<<Using a standalone inspection tool to determine endpoint for an etch or CMP step, for instance, would mean removing the tool from the chamber, inspecting it, and putting it back, repeatedly.>>

Do you mean removing the tool from the chamber or removing the wafer?

I can see how there would be specific applications where it could make sense, particularly in process control examples such as you cited; I was referring to defect detection tools in general.

I do think your points about the need for independence and impartiality in dealing with fabs are important ones, by the way.
