Initiating a strategic partnership, South Korean semiconductor giant SK Hynix has announced collaboration with Taiwan’s TSMC, the leading foundry in the world, to fortify their capabilities in next-generation high-bandwidth memory (HBM) production and advanced packaging technologies. They plan to unveil the development of the 6th generation HBM, HBM4, by 2026, after signing a Memorandum of Understanding (MOU) in Taipei, Taiwan.
AI chip market pioneers like NVIDIA currently rely on SK Hynix for the supply of HBM, essential for their graphics processing units (GPUs), which is then packaged by TSMC. Through this new partnership, the companies are set to improve the performance of the base die at the bottom of HBM packages. The base die serves as a mediator connecting the GPU with the HBM and managing its operations.
To date, SK Hynix has produced base dies using its DRAM process up to the 5th generation HBM, HBM3E. However, future generations starting with HBM4 will integrate TSMC’s advanced logic fine processing to add various system functions.
Furthermore, both firms will collaborate to enhance the integration of SK Hynix’s HBM with TSMC’s sophisticated packaging process, “Chip on Wafer on Substrate” (CoWoS), and will jointly address customer needs related to HBM technologies.
The President of SK Hynix’s AI Infrastructure Division emphasized the acceleration of developing superior HBM4 performance and the intent to establish a more open and collaborative relationship with global customers. This aligns with their goal to become a prominent ‘total AI memory provider.’ TSMC’s Senior Vice President highlighted the sustained, robust partnership with SK Hynix and their shared history of providing top-tier AI solutions combining cutting-edge logic chips with HBM, asserting their commitment to deliver premium integrated products that will be pivotal for customer AI innovations with HBM4.
Strategic Implications and Challenges
A significant challenge in the production of high-bandwidth memory is the continuous need for miniaturization while increasing performance and capacity. Every new generation of HBM necessitates advances in fabrication technology, packaging, and interconnects to meet these demands. The collaboration between SK Hynix and TSMC is poised to address these challenges through combined expertise in DRAM production and advanced packaging technologies.
Advantages and Disadvantages
The main advantage of this collaboration is the enhancement of both companies’ competitiveness in the high-growth sectors of AI, machine learning, and high-performance computing. By pooling their resources, SK Hynix and TSMC can accelerate the developmental timeline and potentially reduce R&D costs. The integration of TSMC’s advanced logic fine processing with SK Hynix’s HBM technology will likely result in a superior product in terms of performance and functionality.
On the downside, as the complexity of the HBM increases, the costs and risks associated with the development and manufacturing also rise. Additionally, the partnership could face challenges from regulatory bodies, particularly concerning competition laws, and from geopolitical tensions that may affect supply chain stability.
Relevant Questions and Answers
1. What is high-bandwidth memory (HBM)?
HBM is a type of memory characterized by a wide interface and stacked architecture, offering high-speed data transfer and high bandwidth, which is critical for processing large and complex data sets in AI and GPUs.
2. Why is enhanced base die performance important?
The base die is essential because it interfaces with the GPU or other processors and manages the operation of stacked memory dies in HBM. An enhanced base die could lead to better efficiency, lower latency, and improved overall performance of the memory stack.
3. How does TSMC’s CoWoS technology contribute to HBM?
TSMC’s CoWoS (Chip on Wafer on Substrate) is an advanced packaging technology that allows for the integration of different chips, such as HBM and logic dies, into a single package. This not only saves space but also enables higher performance due to shortened data paths.
