Abstract
A method of depositing thin films of silicon based compounds, particularly silicon dioxide, by cathode reactive sputtering utilizes a rotating cylindrical magnetron driven by a d.c. potential. The result is a technique of forming a uniform film on large substrates with high deposition rates. Arcing normally associated with sputtering troublesome dielectric coatings such as silicon oxides is substantially eliminated.
