  • Abstract
    A method to estimate a magnitude of resist blur by overlay measurement with a special mark. Because of utilization of optical measurement, line-end-shortening (LES) can be measured with good repeatability, resulting in accurate estimation of a magnitude of resist blur. This method is very useful to estimate resist blur in an advanced lithography era.
