Patent ID: 6879380

Claim:
A lithography system which forms a predetermined development pattern on a substrate applied with a photosensitive material, the lithography system comprising: an applying apparatus which applies the photosensitive material to the substrate; an exposure apparatus which exposes the substrate applied with the photosensitive material; a developing apparatus which develops the exposed photosensitive material; a control system which controls the exposure apparatus so that the substrate, to which the photosensitive material has been applied by the applying apparatus, is exposed with a light beam via a predetermined evaluating pattern by the aid of the exposure apparatus; a sensor which measures a state of a development pattern of the photosensitive material obtained by developing the substrate exposed by the exposure apparatus by using the developing apparatus; and a judging system which judges one of: (i) a characteristic of the applying apparatus, (ii) a characteristic of the exposure apparatus, and (iii) a characteristic of the developing apparatus which affect the development pattern respectively, independently from the other characteristics, on the basis of measurement information obtained by the sensor.
