[News] XMC Initiates IPO Plan, Potentially Becoming China’s First HBM Foundry

2024-05-15 Semiconductors editor

NOR Flash manufacturer Wuhan Xinxin Semiconductor Manufacturing Co. (XMC) recently disclosed an IPO counseling filing with the Hubei Securities Regulatory Bureau, according to the official website of the China Securities Regulatory Commission. Its recently announced bidding project may indicate its ambition to become China’s first HBM foundry, according to the report by Chinese media Semi Insights.

As per information from its website, XMC provides 12-inch foundry services for NOR Flash, CIS, and Logic applications with processes of 40 nanometers and above. Originally a wholly-owned subsidiary of Yangtze Memory Technologies (YMTC), XMC announced in March its first external financing round, increasing its registered capital from approximately CNY 5.782 billion to about CNY 8.479 billion. Its IPO counseling filing also indicates that it is still majority-owned by YMTC, with a shareholding ratio of 68.1937%.

According to market sources cited in the same report, XMC’s initiation of external financing and IPO plan is primarily aimed at supporting the significant expansion during a crucial development phase for YMTC. Given the substantial scale of YMTC, completing an IPO within three years poses challenges. Therefore, XMC was chosen as the IPO entity to enhance financing channels.

It is noteworthy that XMC also announced its latest bidding project on HBM (High Bandwidth Memory) – related advanced packaging technology R&D and production line construction, according to local media.

The project indicates the company’s capability to apply three-dimensional integrated multi-wafer stacking technology to develop domestically produced HBM products with higher capacity, greater bandwidth, lower power consumption, and higher production efficiency. With plans to add 16 sets of equipment, XMC’s latest project aims to achieve a monthly output capacity of over 3000 wafers (12 inches), showing its ambition of becoming China’s first HBM foundry.

On December 3, 2018, XMC announced the successful development of its three-dimensional wafer stacking technology based on its three-dimensional integration technology platform. This marks a significant advancement for the company in the field of three-dimensional integration technology, enabling higher density and more complex chip integration.

Currently, XMC has made much progress in the research and development of three-dimensional integrated multi-wafer stacking technology, which has been evident in the successful development of three-wafer stacking technology, the application of three-dimensional integration technology in back-illuminated image sensors, advancements in HBM technology research and industrialization efforts, as well as breakthroughs in the 3D NAND project.
