X-FAB: A Specialist Foundry Leveraging Legacy Strengths for Future Growth

Image
  X-FAB [Posting: 2025.08.22] X-FAB has established itself as a specialized foundry in analog, mixed-signal, high-voltage (HV), MEMS, and SiC technologies , distinguishing its strategy from large-scale competitors focused on cutting-edge nodes. Instead of competing at the most advanced geometries, X-FAB has built its business around legacy and specialty processes ranging from 1.0µm to 110nm , where demand remains steady. This positioning has made the company a trusted partner in markets that demand high reliability and durability , particularly automotive electronics, industrial control chips, and medical sensors. One of X-FAB’s defining capabilities is its ability to deliver automotive-grade (Grade-0) qualified processes . Its 110nm BCD-on-SOI platform and SiC-based power semiconductor technologies are increasingly critical as the shift to electric and autonomous vehicles accelerates. In parallel, the company leverages MEMS and RF-SOI platforms to expand into wireless communica...

Renesas Electronics: Expanding Beyond MCUs into Power, Analog, and Connectivity

Image
  Renesas [Posting: 2025.08.22] Renesas Electronics is a representative Japanese semiconductor company that has built its global leadership on automotive MCUs and SoCs . The company’s expertise lies in providing comprehensive solutions that integrate microcontrollers, analog and power devices, timing ICs, and connectivity solutions . With acquisitions of Intersil, IDT, Dialog, Celeno, and most recently Transphorm, Renesas has expanded its product breadth far beyond controllers, strengthening its capabilities in power management, wireless connectivity, and wide bandgap (GaN) power semiconductors . In terms of semiconductor technology, Renesas has a dual strategy : it collaborates with TSMC for advanced nodes (28nm eFlash, 16nm, 12nm, and even 3nm for R-Car SoCs) while investing in in-house production, such as the Kofu 300mm fab dedicated to power semiconductors . This approach ensures both access to cutting-edge logic processes and secure supply of critical automotive and industrial...

Intel: From Past Dominance to Future Challenges: Intel’s Roadmap Ahead

Image
  Intel [Posting: 2025.08.20] For decades, Intel has stood as the undisputed leader in PC and server CPUs, backed by its strengths in high-performance processor design , massive global manufacturing infrastructure , and advanced packaging technologies such as Foveros and EMIB . Its portfolio reflects this breadth: the hybrid-architecture Alder Lake , the AI PC–driven Meteor Lake (Core Ultra) , the data center–oriented Xeon family , and the Gaudi AI accelerators . In recent years, Intel has shifted to a multi-foundry strategy , outsourcing certain GPU, CPU, and AI tiles to partners like TSMC, marking a departure from its historic “Intel-only” model. Yet, since 2022, revenues and profitability have sharply declined, with 2024 even recording operating losses due to restructuring and internal foundry transition costs. Looking ahead, Intel’s greatest challenge is the successful ramp of Intel 3, 20A, and 18A process technologies , while regaining competitiveness in the AI and data center...

[Semiconductor] HBM Packaging in 2025: From MR-MUF and TC-NCF to Hybrid Bonding as the Next Standard

Image
  HBM Packaging  [Posting: 2025.08.19] In 2025, the competition in HBM packaging centers on the evolution of stacking methods. SK hynix , with its MR-MUF process, has stably mass-produced 12-Hi stacks, securing advantages in thermal paths and yield, and is preparing for 16-Hi expansion. Samsung Electronics emphasizes mechanical compatibility by implementing 12-Hi at the same height as 8-Hi through precise TC-NCF stacking, while differentiating with its I-Cube/H-Cube platforms for logic integration. Micron challenges the HBM3E market with a focus on power efficiency , strengthening its position through adoption in NVIDIA’s H200. For next-generation HBM4 , featuring a 2,048-bit interface and 2 TB/s bandwidth, hybrid bonding is emerging as an essential technology. While MR-MUF and TC-NCF coexist in the current generation, hybrid bonding is expected to become the standard going forward. Complete Analysis of HBM Packaging Stacking Methods: MR-MUF vs. TC-NCF vs. Hybrid Bonding...

[Semiconductor] 2025 HBM Memory Technology Overview: HBM3E Competition and the Road to HBM4

Image
  HBM Stack [Posting: 2025.08.19] The 2025 HBM market can be summed up with two keywords: HBM3E as the mainstream and HBM4 as the turning point . SK hynix has demonstrated technological leadership with mass production of 12-Hi 36GB and MR-MUF packaging , while preparing for 16-Hi expansion to pursue both higher bandwidth and larger capacity. Samsung is differentiating itself with low-power HBM3E based on HKMG and its I-Cube/H-Cube packaging , whereas Micron has leveraged its 1β node for efficiency and low power, securing adoption in NVIDIA’s H200 . Across the board, vendors are achieving 9.2–9.6 Gb/s pin speeds and over 1.2 TB/s bandwidth , with HBM4 aiming for 2 TB/s per stack via a 2,048-bit interface . However, challenges remain, including thermal and yield issues in 16-Hi stacking and limited CoWoS packaging capacity . Ultimately, the HBM race is no longer just about DRAM technology—it is a comprehensive battle of process nodes, packaging, and ecosystem control , shaping th...
