Abstract:
1. A substrate processing system comprising: a coating unit which coats a resist on a substrate; a developing unit which develops the resist on the substrate; an etching unit which performs an etch process on the substrate after development in the developing unit; an inspection unit which measures a feature associated with the substrate both: (a) after completion of development in the developing unit and before etching of the substrate in the etching unit, and (b) after etching of the substrate in the etching unit; and a controller in communication with the inspection unit and at least one of the coating unit, the developing unit, and the etching unit so that a process in at least one of the coating unit, the developing unit and the etching unit is changed based on (1) a measured feature measured by said inspection unit and (2) a plurality of contribution degrees associated with process changes and associated with respective effects on said measured feature associated with the substrate.
