Round-up
Highlights
- Broadcom starts shipping its 3 nm “Tomahawk 6” Ethernet switch, doubling port speed to 1.6 Tbit/s and promising to cut AI-cluster switch counts by half12.
- The White House plans to waive key Defense Production Act hurdles to fast-track domestic critical-mineral projects—an echo of CHIPS, but for the raw materials behind it3.
- Nvidia’s market cap leap-frogs Microsoft at $3.45 trillion after a fresh Blackwell margin boost, even as it quietly works on a “China-compliant” AI GPU45.
Other developments
- Barclays downgrades ASML, warning 2026 growth hinges on just three High-NA EUV shipments6.
- GlobalFoundries commits €1.1 billion (~$1.19 billion) to expand its Dresden fab, chasing European automotive and IoT demand7.
- Samsung hires former Intel/TSMC veteran Margaret Han to run its U.S. foundry push8.
- Capitol Hill briefing today sees SIA press lawmakers for faster CHIPS outlays and workforce visas9.
- Nuveen trims its ASML stake by 1.4 million shares ahead of the downgrade10.
- Infineon debuts 80 / 100 V OptiMOS & MOTIX parts for UAV motor drives11.
- Tower Semi to unveil a pSemi co-designed RF switch at IMS 2025, aiming at 5G handsets12.
Did you know? A single 1.6 Tbit/s Tomahawk 6 chip can move 230 GB of data every second—the equivalent of copying a full Blu-ray disc about 46 times in that blink2.

2. Economics, Finance & Business Outlook
-
ASML downgrade checks equipment rally
- Barclays cuts target from €770 to €650, citing Intel and Samsung cap-ex pauses and tepid High-NA uptake—an interesting reversal after yesterday’s newsletter noted fund rotation into wafer-tool names6.
-
GlobalFoundries’ Dresden upgrade
- New clean-room adds 12K wafer starts/week for 22 FDX and SiGe lines, with Saxony state covering 20% of costs7.
-
Nvidia tops U.S. market cap table
- Stock closes at $141.40 (+2.9%), buoyed by Jefferies’ “top pick” call and 70–80% projected GM on Blackwell4.
-
Institutional flows
- Nuveen sheds ~$600 million of ASML shares, while smaller funds pile into Applied Materials and Lam, underscoring mixed sentiment on the equipment cycle10.
3. Technology & R&D
-
Broadcom Tomahawk 6 lands
-
Infineon OptiMOS/MOTIX for UAVs
- 80 / 100 V devices hit 97% efficiency in Reflex Drive quad-rotor tests; integrates programmable gate driver to slash BOM by 20%11.
-
Tower Semi + pSemi RF switch
- IMS 2025 paper touts sub-0.15 dB insertion loss at 6 GHz using SOI-based MEMS actuation; sampling to handset OEMs this quarter12.
-
Next-gen materials & compute
- Researchers demo self-healing stretchable transistors patterned at wafer scale—key for neural implants14.
- Overlapping moiré lattices in stacked 2D semiconductors yield tunable flat-band quantum states, hinting at programmable qubits15.
- Germany’s Q.ANT will run the first public hands-on with its photonic NPS co-processor at ISC 2025, claiming 10× energy gains over GPUs for CFD workloads16.
