Original: '뻥튀기 상장' 의혹 파두 첫 공판…“사기 상장” vs “예측 실패”
Fadu's first criminal trial opened with prosecutors alleging executives concealed order halts from SK Hynix (which cut projected orders from 1.2M to 350K units in Jan 2023, then suspended further orders through Q3 2024) and SpaceX (post-Starship failure) to push through a KRW 1.5T KOSDAQ IPO in Aug 2023. Defense counters that revenue estimates were conservatively revised down (KRW 247B → 119B), blames the 2023 chip downturn, and notes KRX already cleared Fadu for relisting in Feb 2026. Prosecutors also allege bribery via shadow shares of Moreh given to a former SK Hynix strategy exec in exchange for vendor selection.
Why it matters: Fadu (unlisted in universe) IPO-fraud trial is a major KR semi-governance story with SK Hynix (000660) named as the key customer whose order cuts triggered the case, but the impact on Hynix itself is reputational/peripheral rather than near-term operational.
Original: 合晶矽光子、碳化矽晶圓報捷 三地同步大擴產
Wafer Works (6182-TW) said at its AGM that silicon photonics applications have completed customer adoption and SiC materials are pushing into advanced packaging thermal management, with FY revenue of NT$9.82B (+12.6% YoY). The group is expanding three fabs in parallel — Erlin (advanced-process Si wafers ramping to 100k/month by mid-2027), Zhengzhou phase 2 (75k/month by mid-2027) and Zhunan GaN (2k/month by year-end) — and skipped a cash dividend to preserve capex flexibility.
Why it matters: Capacity expansion and silicon photonics / SiC advanced-packaging adoption is a supply-chain signal for AI/advanced-packaging demand, but Wafer Works (6182) is not in the tracked universe and no tracked customer is explicitly named.
Open source articleOriginal: SK하이닉스, HBM4E 샘플 공급...격화하는 HBM 전쟁 - chosun.com
SK Hynix has begun shipping samples of its 7th-generation HBM4E (12-high) to customers, moving ahead of rivals in the next-gen AI memory race. The move pressures Samsung and Micron to accelerate their own HBM4E roadmaps as hyperscalers and NVIDIA lock in supply for next-generation AI accelerators.
Why it matters: SK Hynix's HBM4E sampling is a direct competitive milestone in the highest-margin memory segment, with immediate read-through to Samsung, Micron, and NVIDIA's AI roadmap.
Open source articleOriginal: 解密800VDC延後傳聞！相關供應鏈該不該買？
SemiAnalysis reports the 800VDC architecture for AI servers will be delayed beyond 2028 as hyperscalers favor 400VDC to avoid double-conversion losses, but Nvidia's Vera Rubin will still partially adopt 800VDC with broader penetration at Rubin Ultra/Feynman. Taiwan power and BBU names (Delta 2308, Lite-On 2301, Sunrise 3211, AES-KY 6781, Wits 6761, Chant Sincere 3003, Speedy-Tech 3665, Yageo 2327) remain beneficiaries as 400VDC ramps near-term and 800VDC scales longer-term.
Why it matters: Sector-level roadmap commentary on AI server power architecture timing with a recommended beneficiary list, not a hard catalyst or contract win.
Open source articleOriginal: 邁威爾洽台積 A14 製程 COO：高速傳輸是 AI 關鍵
Marvell COO Chris Koopmans said the ASIC and interconnect specialist is in talks with TSMC to adopt the foundry's A14 (1.4nm) process for next-generation products, with A14 mass production targeted for 2028. Marvell has consolidated all wafer output at TSMC after previously using Samsung and GlobalFoundries, and is leaning on high-speed connectivity chips as a core AI data-center building block.
Why it matters: Roadmap/supply-chain story reinforcing TSMC's leading-edge customer pipeline rather than a near-term order or capex commitment; A14 ramp is 2028.
Original: 陳文琦：AI帶動科技大海嘯 威盛拿下3奈米ASIC案進軍AI光通訊
VIA (2388) Chairman Wen-Chi Chen said at the AGM that AI demand is creating a 'tech tsunami,' with supply chains tighter than during COVID. VIA has secured 3nm ASIC projects with TSMC (2330) capacity support, alongside 6nm products, and is accelerating into AI optical communications via VCSEL/photonics M&A including a $9.23M acquisition of TRUMPF Photonic Components' consumer sensor assets and a NT$1B injection into MicroJet plus a share swap for VCSEL maker Hualijie.
Why it matters: Confirms TSMC 3nm ASIC traction and a real photonics M&A roadmap at VIA, but VIA itself is not in the tracked universe and TSMC exposure is incremental rather than a stock-moving disclosure.
Original: 엔비디아 베라 루빈 NVL72 정식 출하…CoreWeave·오라클에 최초 공급
NVIDIA has officially delivered its next-generation Vera Rubin NVL72 AI platform to CoreWeave and Oracle, marking the first commercial deployment of the successor to Blackwell. The launch reinforces NVIDIA's AI infrastructure dominance and accelerates capex cycles for hyperscaler customers, with downstream demand implications for HBM, advanced packaging, and networking suppliers.
Why it matters: First commercial delivery of NVIDIA's Rubin-generation rack-scale AI platform is a direct product-launch event with major downstream impact on HBM, packaging, and networking suppliers.
Original: 슈퍼마이크로, NVIDIA Vera Rubin NVL72·HGX Rubin NVL8 기반 DCBBS 로드맵 공개…5MW~1GW 통합 솔루션
Supermicro announced its Data Center Building Block Solutions (DCBBS) roadmap leveraging NVIDIA's next-gen Vera Rubin NVL72 and HGX Rubin NVL8 platforms, offering end-to-end deployments scaling from 5MW to 1GW. The move strengthens Supermicro's positioning in the AI infrastructure buildout cycle and reinforces NVIDIA's Rubin platform as the backbone of hyperscale AI data centers.
Why it matters: Reinforces NVIDIA Rubin platform momentum and AI data center infrastructure demand, indirectly supporting the broader semi supply chain.
Open source articleOriginal: 〈台股盤後〉電子股多點開花漲587點收46465點新高 周漲2296點
Taiwan's TAIEX closed at a fresh record 46,465.2 (+1.28%, +587 points) on Wednesday with turnover swelling to NT$1.54T, capping a weekly gain of 2,296 points (+5.2%) despite a hawkish Fed. TSMC (2330) rose 1% to NT$2,410 while ASE (3711) and UMC (2303) gained 3%, IC design names Silergy (6415) and Realtek (2379) hit limit-up, and panel maker AUO (2409) jumped 7% alongside limit-up moves in passives and packaging plays.
Why it matters: Broad market wrap with multi-sector rally and record index close, but no single stock-moving catalyst beyond the rising-tide tape.
Original: HBM 특허전 재점화…넷리스트, 삼성전자 상대 신규 소송 - v.daum.net
Memory IP firm Netlist has filed a fresh HBM-related patent infringement lawsuit against Samsung Electronics, reigniting a long-running legal battle over high-bandwidth memory technology. The renewed litigation adds another overhang to Samsung's HBM business as it tries to close the gap with SK Hynix in the AI memory race, with potential damages and injunction risk if Netlist prevails.
Why it matters: Company-specific legal risk for Samsung's HBM business with potential indirect benefit to SK Hynix, but litigation outcomes are typically slow-moving and not an immediate share-price catalyst.
