Nanoparticle size and shape evaluation using the TSOM optical microscopy method



Ravikiran Attota, Richard J. Kasica, Lei Chen, Premsagar P. Kavuri, Richard M. Silver, Andras Vladar


We present a novel optical TSOM (through-focus scanning optical microscopy - pronounced as 'tee-som') method that produces nanoscale dimensional measurement sensitivity using a conventional optical microscope. The TSOM method uses optical information from multiple focal planes for dimensional analysis. Even though the TSOM method can be used to analyze nanoscale dimensional and defect analysis for a wide variety of target geometries and sizes, we present here an application of the method for size and shape analysis of nanoparticles. We present the analysis based on simulations and also provide experimental data.
