WebThe Lighting reflects on the film surface. The image is not affected by the film. It is necessary to bring out the contrast between the surface of the chip and the print by eliminating the reflection from the transparent film (halation). The optimum method is to use diffuse reflection to prevent specular reflection on the transparent tape. WebReflection absorption spectroscopy (RAS) is extremely effective for measurement of thin films on metallic substrates; however, this method is unsuitable for measurement of thin films on non-metallic substrates such as glass, silicon wafer and plastics.
