Preparation of cubic boron nitride films by reactive sputtering from a boron nitride target

open access: yes, 2022
S.1130-1135PVD sputter deposition of cubic boron nitride (cBN) on Si(001) has been carried out using electrically conducting B4C as target material. While the target was powered with a r.f. generator the substrate electrode was connected to a d.c.

Improvement of the adhesion of sputtered cubic boron nitride films

open access: yes, 2022
Cubic boron nitride (cBN) films were prepared by reactive r.f.-sputtering in an Ar-N2 discharge using an electrically conducting boron carbide (B4C) target. The substrate table was either powered by a r.f.-generator or connected to a d.c.
