MPCVD is a chemical vapour deposition process which uses a continuous microwave source to create and help to maintain a highly reactive plasma made up of the reacting chemicals and necessary catalysts.

MPCVD is heavily used in the ANFF network to deposit layers of diamond – methane and hydrogen are introduced and used to grow new diamond on a diamond-seeded substrate.

ANFF equipment can introduce dopants to the carbon structure while its being grown. These include boron which can create superconducting diamond, and nitrogen vacancies which can produce interesting photo-luminescence properties that are being exploited for quantum information systems.
