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 9):
The method of  claim 8 , wherein generating an arm scan profile further comprises:\n setting an arm scan path that controls movement of the nozzle during etching to cause the nozzle to selectively dispense an etchant onto each of the plurality radial locations; and defining an arm scan speed at each of the plurality of radial locations as a function of the etch depth at respective radial locations, wherein the, arm scan path, arm scan speed and etch time controls the amount of etchant that is dispensed on onto each of the plurality radial locations during etching.
