Intense has a strategic partnership with the III-V wafer specialist
IQE, the world’s largest outsource supplier of III-V epiwafers. IQE
offers a diverse range of materials produced using the MOCVD
(Metal Organic Chemical Vapour Deposition) and MBE (Molecular
Beam Epitaxy) crystal growth platforms.

IQE’s European manufacturing facility and international HQ are
based in Cardiff UK. The partnership involves IQE growing complex
compound semiconductor crystal structures to Intense’s design.
Wafer growth is a critical element in Intense’s supply chain, and the
alliance allows Intense to achieve economies of scale through
accessing the largest independent manufacturing capacity
worldwide. IQE supplies Intense with both gallium arsenide (GaAs)
and indium phosphide (InP) based epitaxy structures.
