Jiejie Microelectronics specializes in R&D, design, production and sales of power semiconductor chips and devices, and forms a business system with chip design and manufacturing as its core competitiveness. The company currently has more than 200 varieties of power semiconductor chips and device products, mainly Used in household appliances, leakage circuit breakers and other civil areas, reactive power compensation devices, power modules and other industrial areas, and communications networks, IT products, automotive electronics and other lightning and anti-static protection areas, to ensure industrial development and residential life The effectiveness, stability and controllability of the use and conversion, and the protection of expensive circuits in emerging electronic products such as automotive electronics and network communications, improve product safety, and become one of the elements of quality assurance for electronic products in emerging markets.
Currently, the design and manufacturing capabilities of power semiconductor chips are the core competitiveness of Jiejie Microelectronics, which is the basis for the company's sustainable profitability and development. The power semiconductor chips of the thyristor series account for more than 60% of the company's operating revenue last year. , The product's profitability is more risky.
Jie Jie Microelectronics disclosed that in recent years, the company has been committed to the expansion of the industrial chain and the transformation and upgrading of its products. It has also focused on R&D projects to increase investment in R&D. As advanced foreign semiconductor manufacturers have more brand-name products and the key Technical reliability and stability, customers have a long period of project approval or argument (replaceable) for new products, and the company may face the risk that the progress of key R&D projects will not be as expected.
