  HBM competition [Posting: 2025.08.18] In 2025, the HBM (High Bandwidth Memory) market is hotter than ever due to the explosive demand for AI accelerators. Among the global Big Three (SK hynix, Samsung Electronics, and Micron), SK hynix is solidifying its dominance by leading both technology and market share. It became the world’s first to mass-produce HBM3E 12-Hi and took the lead by supplying HBM4 samples in advance, securing its position as a key partner for NVIDIA’s B200. Micron is rapidly expanding its market share by leveraging the speed and power efficiency of HBM3E, emerging as a “dark horse.” On the other hand, Samsung Electronics, despite having strong specifications, has slowed down due to certification and yield issues, making recovery its main task. The revenue share of HBM within the overall DRAM market has risen sharply, and profitability has significantly improved thanks to high ASPs and advanced stacking technologies. However, the possibility of oversupply and pri...

  DB HiTek - Korea base [Posting: 2025.08.18] DB HiTek is Korea’s leading specialized 8-inch (200mm) foundry, with strengths in analog and power semiconductor fields such as BCD, HV CMOS, Mixed-Signal, display driver ICs, and CMOS image sensors. In particular, the company demonstrates differentiated legacy process capabilities in automotive and industrial power semiconductors as well as display driver chips compared to global competitors. Currently, DB HiTek operates two fabs in Bucheon and Eumseong with a monthly capacity of 150,000 wafers, and by 2026, it plans to expand its infrastructure to around 190,000 wafers per month. The company is also preparing new growth drivers by expanding its technology portfolio into next-generation embedded memory ReRAM and SiC/GaN-based power semiconductors. However, compared to the global top four foundries, DB HiTek is smaller in scale and has a limited presence in the 12-inch advanced node segment. Nevertheless, backed by a stable profit struc...

This structure allows the company to meet diverse demands, from low-power analog devices to advanced data center SoCs. Although the recent decline in revenue and shift to operating losses pose challenges, MaxLinear is expanding its application areas to Wi-Fi 7, 5G, cloud data centers, and automotive electronics, offering opportunities for a rebound. Ultimately, the company’s competitiveness depends on its expertise in RF and mixed-signal design, diversification of foundry partners...

Baidu [Posting: 2025.08.16] China’s Baidu started as a search engine but has now become a leading tech company with artificial intelligence (AI) and autonomous driving as its core growth pillars. Leveraging the vast data accumulated from search and advertising, Baidu has advanced generative AI (ERNIE), the deep learning framework (PaddlePaddle), and the cloud platform (Qianfan) . In autonomous driving, it operates the world’s largest pilot services through its Apollo Go robotaxi and the RT6 vehicle . Its semiconductor capabilities are also noteworthy. Baidu has developed its own AI accelerators — Kunlun I (Samsung 14nm) and Kunlun II (reportedly TSMC 7nm) — while simultaneously deploying NVIDIA H100 and Huawei Ascend 910B/910C chips to strengthen its data centers and research infrastructure. This reflects a strategy of diversified sourcing in response to U.S. export restrictions and supply chain risks. Looking ahead, Baidu’s prospects depend on whether it can reduce reliance on ...

  SK Hynix [Posting: 2025.06.10] SK hynix is transitioning from a conventional memory supplier to a global leader in AI memory and High Bandwidth Memory (HBM) . As a key HBM supplier to NVIDIA , a pivotal player in the AI era, the company is benefiting significantly from the AI boom . SK hynix currently produces DRAM (70%) and NAND (30%) , and is planning to build the Yongin Mega-FAB with a monthly capacity of 800,000 wafers , scheduled for completion in 2027 , to aggressively expand market share. Although the company posted a $5 billion operating loss in 2023 , it rebounded with a record-high operating profit of $16.3 billion in 2024 thanks to strong HBM demand —placing SK hynix at the very center of the global AI trend. In data centers, a technology alliance is being formed with NVIDIA's GPUs , TSMC's advanced logic buffer dies , and SK hynix's HBM , establishing a strong foundation of trust in both technology and quality and giving SK hynix a competitive edge over ...
