Abstract PROBLEM TO BE SOLVED: To provide a method for detecting generation of a foreign substance on a reticle for manufacturing a semiconductor device. SOLUTION: An inspection portion where a light non-transmitting portion and a light transmitting portion are laid is provided on a pattern face of a reticle substrate. An effective transmittance in a predetermined region including at least a part of the light non-transmitting portion and at least a part of the light transmitting portion is measured. A foreign substance on the reticle is detected based on the effective transmittance. COPYRIGHT: (C)2008,JPO&INPIT
