Abstract:
1. A substrate processing system comprising: a coating unit; a developing unit; an etching unit; an inspection 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; wherein the controller controls at least one process of at least one of the coating unit, the developing unit and the etching unit to at least one of: 1) coat a resist on the substrate in the coating unit, 2) develop the resist on the substrate in the developing unit, and 3) etch the substrate in the etching unit after development in the developing unit; and wherein the inspection unit 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 wherein the controller controls at least one of the coating unit, the developing unit and the etching unit such that one or more processes 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.
