Abstract
This paper reviews the ?state-of-the-art? of the vapour phase deposition
of cubic boron nitride (cBN) in terms of the nucleation and growth
processes on ion bombardment, and provides an insight into the solution
of the inherent disadvantages of ion-assisted processing for cBN
deposition. To this end, current experimental and theoretical topics
related to the vapour phase deposition of cBN are examined, and the
initial growth stage is discussed in conjunction with recent findings
derived from novel sputtering and plasma chemical vapour deposition.
Finally, a qualitative growth scheme of cBN is proposed based on
the concept of dynamic compressive strain, and research needs for
the future development of cBN thin films are identified.
