What happened
Tower Semiconductor received USD 290M in customer prepayments alongside USD 1.3B in contracts for 2027 silicon photonics work, with larger 2028 commitments and another prepayment expected in January 2027.S1 These agreements reserve 300mm silicon photonics capacity for 2027 production.S1 Tower described the commitments as a minimum rather than a limit on future demand.S1
Soitec began pursuing multi-year photonics-SOI capacity reservations with deposits linked to committed volumes, while more than 10 photonics customers were involved and roughly 80% of the agreements were expected to be signed within weeks.S1 The source placed Soitec's share of the photonics-SOI substrate market at about 95% and said its photonics-SOI revenue exceeded USD 100M in the fiscal year ended March 2026.S1 The company did not expect to need another fab until around 2029.S1
STMicroelectronics was negotiating 1–3 year capacity agreements that covered volumes, pricing, and cash advances for silicon photonics production at its Crolles 300mm plant.S1 The source listed Tower Semiconductor, GlobalFoundries, STMicroelectronics, UMC, and Samsung Foundry as the principal merchant-fab set and noted that UMC planned to open its own 300mm platform to general customers in 2027.S1 Samsung Foundry also targeted foundry service in 2027 and turnkey co-packaged optics in 2029.S1

Background timeline
XAIPART take
Technical impact
XAIPART analysis: Buyers designing photonically integrated circuits should qualify process platforms and packaging routes before committing 2027 production volumes. The reported foundry set is expanding, but process interfaces, wafer formats, yield, and integration requirements may make nominal capacity non-substitutable. Engineering teams should document those qualification gaps rather than count every announced 300mm line as equivalent supply.
Market impact
XAIPART analysis: Deposits and long-term agreements indicate that suppliers are attempting to secure demand before new capacity is available, which can lengthen procurement visibility and constrain flexible allocation. Tower Semiconductor, Soitec, and STMicroelectronics appear especially relevant to capacity and substrate risk, although the source did not disclose quoted prices, current lead times, minimum order quantities, or termination terms.
Action
XAIPART analysis: Request wafer allocation, deposit schedules, reservation terms, and 300mm capacity dates from each shortlisted foundry, then map qualified alternatives by platform and package. Do not treat announced 2027 openings as confirmed production supply until the source or supplier provides volume, yield, qualification, and delivery data.
XAIPART Forecast
XAIPART analysis: By the end of 2027, XAIPART expects at least one named merchant foundry to report qualified 300mm silicon photonics capacity for optical-engine customers, with UMC and Samsung Foundry serving as the primary checkpoints; this forecast is wrong if neither supplier has commercially qualified 300mm output by December 31, 2027.

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Uncertainty remains because this brief uses one source, and the source does not provide independent confirmation, quoted commercial terms, current lead times, or complete capacity schedules.
Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
