Chip Supply Roundup: A Bigger Dresden, Sold-Out Optics and Two Smaller Moves

Four chip-industry items from 8 and 9 October 2026 touch European wafer capacity, the lasers inside AI data centres, chip packaging and AI chip design. Each is labelled by how certain it is. TSN offers no investment advice.

GlobalFoundries: Dresden expansion tops out, and a new platform is planned

Confirmed (company release). GlobalFoundries (GF) marked the topping-out of its SPRINT expansion in Dresden on 9 October. GF says it is “investing €1.1 billion” and expects the project to raise annual capacity “to more than one million 300mm wafers by the end of 2028”, which would make Dresden “Europe’s largest foundry site” (GF’s own description) [1]. Today the site has capacity of “up to 950,000 300mm wafers, depending on product mix”, employs “around 3,000 people”, and has received “more than €10 billion” of GF investment since 2009 [1]. GF says this construction phase finished “on-schedule and on-budget” (company statement) [1].

Planned, not started. GF also announced FDX Fusion, a chip-making platform “planned for development and manufacturing” in Dresden and aimed at “Physical AI” such as robots and vehicles. GF says it “targets 7nm-like digital performance” [1]. The release’s footnote matters: “The actual start of the FDX Fusion development work is contingent upon the Federal Government’s approval of IPCEI AST project start” [1]. In other words, Germany must approve the funding project before development work begins. GF’s chief executive, Tim Breen, said: “Europe’s industrial base depends on chips that have to be available, trusted and built close to the customers who rely on them” [1].

This is separate from GF’s US interposer deal with TSMC, covered by TSN on 9 October.

Lumentum: “completely sold out” through early 2029

Spotted via Arby The Alpha Bull (@RanjitAlpha) on X.

Reported (Bloomberg interview; the CEO’s statements). Lumentum makes indium phosphide laser devices used in the optical links inside AI data centres. Bloomberg reports that its optical components are “completely sold out” through early 2029, “according to its chief executive officer”, Michael Hurlston [2][3]. In an interview in Tokyo on Friday 9 October, Hurlston said Lumentum “is unable to meet about 70% of demand for some products through next year, and won’t be able to address 30% of demand for some other products through 2028” [2][3]. Bloomberg adds: “Just six months ago, Hurlston said Lumentum was on track to sell out its capacity by 2028” [2].

Bloomberg says Lumentum “received an investment of $2 billion from Nvidia earlier this year along with rival Coherent” [2]. That wording does not make clear whether $2 billion went to each company or was the total, so TSN repeats it as written.

How Lumentum is adding capacity

Reported (Bloomberg interview; the CEO’s statements and Bloomberg’s reporting). Hurlston told Bloomberg: “We are really trying to catch up, add capacity as fast as we can, but we are very, very far behind what customers want … We are completely sold out, so there’s no end in sight” [2]. According to Bloomberg, Lumentum “has ramped up capacity 12-fold at its key factory in the Tokyo metropolitan area over the past two years”. It “plans to invest at least $350 million in the site and a neighboring facility”, and has “also expanded capacity at its plant in Caswell, England” [2]. Bloomberg describes Lumentum’s facility in Sagamihara, Kanagawa Prefecture, as “one of the world’s most advanced indium phosphide device production sites” [2]. The $350 million is a plan, and Bloomberg gives no timetable for it.

Relief is slow, and customers are sharing the bill (reported). Bloomberg reports: “It takes three to five years for companies like Lumentum to build new production capacity. But hyperscalers have agreed to take on some of the capital spending risk, Hurlston said.” In his words: “These hyperscalers are willing to put money behind it” [2]. Hyperscalers are the biggest cloud and AI data-centre operators. Bloomberg adds that “big tech providers have been offering guarantees for long-term agreements” to reassure key suppliers [2]. Neither Hurlston nor Bloomberg names the customers or the terms.

Confirmed (company release), from earlier this year. In March, Lumentum announced a US plant in Greensboro, North Carolina, bought from Qorvo, to make indium phosphide laser devices. Lumentum says the site “is expected to ramp production in mid-2028” and that it “plans to invest hundreds of millions of dollars over the next several years” there [8].

CEO intention. Bloomberg reports that to widen its product range Lumentum will need to consider an acquisition. Hurlston: “I think probably in the next year, we’d like to add additional capability to what we currently have” [2]. No target or deal has been announced.

Unconfirmed: a possible US ban. Bloomberg says the sector is bracing for further supply constraints “as the U.S. reportedly considers a ban on new Chinese optical transceiver models” [2]. Bloomberg cites no official source for this, and TSN has not confirmed that any such ban is under consideration. Bloomberg also cites Counterpoint Research’s view that Lumentum and Coherent “would not be able to fill the vacuum left by Chinese makers such as Innolight” [2]. That is the research firm’s assessment.

Unisem: a RM396 million packaging proposal in Malaysia

Proposal (company filing, as reported). Unisem (M) Bhd told Bursa Malaysia on 9 October that it “proposes to undertake a Phase 2 expansion” of its Gopeng plant in Perak [4]. According to The Star, the plan is a 40,000 sq m production facility “for an estimated cost of RM196mil”. Half of it would be leased to its subsidiary Unisem Advanced Technologies (UAT) to expand wafer bumping, which adds the tiny solder contacts that join chips to packages. UAT’s fit-out is “estimated to cost RM200mil”, bringing the total to “about RM396mil” [5]. Unisem says the aim is “to capture growing demand for advanced packaging, particularly in Artificial Intelligence (AI), data centres, and high-performance computing applications” [5]. No timeline was given.

Phinity: a $5.2 million seed for AI chip design

Funding confirmed; performance claims unverified. Phinity Labs came out of stealth on 8 October saying it has raised “$5.2 million in seed funding led by Uncork Capital, with participation from Moxxie and angels including Jeff Dean”, after a pre-seed led by Pear through PearX [6]. It builds AI that designs chip hardware. Phinity says it has “reached 8-figures in annualized run rate”, works with “some of the largest foundation model labs” (not named), and that its system “produces verified designs an order of magnitude faster with better power, performance, and area than experienced hardware engineers” [6]. These are company claims. Phinity has published no benchmark or customer names to support them.

What this does not prove

• That FDX Fusion is under way. GF says development depends on German government approval of the IPCEI project start [1].
• That Dresden will reach one million wafers a year. That is GF’s expectation for the end of 2028 [1].
• That Lumentum’s shortage is industry-wide. The sold-out figures are its CEO’s statements to Bloomberg about his own company [2][3].
• That new capacity will ease the shortage soon. The 12-fold increase and the $350 million plan are reported by Bloomberg, and Bloomberg says new capacity takes “three to five years” to build [2]. Lumentum’s Greensboro plant is expected to ramp only in mid-2028, by the company’s own estimate [8].
• That the US will ban new Chinese optical transceivers. That possibility is only “reportedly” being considered, according to Bloomberg, and is unconfirmed [2].
• That Unisem will build the plant. It is a proposal, with no timeline [4][5].
• That Phinity’s designs beat human engineers. That claim and its revenue figure are unverified [6].

The Bottom Line

GF has topped out a €1.1 billion Dresden expansion and plans a new physical-AI platform that still needs Berlin’s approval. Lumentum’s CEO says its AI optics are sold out into early 2029, even after a reported 12-fold capacity increase at its main Tokyo-area plant; new capacity takes years to build, and he says hyperscalers have agreed to share some of the investment risk. Unisem proposes RM396 million for more packaging capacity, and Phinity has raised $5.2 million on claims it has yet to show publicly. Together they point to optics and packaging, not just processors, as pinch points in AI hardware.
