The paper presents investigations of the surface roughness of epitaxial silicon films obtained by chemical vapour deposition with chloric and MOCVD processes. The flat surfaces of films and chemically etched surfaces of substrates were studied by optical methods as well as by X-ray reflectivity at grazing incidence. The computer simulations based on Fresnel theory were compared with the experimental results.
