Abstract
Low pressure CVD diamond films are intended for application in the optics, biomedical, electronics and engineering industries. In a number of applications, it is important to know the growth stresses in the films at room temperature and, in addition, the stresses generated in the films as a function of temperature. The results in this paper will show the in situ measurement of stresses in CVD diamond films as a function of temperature up to 750 °C. The principal measurement techniques are Raman spectroscopic analysis and the X-ray diffraction (XRD) sin2ψ method.
