Technical Examples

A management system and method of a reticle in an exposing process are disclosed. A calculator calculates an accumulated dosage of an illuminating light irradiated onto a reticle used in a photolithography process. The calculator is connected to an exposing apparatus to expose photoresist on a semiconductor substrate. A comparator compares the calculated accumulated dosage with a preset reference dosage. When the calculated accumulated dosage is greater than or equal to the reference dosage, a controller suspends the photolithography process. Minimizing haze contamination on the reticle, thus preventing process failures.
