IQE's 2021 capex cut probably has no impact to Aixtron.
On July 14 2021, IQE reported:
"Orders placed for three new Aixtron G4 reactors and three refurbished Aixtron G3
reactors, with delivery of tools expected in H2 2021 to increase capacity at IQE Taiwan
by over 20%, underpinning further anticipated growth in 2022 and beyond"
On Nov 24, IQE updated:
"Despite the challenges of supply chain constraints within the broader semiconductor industry,
the solid performance of GaAs throughout 2021 has resulted in high utilisation at the Group’s
Taiwan facility, where the Group is investing in eight new and refurbished tools. This includes
three new Aixtron G4 reactors which are now on-site and being commissioned to support
further growth in 2022."
So three G4 have been delivered and installed and the 2021 capex cut just announced should not affect the MOCVD.
