Experimental Studies of Shape Measurement Thin Film by Interferometry Techniques

The paper predominantly accentuates on the experimental studies of shape measurement for thin film by Interferometry Techniques. The research challenge in this study is technical hitches on shape of surface measurement of Indium Tin Oxide (ITO) thin film using conventional technologies. The way out of this research challenge is to measure the shape of the thin film based on sinusoidal phase modulation with interference signal, error value and shape value in nanometer range. The impartial of this research is to accomplish enhanced enactment of the thin film shape measurement in the range of nanometer skill. The experimental results in this study confirm that the measurement technique of thin film in this study was encountered the high performance applications in actuality. The investigations were conceded out with the experimental methodologies by complimentary the numerical approaches in the laboratory.
