Abstract:
A system and method for performing a wet etching process is disclosed. The system includes multiple processing stations accessible by a transfer device, including a measuring station to optically measure the thickness of a wafer before and after each etching steps in the process. The system also includes a controller to analyze the thickness measurements in view of a target wafer profile and generate an etch recipe, dynamically and in real time, for each etching step. In addition, the process controller can cause a single wafer wet etching station to etch the wafer according to the generated etching recipes. In addition, the system can, based on the pre and post-etch thickness measurements and target etch profile, generate and/or refine the etch recipes.

Claim (Index 15):
The method of  claim 5 , further comprising:\n in the event that the measured post-etch thickness of the wafer does not match the final target wafer thickness profile,\n recalculating the first-etch depth based on the measured post-etch thickness and the target thickness of the respective radial location after the first etching step; \n generating an updated first etch recipe; and \n re-etching the wafer according to the updated first etch recipe.
