Abstract :
While thin film diamond can be grown by a number of techniques which vary widely in their deposition rate, the technique using microwave plasma assisted chemical deposition (MPACVD) leads in the production of high-quality, high-purity films. Thus, despite its relatively low deposition rate, it remains attractive for many applications in electronics and optics which require high quality material. AEA Technology have a programme to develop, and make available commercially, diamond deposition equipment using MPACVD processes. The programme consists of two parts: develop an improved reactor for 4in (100 mm) diameter substrates, with 6 kW of microwave power at a frequency of 2.45 GHz; and develop a concept for deposition on 8in (200 mm) wafers at the same frequency. Progress with this work is described
