Innoscience Semiconductor Makes Landmark Listing on HKEX

On December 30, 2024, Innoscience Semiconductor (Suzhou) Co., Ltd. (stock code: 02577.HK) officially went public on the Main Board of the Hong Kong Stock Exchange. The company issued 45.364 million H-shares at an offering price of HKD 30.86 per share, raising funds primarily to expand gallium nitride (GaN) production capacity, product portfolio, and application research.

Market Leadership in GaN Power Semiconductors

Founded in 2017, Innoscience specializes in third-generation semiconductor GaN chip R&D and manufacturing. Its product portfolio includes discrete devices, integrated circuits, wafers, and modules. By the end of 2023, the company had captured a 42.4% global market share in GaN power semiconductors, ranking first worldwide in terms of GaN discrete device shipment volume.

Why Gallium Nitride?

GaN is a key material in third-generation semiconductors, offering several advantages over silicon and other materials:

High-frequency performance

High electron mobility

Low on-resistance

Zero reverse recovery loss

These features enable higher energy efficiency, reduced energy loss, and smaller device sizes, making GaN power semiconductor chips indispensable for applications requiring high efficiency and compactness.

Innovations in GaN Manufacturing

Innoscience has been at the forefront of GaN manufacturing, leveraging 8-inch silicon-based GaN wafers (GaN-on-Si) to reduce production costs and improve efficiency. The company's early investment in 8-inch technology has given it a competitive edge over peers still focused on 6-inch production.

2017: Established the first complete 8-inch GaN-on-Si wafer and power device production line in Zhuhai, China.

2021: Opened the world's largest 8-inch GaN-on-Si wafer manufacturing facility in Suzhou.

According to its prospectus, Innoscience is the first company globally to achieve mass production of 8-inch GaN-on-Si wafers, with:

An 80% increase in wafer yield per chip

A 30% reduction in unit chip cost

A yield rate exceeding 95%

Expanding Capacity to Meet Market Demand

In the first half of 2024, Innoscience's total GaN wafer production capacity reached 73,000 wafers annually, with:

Suzhou base: 49,000 wafers/year at 71.8% utilization

Zhuhai base: 24,000 wafers/year at 74.8% utilization

Proceeds from the IPO will support:

60%: Expansion of 8-inch GaN wafer production, equipment upgrades, and workforce hiring.

20%: R&D and product portfolio expansion to penetrate end markets like consumer electronics, renewable energy, industrial applications, automotive electronics, and data centers.

Market Potential for GaN Power Semiconductors

The global market for GaN power components was valued at $271 million in 2023 and is projected to reach $4.376 billion by 2030, with a CAGR of 49%. Notably, non-consumer applications (e.g., automotive, data centers, motor drives) are expected to grow from 23% market share in 2023 to 48% by 2030.

Conclusion

Innoscience Semiconductor's listing marks a significant milestone in the GaN semiconductor industry, showcasing the company's technological leadership and market dominance. With its advanced 8-inch production capabilities and plans to expand further, Innoscience is well-positioned to capitalize on the growing demand for GaN solutions across diverse applications.
