Compare Gemini and Landmark with Gemini:
Determining who has the "higher" capacity depends entirely on whether you are looking at sheer volume (the whole company) or photonics specialization (the AI-grade stuff).
In 2026, the two companies are effectively the "David and Goliath" of the epi-wafer world:
1. Total Company Scale (IQE is much larger)
If you look at the total number of MOCVD (Metal-Organic Chemical Vapour Deposition) reactors—the machines that grow the wafers—IQE is significantly larger.
IQE: Operates 100+ reactors globally.
LandMark: Operates roughly 25–30 reactors.
IQE is a massive "supermarket" of wafers. They produce high volumes of Wireless (GaAs) wafers for mobile phones and power electronics in addition to their photonics business. LandMark is a specialized "boutique" focused almost exclusively on photonics.
2. Photonics Specialization (LandMark is more "Pure Play")
When it comes to Indium Phosphide (InP)—the specific material used for AI data center transceivers (800G and 1.6T)—the gap narrows significantly:
LandMark: As of April 2026, LandMark is reportedly operating at full capacity with its 30-ish reactors dedicated primarily to high-end optical communications. They are the go-to partner for many Tier-1 hyperscale suppliers in Asia and the US.
IQE: While IQE has more total machines, only a portion of their fleet is configured for high-end InP photonics. However, IQE’s massive Newport "Mega-foundry" in the UK was built specifically to house dozens of these machines. In 2026, IQE is finally filling that "empty" space with photonics orders.
3. The "6-Inch" Shift
The real capacity battle in 2026 is about wafer size:
IQE's Advantage: They are a leader in moving photonics from 4-inch wafers to 6-inch (150mm) wafers. One 6-inch wafer provides more than double the surface area of a 4-inch wafer. By transitioning their large fleet to 6-inch production, IQE can technically achieve a much higher total output of chips than LandMark using the same number of machines.
LandMark's Response: LandMark has traditionally been more agile and has higher "yields" (fewer wasted chips), but they are also scaling up their 6-inch capacity in 2026 to keep pace with demand from 800G/1.6T transceiver manufacturers.
