When we got it wrong, we say so

STMicroelectronics' Form 6-K (Jul 30, 2026) states that in the second quarter of 2026 it 'started our manufacturing activities and entered into the ramp-up phase' of the new 200mm silicon carbide manufacturing in Catania. The date shown is the end of that quarter (Jun 27, 2026); ST gives no exact day. The filing refers to the 200mm manufacturing; the separate substrate plant on the campus was not separately confirmed.

Coverage of SK hynix's Q2 2026 earnings call says M15X's cleanroom opened in October 2025, wafer input began in the first quarter of 2026, and SK hynix expects to ramp volume gradually (and to accelerate the schedule further). The date shown is the end of Q1 2026; no exact day was given. The record previously showed Under Construction.

The U.S. CHIPS program's project page lists an expected capital expenditure of $105 million for the Nashua modernization (up to $35.5M of it from a finalized CHIPS award); the record showed $1.24 billion, about 12x too high.

The CHIPS program page says the project is expected to be completed by approximately 2028; the record showed 2026.

An earlier correction in this log moved this entry from Austin to Santa Clara. The EPIC Center is actually on Applied Materials' existing campus in Sunnyvale, CA (next to its Maydan Technology Center on Arques Avenue), so the city and map pin are corrected again. The map pin is city-level, not the exact site.

No completion date has been published for SkyWater's Bloomington modernization; the CHIPS award is still described as a proposed preliminary term sheet. The record's Jan 2026 date had no source.

X-Fab's May 2023 announcement of the $200 million Lubbock expansion gave no completion date, and no 2026 confirmation that the expanded capacity is running was found. The record's Jan 2025 date had no source and has already passed.

The joint ST/GlobalFoundries Crolles fab has been reported as stalled since early 2025, and a Jan 2026 report says GlobalFoundries has not met its commitments; no revival or new production date was found. The original full-capacity-in-2026 target is no longer realistic, so the date is removed. ST's own separate Crolles expansion decision (expected by end-2026) is a different project.

The record's Jan 2025 date has already passed and no company or government source for any production date was found (public site-level disclosure for this project is limited), so the date now shows TBD rather than a stale, unsourced one.

Multiple sources consistently describe the Dresden fab as a roughly EUR 1 billion investment, Bosch's largest single investment in its 130+ year history at the time (about $1.1B at the prevailing exchange rate). Further incremental investment was announced in 2022-2023, but no single total near the record's $3.0B was found.

Coverage of onsemi's Aug 2022 expansion celebration describes a $150 million investment already made, with plans for a further $300 million through 2023 (about $450M total); the record showed $2.0B, off by roughly 4-5x.

onsemi's own release (Aug 2022) describes the expanded facility as already increasing SiC boule production capacity by 5x year-over-year; the record showed Under Construction with a 2026 target, which does not match.

Vermont's federal CHIPS funding ($125M) supports a $900 million 'Fab 9' expansion at GlobalFoundries' Essex Junction (Burlington area) site, per Vermont media coverage (Feb 2024). The record's $4.0B figure appears to have used a combined New York + Vermont total instead of the Vermont-specific figure.

Press coverage of the CHIPS award (up to $32M in federal funding) describes Corning's own investment in the Canton expansion as $315 million; the record showed $275M.

KLA's investment grew in stages: $70M (announced Oct 2018), raised to $150M (2019), and reported at a total of $200M by the Nov 5, 2021 ribbon-cutting. The record showed $300M, which we could not source; $200M is the last figure we could confirm, and the total may have grown further since 2021 without a source we found.

Michigan's governor's office held a ribbon-cutting for the completed Ann Arbor facility on Nov 5, 2021; the record showed Jan 1, 2022.

The Chandler Connection facility officially opened on Thursday, Apr 20, 2023, per the City of Chandler; the record showed Jan 1, 2023.

Lam Research broke ground on a new AI-era R&D lab at its Tualatin campus on Aug 26, 2026, with a Washington County/Tualatin agreement covering up to $1.7B in investment through 2041 and the lab projected to open in 2028. The record showed this as operational since 2023 at $1.0B, which does not match any announcement found.

Washington County's Strategic Investment Program agreement covers up to $1.7 billion through 2041; the record showed $1.0B.

The new Oregon lab is projected to open in 2028, per coverage of the Aug 26, 2026 groundbreaking; the record showed 2023.

Entegris celebrated the grand opening of its Colorado Springs Manufacturing Center of Excellence on Nov 5, 2025; the record showed Jan 1, 2023, which predates even the Dec 2022 announcement of the project.

Gresham's own multi-year expansion is described as an $800 million initiative (separate from the $880M figure for Microchip's Colorado Springs site, which the record had duplicated here).

Governor Abbott's office announced (Apr 18, 2019) that the new RFAB2 facility represents 'more than $3.1 billion in capital investment'; the record showed $3.0B, a close but imprecise figure.

TI's own blog post says RFAB2 started initial production in September 2022, 13 years after RFAB1 opened; the record showed Jan 1, 2022.

This was a retrofit of an existing site, not a new fab: NXP invested about $100 million over three years to convert it to a 150mm RF GaN fab. The record showed $2.0 billion, off by roughly 20x.

NXP opened the GaN fab on Sep 29, 2020; the record showed Jan 1, 2024, which appears to have been confused with an unrelated date.

No field value changed here; this entry records context only. Press reports (Aug 2026) say Nokia will acquire NXP's Chandler GaN fab, leasing part of it from early 2027 and completing the purchase in Q1 2029, with NXP closing its own use of the site by 2027. Our status field still shows Operational, which is accurate today, but this project should be revisited as that timeline approaches.

The record's investment (NT$100B) and 2023 production date match UMC's Fab 12A Phase 6 (P6) expansion, announced Apr 28, 2021. A separate, still-unbuilt Phase 7 (P7) only had its fab shell announced in Jul 2026 with no production date, and does not match this record. Renamed from P7 to P6 to reflect the sourced facts; the two phases were likely confused when the record was created.

Intel's own release states Fab 9 opened on Jan 24, 2024; the record showed Jan 1, 2023.

This is a facility modernization, not a new fab: the U.S. Commerce Dept's Dec 2024 preliminary CHIPS Act terms describe a total project cost of about $127 million (up to $16M in CHIPS direct funding plus other financing), improving wafer capacity by 30%. The record showed $1.3 billion, which appears to be off by roughly 10x.

Press coverage says Bosch's Dresden wafer fab opened in June 2021 (a EUR 1 billion investment, its largest ever at the time), with further incremental investment announced in 2022 and 2023. The record showed Jul 1, 2022. The record's $3.0B investment figure could not be matched to a single Bosch statement this round and is left unverified rather than changed on an uncertain match.

The Elec (Jul 30, 2026) reports Taylor Fab 2 construction is scheduled to begin by the end of 2026, with commercial production currently targeted for 2030. The record previously had no date (TBD) after an earlier, unsupported 2029 figure was removed.

Digitimes (Feb 20, 2025) reports SMIC's Beijing fab expansion (second phase) at a total investment of at least CNY 50 billion (about US$6.86 billion); the record showed $7.6B with no identifiable source.

TSMC's Arizona page states it broke ground on the third fab (N2/A16) in April 2025; the record still showed Announced.

NXP's Dec 4, 2024 release describes VSMC 'celebrating breaking ground' on the 300mm fab, so construction has started; the record showed Announced.

No GlobalFoundries or government statement giving a production date for the new Malta fab was found. The Feb 2024 announcement says construction was scheduled to begin in 2025 but states no production date; the record's Jan 2027 figure had no source.

Reports say PSMC's board confirmed it is ending its partnership with SBI Holdings on the Miyagi JSMC project, with PSMC declining to assume the project's risk; SBI says it intends to continue by finding a new partner. The record showed Under Construction with no indication of this. Not marked Cancelled because SBI has said it intends to proceed.

GlobalFoundries officially opened its $4 billion Singapore expansion fab (Fab 7h) on Sep 12, 2023; the record showed Jun 1, 2023.

Purdue University's release of the Aug 27, 2026 groundbreaking describes the project as a $4 billion investment; the record showed $3.87B.

Amkor's Oct 2025 groundbreaking release headline states the investment was expanded to $7 billion across two phases; the record showed $2.0 billion.

Press coverage of the Oct 2025 groundbreaking says construction of the first facility completes mid-2027 with production beginning early 2028; the record showed 2027. Amkor's own release body was not opened to confirm the exact wording.

Micron broke ground on the Hiroshima expansion on Jul 4, 2026 (investment reported at about JPY 1.5 trillion, with up to JPY 500 billion of METI subsidy). Trade press reports equipment installation is set for the second half of 2028; the record showed 2027, which predates the groundbreaking itself.

The EPIC Center was announced for an Applied Materials campus in Silicon Valley (Santa Clara, CA), not Austin, TX; the record had the wrong city, state and project name. Investment was also updated from $4.0B (the original May 2023 figure) to $5.0B, per Applied's Feb 11, 2026 release.

Applied's Feb 11, 2026 release describes the EPIC Center as its 'multibillion-dollar' campus and cites approximately $5 billion; the record showed the original $4.0B figure from the May 2023 announcement.

The record's Jan 2025 target has already passed with no Intel confirmation of production start. Press (Tom's Hardware) reports Fab 62 is expected to be ready around 2028, but Intel has not stated a date, so the field now shows TBD.

TrendForce (Jul 31, 2026) reports Israel withdrew a $425M grant for Intel and the Kiryat Gat expansion remains uncertain, following an earlier construction halt. Intel has not restated a production date since pausing the project, so the 2028 date is removed.

The record's Jan 2025 target has passed. Trade press describes TSMC's AP7 advanced-packaging complex at this Chiayi site as targeting equipment move-in for Phase 1 in 2026 and mass production in 2027; investment for this entry is unchanged and unverified.

Samsung said in March 2026 that it has no specific timeline to build a second fab in Taylor; the city council is preparing for possible first steps as early as the end of 2026, depending on market conditions. The 2029 date shown before was not supported by any Samsung statement, so it now shows TBD.
