THERMAL CONTROL SYSTEMS, MODELS, AND MANUFACTURING PROCESSES IN LITHOGRAPHY
Abstract:
Dynamic aberration control in a semiconductor manufacturing process is described. In some embodiments, wavefront data representing a wavefront provided by an optical projection system of a semiconductor processing apparatus may be received. Wavefront drift may be determined based on a comparison of the wavefront data and target wavefront data. Based on the wavefront drift, one or more process parameters may be determined. The one or more process parameters include parameters associated with a thermal device, where the thermal device is configured to provide thermal energy to the optical projection system during operation.
