Abstract

An edge detection scheme for phase change systems is presented. A single split detector is used to detect the intensity of reflected beam in the far field, and the readout signal, which relies on diffraction from mark boundaries, is the difference signal of the split-detector. The magnitude of the readout signal for edge detection is derived by clarifying the effect of phase on the read signal, and comparing noise levels at the output of readout systems using edge detection and sum detection.
