WebThe Semilab AMS IR family of products uses proprietary model-based infrared reflectometry to measure thickness, depth and parameters of etched and recess filled trench structures with nanometer precision. It can also measure epitaxial layer thickness with angstrom precision even at 30 nm and below. WebFT-IR analysis is further used to confirm the introduction of the different functional groups onto the surface of SiO2 spheres. Figure 4a shows the FT-IR spectrum of the bare SiO2 spheres. The absorption peak at 1020 - 1110 cm-1 is assigned to the Si-O-Si asymmetric stretching vibration, and the peaks at 960 cm-1 are ascribed to the asymmetric bending …
