The competition between Samsung and TSMC has intensified not only in securing international IC design clients but also in the field of South Korean IC design companies. According to a report by ZDNet Korea, major South Korean AI semiconductor fabless companies, which previously used Samsung’s foundry facilities, are now diversifying their manufacturing by using TSMC’s fabs for new chip mass production.

Industry sources cited by ZDNet Korea reveal that FuriosaAI initially used Samsung’s 14nm process for its first-generation chip, “Warboy,” but switched to TSMC’s 5nm process for its second-generation chip, “Renegade.” Notably, Renegade became the first chip in South Korea’s AI semiconductor sector to utilize 2.5D packaging technology with CoWoS and HBM3 memory. FuriosaAI is also planning to use TSMC’s 5nm process for its next-generation chip, “RenegadeS,” set to launch in the fourth quarter.

Similarly, DeepX, after using Samsung’s foundry process, adopted TSMC’s technology for its latest chip development this year. The company’s “DX-V3” system-on-chip (SoC) is being developed using TSMC’s 12nm process, with a target to release samples later this year. DeepX’s earlier chips, the “DX-M1” AI accelerator and “DX-H1” AI server accelerator, were produced using Samsung’s 5nm process, while the “DX-V1” AI SoC solution was made with Samsung’s 28nm process. The “DX-M1” entered mass production last month. ZDNet Korea also reports that DeepX is currently discussing with Samsung the development of next-generation chips using processes more advanced than 5nm.

Another South Korean IC design company, Moblinet, is utilizing both Samsung and TSMC’s foundry services. Its first-generation chip, “Eris,” was manufactured using Samsung’s 14nm process and began mass production in March this year. The second-generation chip, “Regulus,” is being produced using TSMC’s 12nm process and is expected to launch next year after completing testing.

ZDNet Korea also cites industry experts who emphasize that Samsung’s foundry services need to not only focus on attracting large clients but also improve services for smaller fabless companies. Similar to how TSMC grew by nurturing partnerships with small fabless firms, Samsung should bolster its process technology and develop an ecosystem for IP and fabless companies.

According to TrendForce data, TSMC maintained a global foundry market share of 62.3% in the second quarter of this year, while Samsung held an 11.5% share.

Meanwhile, in the race for major international client orders, WCCFTECH reports that Qualcomm is pursuing a dual-sourcing strategy for its Snapdragon 8 Gen 5 chip, partnering with both TSMC and Samsung. Qualcomm has previously attempted this approach, but Samsung’s inconsistent yields thwarted the plan. Qualcomm is now reportedly considering TSMC’s 3nm ‘N3P’ technology for the high-performance variant of the Snapdragon 8 Gen 5, while Samsung’s SF2, also known as 2nm GAA, is expected to be used for a lower-end version.
