, to cars, photovoltaics, and many other large equipment, these electronic products that have been integrated into the "new daily" are ubiquitous.
In fact, high-efficiency power supply, conversion, processing, modulation, and driving all rely on power devices. In other words, wherever there is electricity, there are power semiconductor chips.
In November 2018, with accumulated technology and resources in the field of power semiconductors, Jiangsu Changjing Technology Co., Ltd. chose to establish its headquarters in the Industrial Technology Research and Innovation Park located in Jiangbei New Area, embarking on a "butterfly transformation" journey.
At the beginning of its establishment, the company had only over 30 staff members and was positioned as a semiconductor company with a focus on design. After landing in the new area, on the one hand, it coincided with the "golden period" of independent innovation and domestic substitution in the domestic semiconductor industry. On the other hand, in terms of industrial integration, we also benchmarked international semiconductor giants and actively created a full industry chain ecosystem. At the end of 2020, the company invested in the construction of Changjing Pulian Packaging and Testing Base in Pukou Economic Development Zone, achieving independent and controllable packaging and testing. "The relevant person in charge of Jiangsu Changjing Technology Co., Ltd. introduced," In 2022, the company completed the wafer manufacturing factory acquisition project through industrial mergers and acquisitions, filling the industrial links of power device wafer research and manufacturing
As a result, Changjing Technology, which adheres to the dual wheel drive of "R&D leadership" and "supply chain collaboration" as its development strategy, has formed a full industry chain from chip design, chip manufacturing, packaging and testing to sales.
The evolution from Fabless (fabless) to IDM (vertically integrated manufacturing plant) model cannot be separated from the strong "blood making" ability of the enterprise itself. This independent and controllable entire industry chain, while unleashing strong momentum, is also more resilient and competitive. Nowadays, our products cover several major fields such as consumer, industrial, automotive, and new energy, and our employees have increased to around 1700. The company insists on taking it as its responsibility to independently and controllably develop key semiconductor core technologies. Through continuous research and development innovation and engineering technology optimization in recent years, many products have reached the international mainstream and advanced level in terms of performance and reliability
The first domestically produced substitute for refined "hard technology"
In front of us, a chip the size of a sesame seed is not only the first "hard technology" in China to break the monopoly and complete domestic substitution, but also a representative product for achieving large-scale substitution of imported products in the domestic power device field. Last year, in just six months, it achieved sales of over 100 million yuan.
This product, commonly known as wafer level packaged MOSFET, is a charge and discharge control device that can provide charging protection for lithium batteries, improve the performance and safety of battery systems. Prior to Changjing Technology, only a few companies in the United States and Japan were able to mass produce this product on a large scale.
The small chip did not "emerge", but rather the scientific research and innovation achievements of Changjing Technology through the establishment of a specialized talent team and continuous research and application practice for four years, continuously optimizing and improving the processes related to chips and devices.
This product is mainly used in high-end mobile phones and smart wearable devices, such as placing 4 to 8 chips on mobile phone batteries, which requires making the silicon wafer thinner and smaller in size. At the same time, considering the heat dissipation performance and mechanical strength issues, continuous optimization and improvement of the backing process are also needed, and the yield rate of the chip must be ensured while ensuring that the process meets the requirements. "Relevant R&D personnel of Changjing Technology shared that Changjing Technology's independently developed wafer level packaged MOSFET products have been appraised by the Jiangsu Provincial Department of Industry and Information Technology and are generally at the leading domestic and international advanced level. We are the first in China to achieve mass production and replace imported brands. Currently, we are developing and iterating next-generation technologies to further improve device performance and achieve overtaking in corners.
We have invested a lot of manpower and material resources in this project since 2019. By optimizing our internal R&D system, we have continued to develop and optimize our products and application systems, and strive to promote substitution verification among mainstream customers at home and abroad. Finally, we achieved full substitution and mass production shipment in the second half of last year. The company basically takes three years as a cycle, continuously and rolling out the R&D and substitution of imported high-end device products, constantly launching new products, and achieving incremental breakthroughs. "The person in charge of Changjing Technology said that Changjing Technology has always taken it as its responsibility to achieve independent and controllable key core technologies of power semiconductors in China. Last year, the enterprise was approved to build the" Jiangsu Power Device Engineering Technology Research Center ", which will accelerate the application of semiconductor devices in the mid to high end. Localization substitution in the field.
By promoting industrial innovation through technological innovation, in 2022, Changjing Technology was awarded the national level specialized, refined, and new "Little Giant" enterprise. The "Key Technology Research of Low Power, High Reliability Superjunction MOS Devices" project led by the enterprise was successfully selected as a key research and development plan in Jiangsu Province.
Anchoring High end - Product Application Scenarios' Blooming from Multiple Points'
In recent years, with the rapid development of electric vehicles and new energy applications, IGBT (Insulated Gate Bipolar Transistor) devices and modules, known as "industrial CPUs," have also experienced an explosion. It is expected that by 2025, the size of China's IGBT market will reach 52.2 billion yuan, with a compound annual growth rate of nearly 20%.
As the largest sub category in the entire power device market, IGBT technology has a relatively high threshold and is one of the important products in our medium and long-term planning. Before 2021, there were very few domestic manufacturers, and the localization ratio was very low. Their high reliability design and packaging process control were technical difficulties. Domestic and foreign customers have very high requirements for brand, performance, and reliability when choosing products. ”The market leader of Changjing Technology said that according to the types of IGBT application scenarios, there are mainly three major scenarios: home appliances, industrial control new energy, and automobiles, and one of their cores is to control the rotation of motors.
New quality productivity can promote technological revolutionary breakthroughs, innovative allocation of production factors, and deep transformation and upgrading of industries.
On the basis of continuously improving the process platform, Changjing Technology has developed and launched high-power IGBT single tube and module products, which adopt international advanced processes and have the characteristics of high power density, low loss, low switching stress, high reliability, etc. The performance can benchmark the seventh generation products of international brands, and the relevant parameter performance is systematically optimized for different industry applications. The import substitution advantage is obvious.
Our distinctive feature and advantage lies in our own research and development, self packaging, and gradual creation of full specification coverage from single tube to module. Currently, we have achieved large-scale production in industries such as home appliances, variable frequency servo, photovoltaic energy storage, DC charging piles, and automotive OBC clients. The application of automotive main drive, power transmission and distribution is an important strategic direction for our future layout. ”When it comes to the future, the market leader of Changjing Technology is full of confidence.
Next, Changjing Technology will persistently stimulate creativity, break through key technological barriers in the power semiconductor field, further integrate and stimulate the synergy effect of the entire industry chain, accelerate the research and development innovation of key core technologies and the localization of high-end semiconductor products, closely follow the development needs of the new quality productivity field, cover all scenarios and diversified application markets, strengthen traditional markets, layout emerging markets, and strive to "create a world-class semiconductor brand"
