Patent ID: 7337019

Claim:
A method for processing wafers in a manufacturing execution system using a run-to-run controller with a fault detection system, said method comprising: 1) receiving, into said run-to-run controller, a recipe for controlling a tool, wherein said recipe includes at least one setpoint for obtaining one or more target wafer properties; 2) monitoring processing of said wafers by measuring processing attributes including wafer properties and fault conditions identified by said fault detection system; 3) forwarding said processing attributes to said run-to-run controller; 4) modifying said at least one setpoint of said recipe at said run-to-run controller according to said measured processing attributes to maintain said target wafer properties, except when a fault condition is detected by said fault detection system in which case the at least one setpoint of said recipe is not modified according to said measured processing attributes; and 5) incorporating said modified setpoint of said recipe as a parameter in said fault detection system.
