Intel poaches SK Hynix's ex-CEO for packaging

Intel (INTC US) has hired former SK Hynix chief executive Lee Seok-hee to run advanced packaging, system integration, and back-end manufacturing, reporting directly to CEO Lip-Bu Tan. Analysts read the move as an attack on TSMC's packaging moat rather than a push into memory.

According to Liberty Times reporting that cites semiconductor analyst commentary, the appointment targets advanced packaging, not HBM. Lee will oversee Intel's EMIB (embedded multi-die interconnect bridge) technology, which lost the GPU-standard battle to TSMC's CoWoS (chip-on-wafer-on-substrate) years ago but is positioned for a second chance as custom AI ASICs and inference accelerators scale.

The reasoning rests on a shift in the industry bottleneck. By 2026 the constraint is packaging, not wafers: CoWoS faces severe capacity shortages and high cost from its large interposers. Intel has carved advanced packaging into a unit reporting straight to the CEO, a structural signal that it intends to make packaging its core weapon against TSMC.

Lee was a central figure in SK Hynix's HBM rise, and the hardest part of AI chip packaging is integrating the GPU and HBM at high yield. In a separate podcast interview, Tan laid out a five-to-ten-year roadmap targeting tenfold shareholder returns, with bets on advanced packaging, glass substrates, and synthetic-diamond materials. NVIDIA and AMD orders locked into CoWoS will not move overnight, but Intel is trying to break TSMC's integrated bundle of leading-edge process plus packaging, the combination that lets accelerators and HBM sit inside one system.

TSMC trims 28nm, lifting UMC and Vanguard

TSMC (2330 TT) has cut monthly wafer starts at Fab 15A, its main 28nm site, by more than 25% since the start of the year. It is redirecting mature-node capacity toward interposers for advanced packaging and pushing some price-sensitive customers toward UMC and Vanguard.

According to Commercial Times supply-chain reporting, Fab 15A monthly 28nm input fell from 200,000 wafers at the start of 2026 to 150,000 by June, as TSMC shifts focus to higher-value nodes. Its A14 (1.4nm) base at Taichung Fab 25 is under construction, with civil works on the P1 site already complete.

The 28nm node remains important for display driver ICs, power management ICs, microcontrollers, networking, and automotive chips, so demand will not vanish quickly. But with TSMC's capex now centered on 2nm, A14, and advanced packaging, its mature-node expansion stance is conservative. As supply tightens, customers seeking a second source stand to benefit UMC (2303 TT), which has a full 28nm platform and is advancing 22nm, and Vanguard (5347 TT), whose new Singapore 12-inch fab is racing to take overflow orders.

The freed-up capacity supports two TSMC priorities. As GPU die sizes approach the reticle limit, TSMC is prioritizing SoIC 3D stacking to add SRAM and I/O dies on top, breaking single-die area and memory-bandwidth limits. On silicon photonics, its COUPE optical engine is moving toward 3.2T, about 2.5x the bandwidth per millimeter of a traditional 1.6T optical module.

Taiwan chip designers pile into co-packaged optics

Taiwan's IC design houses are moving into silicon photonics and co-packaged optics (CPO), led by MediaTek (2454 TT) with affiliate Airoha, as NVIDIA's Vera Rubin platform drives a step-change in optical-interconnect demand.

According to Economic Daily News, MediaTek already has CPO technology running at 400Gbps per fiber and is applying Micro LED optics to active optical cables for data-center interconnect, claiming single-chip CMOS integration with 50% lower power. It invested about US$90m in CPO optical-engine maker Ayar Labs in 1Q26 to widen its position.

Affiliate Airoha expects optical-communications revenue to more than triple this year, with single-channel 50G and 100G PAM4 DSP products already qualified into several of the world's top-ten and top-five optical-module makers and ramping. A newly listed silicon-photonics investee, in which MediaTek Capital holds 9.17%, is developing PIC chips and optical engines.

Veteran designer Elan (2458 TT) has taken a stake above 15% in US-based PETA, splitting work so PETA handles the photonic IC and Elan the electronic IC, including the transimpedance amplifier and laser driver, with a 3.2T near-packaged-optics product targeted for next year. PETA's optical partner is reported to be Largan (3008 TT), which plans its first automated fiber-array pilot line before September and showed a 6.4T multi-channel design at COMPUTEX that chairman Lin En-ping says leads the market by three generations.

Marvell lines up TSMC's A14 for next flagship

Marvell (MRVL US) is in talks to adopt TSMC's A14 (1.4nm) process for future flagship products, president and COO Chris Koopmans said. It signals that custom-silicon and AI-infrastructure leaders are already lining up for TSMC's post-2nm node.

According to cnYES reporting, A14 is TSMC's next logic generation after N2 (2nm) and is slated for 2028 production. Versus N2, TSMC says A14 delivers 10% to 15% more performance at the same power, or 25% to 30% lower power at the same speed, with logic density up more than 20%.

For Marvell's core digital signal processors, Koopmans said power efficiency is paramount, noting that even a 0.1-watt difference matters. Marvell has leaned almost entirely on TSMC for leading-edge nodes despite using Samsung and GlobalFoundries elsewhere, and once skipped 7nm to jump from 16nm straight to 5nm.

Bank of Korea flags chip bonuses as inflation risk

The Bank of Korea has named performance bonuses at Samsung Electronics (005930 KS) and SK Hynix (000660 KS) as a risk to national price stability. It is a sign of how concentrated the AI memory boom's spoils have become.

According to Tom's Hardware, the central bank's June 17 price-stability report warned that payouts worth several hundred thousand dollars per worker could lift wages across the economy. Special pay in the IT sector rose 60.6% YoY in 1Q26, against just 2.1% wage growth elsewhere. The bank held its policy rate at 2.50% in May and projects full-year inflation of 2.7%, above its 2% target.

The scale is large. SK Hynix agreed to set aside 10% of operating profit for bonuses, and Samsung committed 10.5% of semiconductor operating profit after a strike threat in May. A memory worker on a base salary of KRW 80m (US$52,400) could collect roughly KRW 626m (US$410,000) this year; SK Hynix staff could exceed KRW 700m if the company reaches KRW 250tn in annual profit.

The bank modeled how concentrated payouts move prices: when the share of firms paying top-decile bonuses rises, consumer prices climb 0.05 percentage points about five months later. Card spending has risen fastest in the districts around the two firms' fabs, where luxury sales have surged. The payouts trace directly to the AI-driven memory supercycle that has pushed DRAM and NAND contract prices up through 2025 and 2026.

Networking and satellite demand drive record Taiwan May sales

Taiwan's networking and optical-component makers posted record May revenue as 800G switching for AI data centers and surging low-earth-orbit (LEO) satellite broadband demand arrived together.

According to a cnYES research note, Accton (2345 TT) saw May revenue jump 56.58% YoY on 800G switch and AI-accelerator shipments, with higher-end 1.6T switches due to ramp in the second half. In optical, LandMark Optoelectronics (3081 TT) reported revenue up 118.84% YoY as silicon-photonics product shipments surged, helped by rising US customer capex.

On the satellite side, Wistron NeWeb (6285 TT) grew January-to-May revenue 11.6% YoY on LEO subscriber additions and memory-cost pass-through, with enterprise 800G products set to lift margins in the second half. The note frames both networking and optical as on a multi-year growth track tied to AI infrastructure and space broadband.

Tesla dangles up to 5x TSMC pay to poach Taiwan engineers

Elon Musk's "Terafab" wafer-fab venture is reported to be recruiting aggressively in Taiwan, offering three-to-five times TSMC salaries, possibly above US$240,000 plus stock, to draw senior process engineers from TSMC. It underlines Taiwan's role as the industry's talent reservoir as global players race to build fabs. (22 Jun 2026) Source: 國際大廠挖角砸錢不手軟 特斯拉開出台積五倍薪資+股票激勵計畫
