According to the strategic cooperation agreement signed this time, SITWEI and JA Solar will increase their cooperation in process development, product innovation, and capacity supply. In terms of process development, the FSI and BSI process platforms jointly developed by STMicroelectronics and JA Solar have entered the mass production stage, and the new 55nm Stack process platform will also achieve mass production this year. In the future, the R&D teams of both parties will continue to work closely together, deeply integrate advantageous resources, and jointly promote the domestic CIS process to reach new heights. In terms of product innovation, both parties will deeply understand market demand changes and technological trends, jointly develop more high-performance CMOS image sensor products that meet different application scenarios and functions, and provide higher quality and more innovative solutions for downstream application fields.

In this meeting, SITWEI and Jingjiji achieved clear phased goals for production capacity supply. Jinghe Integration will achieve the delivery capability of 15000 stacked wafers per month to SITWEI in the first phase, in order to meet the current production needs of SITWEI's products. With the further increase in market share of SITWEI products, in the second phase, JA Solar will further increase production capacity support and complete the delivery of 45000 stacked wafers per month, providing a solid guarantee for the large-scale production and market expansion of SITWEI's high-end CIS products.

The deepening of this strategic cooperation has profound significance for both companies. With the support of advanced integrated processes and efficient production capacity, SITWEI will further enhance the technological innovation and delivery capabilities of domestic high-end CIS throughout the entire process, ensuring excellent product quality and stable and reliable customer supply services. The deepening technology investment of SITWEI's production and research linkage will also greatly enhance the technical capabilities of crystal integration in the CIS Stacked process, further consolidate its technological advantages and market position in the domestic wafer foundry field, accelerate the technological progress of domestic high-end CIS chips, promote the comprehensive popularization and application of high-performance CIS Stacked technology in a wider range of smartphone models, and promote the application and expansion of CIS Stacked technology in emerging fields such as automotive electronics and machine vision. Taking this signing as an important milestone, in the future, STMicroelectronics and Jinghe Integration will continue to deepen their cultivation of the CMOS image sensor chip industry, deepen their cooperation in production and research technology, continuously improve the technical capabilities and quality of CIS chip products, enhance the domestic supply capacity of high-end CIS chips, and work together to contribute more strength to the development of the domestic semiconductor industry. Both parties will be committed to providing more valuable products and services to global customers, and jointly demonstrate the strength and responsibility of Chinese enterprises in the global semiconductor market.
