- Week 32: Your Expedite Just Stopped Working: Week 32: the buy side got in line, and the line now has a stated length. Microchip says orders placed inside lead time are going unsupported many times a quarter. onsemi's average lead time stretched from about 27 weeks to about 32 in one quarter. Vishay's book-to-bill hit 1.32, with customers ordering beyond 52 weeks to hold production slots, and ISM's Supplier Deliveries index has now slowed for eight straight months. SanDisk put a duration on it: bits stay on allocation beyond calendar 2027, with $93.9 billion committed at floor pricing across eight datacenter and edge customers. The honest counter is that the front end is not full — Microchip reports about $450 million of its own equipment still undeployed, with the constraint at substrates, subcontract assembly and test.
- Week 31: The Shortage Moved to a Material You Don't Buy: Week 31: the shortage stopped being about memory. Lumentum's CEO says indium phosphide is running more than 30% below customer need and will become more acute than the memory squeeze. Corning's Optical Communications grew 32% with its AI data-center line up 65%, GlobalFoundries signed a proposed $300M CHIPS silicon-photonics LOI, and UMC's Singapore photonics cleanroom ramps late 2027. Meanwhile the general-purpose base came back — and Renesas is retiring a 50-year-old 6-inch analog and discrete line without a date. The honest counter: a 94.1% revenue forecast against 7.4% more silicon area shipped.
- Week 26: The Spike Became the Baseline — The Cost Reached the Whole Board: Week 26: TSMC is reported to be hiking every advanced node and DDR2 jumped 55-60%, so the memory spike stopped being a line item and reset the whole bill of materials. The majors are financing a higher cost base — SK Hynix's $29B raise, Micron agreements, onsemi-Synaptics.
- Week 23: The Market Hit $1.5T and Your Memory Quote Got Worse: Week 23 explains why record semiconductor growth and worsening memory quotes are the same story: AI infrastructure is pulling DRAM, NAND, HBM, storage, substrates, and power ahead of traditional buyers.
