Grand Opening Ceremony of SJSemi's J2B Fab: First Batch of Domestic Equipments Fuels Expansion of 3D Multi-Die Integration Packaging Project

JIANGYIN,China,July 20,2023 --On July 20,2023,SJ Semiconductor (Jiangyin) Co. ("SJSemi") held a ceremony for the move-in of the first batch of productionequipmentsin its newly built J2B plant. This marks the timely completion and operation of the Phase II manufacturing expansion project at SJSemi's Jiangyin production base,as well as the steady progress of its 3D Multi-Die integration packaging project with a total investment of 1.2 billion US dollars,ushering in a new stage of development.

The first batch of equipments moved in covers the main process steps for advanced wafer-level packaging,including exposure,development,electroplating,cleaning,plasma sputtering,thinning and polishing,testing and measurement. It is worth mentioning that the equipment for SJSemi's initial 12-inch mid-end bumping production line in 2015 was entirely sourced from overseas suppliers. However,the first batch of tools for the 3D Multi-Die integration packaging line solely comes from domestic equipment manufacturers.

Adhering to the principles of maintaining the technology leadership,ensuring first-class product quality,and providing excellent manufacturing services,SJSemi works closely with its supply chain partners,continuously improving supply chain diversity to enhance the resilience of its high-performance Multi-Die integration packaging business. This enables SJSemi to better meet the long-term visible,stable,and reliable service requirements of its global customers.

The move-in of the first batch of equipments signifies the official delivery and operation of the J2B plant,effectively ensuring the company's capacity expansion and further technological innovation and development. "We will actively collaborate with domestic suppliers and continue to open up procurement of overseas equipment,ensuring supply chain security and striving to provide reliable and satisfying services to global customers." said Mr. Cui Dong,Chairman and CEO of SJSemi.
