Continuous thin diamond film and method for making same.

摘要

A continuous thin diamond film having a thickness of less than about 2 microns has a low leakage. The thin diamond film may be supported on a supporting grid and may be incorporated into an X-ray window. The film may be formed in a DC assisted CVD process where in a first phase a relatively high concentration of a carbonaceous gas is introduced into the reactor and in a second phase the concentration of the carbonaceous gas is reduced to a lower value.
