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 16):
The method of  claim 1 , wherein the etch recipe includes an arm scan profile, wherein the arm scan profile controls movement of the arm during the first etching step causing a nozzle to selectively dispense a first etchant onto each of the plurality radial locations thereby selectively thinning the wafer at each radial location, and further comprising:\n displaying, by the processor on a display, an interactive graphical representation of the arm scan profile, wherein the arm scan profile is represented as a chart including a plurality of points having a first value on a first axis that corresponds to a respective radial location parameter and second value on a second axis that corresponds to a respective arm scan speed parameter at the respective radial location; receiving at the processor, a user interaction with a particular point on the graphical representation of the arm scan profile, wherein the user interaction includes a manipulation of one or more of the first value and the second value; updating, with the processor according to the manipulation of the one or more of the first value and the second value, one or more of the respective radial location parameter and the arm scan speed parameter in the arm scan profile; and wherein the wafer is etched using the single wafer wet etching apparatus according to the updated arm scan profile.
