Paper Abstract

Chemically vapor deposited diamond films have a potential for optical applications but so far only translucent films have been produced. The reason for the low transparency is considered to be related to the polycrystalline nature of the films and to defects. To elucidate the problem and indicate ways of improving film quality, the growth mechanism of CVD diamond must be understood. In microwave plasma assisted CVD the plasma is induced by microwaves in a mixture of hydrogen and methane. A high concentration of atomic hydrogen, much above the thermal equilibrium concentration, helps to prevent codeposition of graphite. The growth of diamond occurs in a narrow temperature range (900-1000°C) as a result of the interplay of several phenomena.
