[News] Samsung Signals Will to Collaborate with Other Foundries on Basedie

At the SEMICON Taiwan 2024, Samsung’s Head of Memory Business, Jung Bae Lee, stated that as the industry enters the HBM4 era, collaboration between memory makers, foundries, and customers is becoming increasingly crucial.

Reportedly, Samsung is prepared with turnkey solutions while maintaining flexibility, allowing customers to design their own basedie (foundation die) and not restricting production to Samsung’s foundries.

As per anue, Samsung will actively collaborate with others, with speculation suggesting this may involve outsourcing orders to TSMC.

Citing sources, anue reported that SK hynix has signed a memorandum of understanding with TSMC in response to changes in the HBM4 architecture. TSMC will handle the production of SK hynix’s basedie using its 12nm process.

This move helps SK hynix maintain its leadership while also ensuring a close relationship with NVIDIA.

Jung Bae Lee further noted that in the AI era, memory faces challenges of high performance and low energy consumption, such as increasing I/O counts and faster transmission speeds. One solution is to outsource the basedie to foundries using logic processes, then integrate it with memory through Through-Silicon Via (TSV) technology to create customized HBM.

Lee anticipates that this shift will occur after HBM4, signifying increasingly close collaboration between memory makers, foundries, and customers. With Samsung’s expertise in both memory and foundry services, the company is prepared with turnkey solutions, offering customers end-to-end production services.

Still, Jung Bae Lee emphasized that Samsung’s memory division has also developed an IP solution for basedie, enabling customers to design their own chips. Samsung is committed to providing flexible foundry services, with future collaborations not limited to Samsung’s foundries, and plans to actively partner with others to drive industry transformation.

Reportedly, Samsung is optimistic about the HBM market, projecting it to reach 1.6 billion Gb this year—double the combined figure from 2016 to 2023—highlighting HBM’s explosive growth.

Address the matter, TrendForce further notes that for the HBM4 generation base die, SK hynix plans to use TSMC’s 12nm and 5nm foundry services. Meanwhile, Samsung will employ its own 4nm foundry, and Micron is expected to produce in-house using a planar process. These plans are largely finalized.

For the HBM4e generation, TrendForce anticipates that both Samsung and Micron will be more inclined to outsource the production of their base dies to TSMC. This shift is primarily driven by the need to boost chip performance and support custom designs, making further process miniaturization more critical.

Moreover, the increased integration of CoWoS packaging with HBM further strengthens TSMC’s position as it is the main provider of CoWoS services.
