Shanghai Microelectronics plans a domestic IPO and is expected to deliver the first SSA/800-10W lithography equipment by the end of the year

According to CITIC Construction Investment,Shanghai Microelectronics Equipment (Group) Co., Ltd. plans to conduct a domestic initial public offering (IPO) and go public, CITIC Construction Investment is its coaching institution. According to official information, Shanghai Microelectronics was registered and established on March 7, 2002. It is mainly committed to the development, design, manufacturing, sales and technical services of semiconductor equipment, pan-semiconductor equipment, and high-end intelligent equipment. The equipment is widely used in integrated circuit front-end, advanced packaging, FPD panels, MEMS, LED, PowerDevices and other manufacturing fields.

Shanghai Microelectronics' lithography machine products mainly include two series.

Among them, the SSX600 series step-scanning projection lithography machine adopts a four-fold magnification projection objective lens, process-adaptive focusing and leveling technology, and high-speed and high-precision self-damping six-degree-of-freedom workpiece stage mask stage technology. It can meet the lithography process requirements for IC front-end manufacturing of 90nm, 110nm, and 280nm critical and non-critical layers, and can be used for large-scale industrial production of 200/300 mm lines.

The SSB500 series stepper projection lithography machine is suitable for rewiring (RDL) of wafer-level packaging, as well as advanced packaging lithography processes such as gold bumps, solder bumps, and copper pillars commonly used in the FlipChip process. It can also meet the TSV lithography process requirements of MEMS and 2.5D/3D packaging through the optional back alignment module.

It was reported in early September this year thatShanghai Microelectronics has made a major breakthrough in the research and development of 28nm immersion lithography machines. It is expected to deliver the first domestic SSA/800-10W lithography machine equipment to the market by the end of 2023.

The largest shareholder of Shanghai Microelectronics is Shanghai Electric Holding Group Co., Ltd., with a shareholding ratio of 34.9099%, and the second largest shareholder is Shanghai Technology Venture Capital Co., Ltd., with a shareholding ratio of 14.4434%.

On September 6 this year, Shanghai Microelectronics underwent industrial and commercial changes.The registered capital was changed from RMB 174,359,934 to RMB 266,124,100, an increase of 52.6%.
