Abstract: A cooling controller receives, from one or more sensors, wafer information associated with a wafer. The cooling controller determines a pattern mask area for the wafer based on the wafer information. The cooling controller determines a cooling time for the wafer based on the pattern mask area. The cooling controller causes a cooling plate to cool the wafer for a time duration equal to the cooling time. Determining the cooling time for a wafer based on a pattern mask area provides stable and consistent wafer temperatures for wafers having different mask and layout properties, which reduces mask overlay variation and increases wafer yield.

Abstract: A collaborative seam tracking method based on laser line scanning sensing includes: scanning, by using a laser line scanning sensor, a weld seam to obtain an original sampling deviation value; coordinate converting the original sampling deviation value to obtain a converted sampling deviation value, and then obtaining a first converted sampling deviation coordinate based on a current position coordinate of a motion mechanism; in response to an absolute difference between the converted sampling deviation value and a position value of a corresponding projection point on a preset path is less than a processing range of a galvanometer, performing a seam tracking; in response to the absolute difference between the converted sampling deviation value and the position value of the corresponding projection point on the taught path is greater than or equal to the processing range, performing Hermite interpolation, thereby obtaining an interpolation function as a motion trajectory.
