A method of heat-treating resist coated manufacturing wafers in a processing system by establishing a temperature profile for each of a plurality of hotplates in the processing system, heat-treating the resist coated manufacturing wafers on the hotplates, obtaining CD metrology data from test areas on the heat-treated resist coated manufacturing wafers, determining CD variations for each hotplate from the CD metrology data, adjusting the temperature profile of one or more hotplates after determining the CD variations, and heat-treating additional resist coated manufacturing wafers on the hotplates after the adjusting. |
