Three transformations of Jiejie Microelectronics

Entering Jiangsu Jiejie Microelectronics Co., Ltd. in Qidong Science and Technology Park, the production lines in the workshop are full of horsepower and busy. In the Qidong Economic Development Zone 4 km away, the company's new power electronic device production line project is also In the construction under fire, the main workshops No. 1 and No. 2 have entered the stage of electromechanical construction.


Jiejie Microelectronics specializes in the R&D, design, production and sales of power semiconductor chips and devices. It mainly adopts the vertical integration (IDM) integrated business model to form a business system with chip design and manufacturing as its core competitiveness. After nearly 20 years of hard work, the company has undergone "three transformations", and the company has taken the top position in the domestic segment of the power semiconductor industry (thyristor).



 

The first transformation of Jiejie Microelectronics began in 1997. At that time, due to the failure to master the core technology, the chips could only be imported from abroad for packaging and sale. Due to the pain of people, the company decided to develop its own chips and focus on the industrialization of semiconductor transistor chips. Jiejie Microelectronics has overcome a series of difficulties such as no technology, no people and no equipment. In 1999, it planned to build a 3-inch chip production line. In 2000, it developed and mass-produced and sold single and bidirectional SCR chips.


After completing the first metamorphosis. In 2006, Jiejie Microelectronics planned to build a thyristor chip (4-inch) production line. In 2018, the yield rate of the 4-inch chips produced by the company reached more than 95%, the key indicators such as product reliability reached the international level, fully equipped with import substitution capabilities, and through annual investment of 5% of R&D investment and technological transformation investment, To ensure that the company has achieved a compound growth rate of more than 20% for several consecutive years.


In 2010, the company developed and mass-produced and sold semiconductor anti-suppression device chips and diode chips; in 2012, it planned to build a thick film and component packaging production line, and mass production and sales in the same year; in 2015, it cooperated with the Institute of Microelectronics of the Chinese Academy of Sciences Co-construction of the "Wide-Band Band Power Electronics Engineering Technology Research Center", which was listed on the Shenzhen Stock Exchange in March 2017, thus achieving the third real change. The company's main product, power semiconductor devices (thyristors), has a domestic substitution 50% market share of imports.


 

Behind the red fire, there are also hidden worries. According to Shen Xinxin, the company's director, secretary of the board and chief financial officer, although Jiejie Microelectronics' thyristor products are leading the same kind of enterprises in China, their indicators and types are fully capable of replacing imports, but their market share in power semiconductors To be improved, there is a certain mismatch between the structure of existing products and the industrial structure. To this end, the company plans to build a MOS business department and a MOS R&D center in December 2017. The company's development plan clearly proposes to strive to build the company into an internationally competitive power (electricity) semiconductor device manufacturer (IDM) and brand operator .


In November 2018, the company's new power electronic device production line construction project officially started construction. The project will invest 550 million yuan in the first phase and build a new power electronic chip production line with an annual output of 600,000 6-inch chips; 5 packaging production lines with an annual output of 3 billion self-sealed power electronic devices, which will form an annual output value of 621 million after production Yuan’s scale, thus comprehensively enhancing the company’s market share in semiconductor power devices.


 "The launch of new projects is another accumulation of the company." Huang Shanbing, chairman of the company, introduced that the company and the Institute of Microelectronics of the Chinese Academy of Sciences jointly established the "Wide Bandgap Power Electronics Engineering Technology Research Center", which mainly researches and develops gallium nitride devices. Cooperate with Xi'an University of Electronic Science and Technology to build a provincial-level "New Power Electronic Device Engineering Technology Research Center", which mainly researches and develops silicon carbide devices; Cooperate with Hunan University to build a "Thousand Person Planning Workstation", which mainly researches and develops fast recovery diode Etc. layout and planning. He said that Jiejie Microelectronics will continue to maintain a high investment in R&D and innovation, insist on quality as its main competitive advantage, and deepen its efforts in the field of power semiconductor devices to achieve high-quality sustainable development.
