Samsung and Broadcom forge $200 billion AI chip partnership to challenge TSMC's dominance

Samsung Broadcom Partnership Targets AI Chip Manufacturing Through 2030

Samsung Electronics and Broadcom announced a memorandum of understanding valued at more than $200 billion, marking one of the largest semiconductor partnerships ever disclosed 1

1

. The five-year strategic collaboration in memory and foundry technologies runs through 2030 and addresses critical components of next-generation AI infrastructure 3

3

. The deal was announced during the AI Summit held in San Francisco, with senior executives from both companies and Korean government representatives in attendance 4

.

The Samsung Broadcom partnership comes as global technology companies increasingly develop custom AI chip designs rather than relying solely on general-purpose graphics processors from Nvidia, driving demand for specialized manufacturing partnerships 1

. Broadcom designs custom AI accelerators for hyperscalers including Google and Meta that want silicon tailored to specific workloads 3

3

. The company extended its AI chip partnership with Meta through 2029 in April, and CEO Hock Tan recently indicated that surging AI revenue has made organic growth more attractive than acquisitions 3

Advanced AI Hardware Development Using Sub-2-Nanometer Process

The foundry component of the deal centers on Samsung's sub-2-nanometer process technology and smaller nodes for manufacturing Broadcom products at its Pyeongtaek, South Korea campus 3

3

. Broadcom's next-generation communications chips, designed for high-speed data transfer, will be produced using these leading-edge manufacturing capabilities, putting them at the forefront of chip scaling where efficiency and heat management present increasing challenges 1

. These techniques integrate memory and logic more tightly, a method increasingly central to extracting maximum performance from AI semiconductor designs 3

3

. The focus on advanced packaging reflects how performance gains are increasingly tied to how chips, memory, and packaging work together rather than improvements in any single component 2

High-Bandwidth Memory Supply for AI Accelerators

On the memory front, Samsung will supply Broadcom with industry-leading high-bandwidth memory solutions, including HBM4 and HBM4E chips, for use in Broadcom's next-generation AI accelerators 3

. Last month, Samsung co-CEO and chip division head Jun Young-hyun discussed next-generation foundry cooperation with Jensen Huang, chief executive of Nvidia, including future HBM4E and HBM5 memory products 1

.

Samsung posted record quarterly operating profit of 89 trillion won in Q2, driven almost entirely by AI memory demand, highlighting the financial significance of securing long-term customers for these products 3

3

. The deal combines Broadcom's expertise in designing application-specific integrated circuits, or ASICs for specific tasks, with Samsung's manufacturing capabilities across the semiconductor stack 1

Strengthening Foundry Position Against TSMC in High-Performance Computing

For Samsung, the partnership addresses a persistent credibility gap in its foundry business, where its global market share has fallen to roughly seven percent while TSMC dominates with more than 90 percent of leading-edge chip production 3

3

. Winning long-term production commitments from Broadcom, one of the world's leading custom AI chip designers, could boost utilization at Samsung's advanced manufacturing facilities and help narrow the gap with industry leader TSMC 1

Samsung said this year it expected to secure more advanced 2-nanometer foundry orders in the near term after discussions with major tech companies 1

1

. Last year, the company won a $16.5-billion contract to make logic chips for EV maker Tesla 1

1

. However, the Broadcom agreement stands out for its scope, covering multiple parts of the semiconductor process rather than a single product line 2

2

.

By diversifying manufacturing to Samsung, Broadcom gains supply chain resilience beyond its existing reliance on TSMC, which controls the vast majority of leading-edge production 3

3

. The signing took place alongside a broader package of semiconductor deals worth roughly $950 billion between South Korean and American companies announced during the AI Summit hosted by South Korean President Lee Jae Myung 3

3

. SK Hynix signed memory partnerships worth $750 billion with Nvidia and others, while the summit followed Seoul's $880 billion domestic investment plan unveiled in June, which committed Samsung and SK Hynix to building four new chip fabrication plants in the country's southwest 3

3

. With capabilities encompassing memory, logic, foundry and advanced packaging, Samsung positions itself to deliver integrated semiconductor solutions for the AI era, though the company has struggled with yields on its two-nanometer process 3
