In an effort to learn more about the nature and distribution in size of particles encountered in device fabrication, we have studied the non destructive inspection performance obtained with standard and low voltage scanning electron microscopes. To simulate particle defects in and on layers, diamond particles with known size were used. This present study proves that the low voltage SEM is an excellent tool to detect and measure very small particle defects on layers but the performance for particles within layers is marginal.
