The Japanese company Ibiden, headquartered in Ogaki, in the province of Gifu, maintains a prominent position in the global market for substrates for semiconductor packages. Essa company almost exclusively supplies the substrates used in artificial intelligence chips from Nvidia, the world leader in GPUs for AI servers. Demand for these components has grown significantly with the expansion of data centers and generative AI applications.
IC package substrates act as an essential base for connecting the semiconductor chip to the circuit board, ensuring signal transmission, heat dissipation and protection against external impacts. The Ibiden stands out for its advanced technology in flip-chip substrates, which allow greater efficiency and space reduction compared to traditional wire connection methods.
Company history
Ibiden began operations in 1912 as a hydroelectric power generation company. Over the decades, it diversified activities to include production of ceramic materials, printed circuit boards and, from the 1980s, substrates for semiconductor packages.
This transition occurred based on technologies developed in other segments, such as etching of decorative plates. The long-standing partnership with Intel, which began in the 1990s, consolidated the company’s expertise in high-performance substrates for CPUs.
Flip-chip technology
The increasing adoption of the flip-chip method represents an important advance in the semiconductor industry. Nesse process, the chip connects directly to the substrate without using wires, which reduces electrical transmission time and optimizes internal space.
The Ibiden is at the forefront of this technology, producing substrates with multiple layers and precise microviations. Esses components withstand the high heat generated by AI GPUs, such as those in the Blackwell and Nvidia series.
- Flip-chip substrates allow for greater connection density.
- Reduce energy consumption in high performance applications.
- Increase thermal resistance in data center servers.
- They facilitate the integration of high-bandwidth memories, such as HBM.
Market and global share
Ibiden holds around 50% of the global market for substrates for high-performance semiconductor packages, especially in the server and advanced PC segments. In Nvidia’s AI GPU substrate niche, the company serves as a dominant supplier with high-quality, high-yield mass production.
Analysts point out that competitors face difficulties in achieving the same level of precision and scale. The package substrates market projects double-digit annual growth and could double in size by 2026 or 2027, driven by demand for AI processing.
Productive expansion
Ibiden invests heavily in expanding capacity to meet growing demand. The company builds new factories in Gifu, with partial start-up expected in 2025 and full operation in subsequent years.
The objective increases the production of substrates for AI by up to 2.5 times by 2027, going from three to five factories in three locations. Executivos from the company indicate that, even with these investments, supply may remain tight in 2025 and 2026 due to the accelerated pace of adoption of AI technologies.
These expansions include modernizing existing lines and adopting integrated digital systems for greater efficiency. The strategy prioritizes maintaining quality in high volumes, strengthening the position among global customers.
Strategic partnerships
The relationship with Nvidia is strengthened by early customization of substrates for new chip designs. Ibiden collaborates from the earliest stages of development, tailoring products to the exact specifications of each GPU generation.
This proximity explains the company’s almost exclusive position in supplying Nvidia’s AI chips. Similar Parcerias holds with other giants, such as Intel, which historically represented a large part of revenues, and TSMC, with joint projects in production automation.
Challenges in the sector
The substrate sector faces high technical barriers, including the need for materials resistant to thermal deformation and increasingly thinner layers. Ibiden benefits from decades of technological accumulation, but monitors potential entry of Taiwanese and Korean competitors in specific niches.
Concentration on a few qualified suppliers creates mutual dependence in the advanced semiconductor supply chain. Investimentos in research and development remain priorities to sustain leadership.
Growth outlook
The advancement of artificial intelligence continues to drive the need for more powerful and efficient chips. Servidores of data centers demand larger substrates with more layers, exactly in the areas of strength of Ibiden.
The company is positioned to capture this expansion, with projections of a significant increase in sales of AI components in the coming years. The combination of proprietary technology and expanded production capacity reinforces Ibiden’s central role in the global advanced computing infrastructure.
